Control
16
Description
LCD
The liquid crystal display (LCD) of the Model 390 mimics the LCD of the
MTM700/800 Motorcycle Control Head, and shows the current radio status.
Typical information displayed includes current call information, aliases, and a
data or status message. The LCD also shows a set of status icons on the top
row (see LCD Icons on page 21).
Volume
The volume level of the front panel speaker and the handset earpiece are
adjusted at the same time by turning the Volume knob.
Scroll Keys
These keys allow a user to scroll through messages in the stack, a list of preprogrammed groups, options, or radio IDs. These are the same as those
programmed into the radio (for more information, see the radio’s user guide).
Cancel Key
This key is used to cancel a call, erase an entry, or delete a message. This key
functions in the same way as the key on the control head.
Select Key
To select options when the  appears in the display, press this key. It can also
be used to select other options, such as the desired talkgroup or range.
Phone Call Key
This key places the radio into phone mode, which allows connection to the
phone system on equipped systems. With the handset off hook and the PTT
bar pressed in, a full duplex call is possible.
Direct Mode (DMO) Key
This key allows local radio-to-radio communications without using the
repeater. This function is typically used if a site is down or unreachable for
some reason. When in direct mode, the LED next to the key will be on. The
same radio functions allowed in direct mode are available through the remote.
To enter the direct mode, hold this key down for a period of time until the
mode initiates (the length of time may vary from radio to radio depending on
its programming).

Radio Functions
Control
Description
Emergency Key
This key allows the remote to send an emergency call (see the radio’s user
guide for more information). The Model 390 Interface may be configured to
trigger an external remote output on receipt of an emergency call.
Private Call Key
This key allows the radio to be placed into private mode. Use the
alphanumeric keypad to select a recipient or use the Scroll keys to select from
a list. (The Model 390 Interface may be configured to trigger an external
remote output on receipt of a private call.)
Transmit (PTT) Key
To key the radio, first select the recipient or group, using the appropriate
keys, then press the Transmit key on the remote. There will be a delay while
the radio negotiates and acquires a channel. This delay is dependent on the
radio and traffic on the system.
If the recipient is unavailable or the system is busy, a tone is heard and the
LCD displays any message from the radio. Once the channel has been
acquired, the TX LED turns on to indicate that the unit is transmitting.
Now begin speaking into the Model 390 Remote. Its internal microphone is
located near the front, right edge of the unit, and picks up a person’s voice at
an arm’s distance, though audio quality improves as the distance is decreased.
Release the Transmit key to hear receive audio from the front panel speaker.
To use the handset to key the radio, remove it from the cradle. Press the PTT
bar and wait for the TX LED to come on steady. Speak into the handset
mouthpiece. Release the PTT bar to hear receive audio from the handset
earpiece.
To clear down a call, press the Cancel, Group, or another mode key.
External Alarm Key
This key allows a user to change the status of the external alarm output on the
radio. This is usually used to trigger some external event when a call comes
in. This key functions in the same way as the External Alarm key on the
control head. This function is different from the private and emergency call
triggers that can be set on the remote.
Menu Key
To change or verify menu features of the radio, hold down the Mute key and
press and release the Private Call key. The current radio settings will be
displayed. Press the combination again to select the next setup menu. Use the
Select key to change a setting.
Alphanumeric Keypad
These keys function as a 12-key keypad for alphanumeric entry, dialling, or
selecting a talkgroup. This keypad works just like the control head keypad.
Hook Switch
The hook switch on the remote has the same function as that of the hook/clear
button on the rear of the radio’s mic. This allows a user to cancel or clear
down a call by placing the handset on hook.
Progress Tones
All progress tones generated by the radio will be heard either from the front
panel speaker or from the handset earpiece, depending upon whether or not
the handset is off hook. For more information about progress tones, refer to
the radio’s user guide.

Operation
Additional Model 390 Remote Functions
Function
Intercom Key
Description
Intercom mode allows users at various Model 390 Remotes to talk to one
another without keying the radio and tying up a channel.
To enter intercom mode:
1. Press the Intercom key. The Intercom LEDs on all the Model 390
Remotes will flash.
2. To talk to someone at another Model 390 Remote, press and hold the
Transmit key while speaking into the front panel microphone, or remove
the handset from the cradle and press and hold the PTT bar while
speaking into the handset. While any Model 390 Remote is sending
audio, the Intercom LEDs on all the Model 390 Remotes turn on steady.
3. To listen for a response, release the Transmit key or the PTT bar.
4. To exit intercom mode, press the Intercom key on any Model 390
Remote. The Intercom LEDs will all turn off.
As long as the Intercom LED is flashing, the system is in intercom mode, and
pressing the Transmit key or the PTT bar does not key the radio, but only
transmits to the other Model 390 Remotes on the system. While listening in
the intercom mode, receive audio from the radio can still be heard.
If no key is pressed on any Model 390 Remote for 30 seconds, intercom mode
times out, and the system returns to normal operation.
Intercom mode may be disabled through system programming. For
information on disabling intercom mode for a single Model 390 Remote, see
Remote Configuration on page 29.
Mute Key
18
To mute the receive audio of any Model 390 Remote, press the Mute key.
The Mute LED will turn on and a positive indication beep will be heard from
the remote to indicate that the receive audio is muted. Note that mute mode
does not time out and that it does not affect any other Model 390 Remotes. To
unmute the audio, press the Mute key again, and the Mute LED turns off.
025-9448D
Additional Model 390 Remote Functions
Function
Secure Mode Key
Description
Secure mode allows a user at one Model 390 Remote to talk to someone over
the air without anyone at parallel Model 390 Remotes hearing either side of
the conversion or being able to control the radio. It effectively locks these
users out, leaving one person in full control of the radio.
NOTE: Even in secure mode, communications over the channel occur
normally, giving no additional security beyond that which the radio provides.
To enter secure mode, press the Secure Mode key. The Secure Mode LED
comes on. The Secure Mode LEDs on all the other Model 390 Remotes blink
to indicate that they cannot control the radio. The Mute LEDs also illuminate
on all the Model 390 Remotes except the one that initiated secure mode to
indicate that their receive audio is being muted.
The radio may be controlled as usual by the person who initiated secure
mode, and current radio status continues to be displayed on all Model 390
Remotes.
As long as the Secure Mode LED is on, users at all other Model 390 remotes
will be unable to receive audio or key the radio.
To exit secure mode, the initiator must press the Secure Mode key again. If
no keys are pressed on the initiating Model 390 Remote within 60 seconds,
however, secure mode times out, and the system returns to normal operation.
Additionally, returning to normal operation when the secure mode initiator
hangs up the handset can be set in system programming.
Secure mode may be disabled for all remotes in system programming. See
System Parameters on page 42.
For information on disabling the secure mode for an individual Model 390
Remote, see Remote Configuration on page 29.
Supervisor
Any number of Model 390 Remotes in a system may be configured as
Supervisors. These remotes are immune from the effects of secure mode. In
other words, when another Model 390 Remote initiates secure mode, all
Supervisor remotes are still able to hear both sides of the conversation and
control the radio.
Furthermore, when a Supervisor remote initiates secure mode, the mode does
not time out.
For more information on configuring Model 390 Remotes, see Remote
Configuration on page 29.

Operation
Function
Supervisor Takeover
Description
There are two types of supervisor takeover: 1) A Supervisor remote may be
configured so that it can “kill” an undesirable call without waiting for keys to
be released, and 2) Any remote (Supervisor or not) may be configured so that
it can physically disconnect downstream remotes from the system for a more
positive form of control.
Pressing the Secure Mode key initiates supervisor takeover.
The first type of supervisor takeover occurs when a Supervisor remote enters
secure mode. The second type of supervisor takeover requires that
“supervisor takeover” be selected in system programming. The FET output of
the remote is then used to control an external relay, which is used to
disconnect the downstream remotes. The output is a pull-to-ground and
remains active for as long as secure mode remains in effect.
For more information on using this output, see Section 4, “Installation.”
The FET output can alternatively function as an incoming call trigger. (see
the following entry: Incoming Call Trigger)
Incoming Call Trigger
If the disconnect-type supervisor takeover function is not used, a setting in
system programming allows the FET output on remotes to be used to trigger
an alarm or other notification of an incoming private and/or emergency call.
For more information on using this output, see Remote Configuration on page
29.
Adjacent Deskset Muting
When two or more Model 390 Remotes are located in the same room or
within earshot of one another, audio feedback may be a problem. When one
user keys the radio, the audio will be heard at the other Model 390 Remote
and may cause feedback to the first. To prevent this, each Model 390 Remote
may be individually configured to mute its receive audio while another Model
390 Remote is transmitting.
For more information on enabling this option, see Remote Configuration on
page 29.
Radio Reset
Sometimes it is desirable to reset the radio remotely, usually as a last resort.
By pressing the Mute and Cancel keys on a radio-reset-enabled remote, the
radio interface will attempt to cycle power on the radio. All users will receive
a notification before this takes place.
It should be emphasized that this feature is designed to be a last resort method
of gaining control of the radio. The user should probably attempt to force the
radio to re-register by changing modes first. If the user has to perform this
task often, it may be a symptom of some other problem with the radio or
radio settings.
For more information on configuring the Model 390 Remote, see Remote
Configuration on page 29.

Description
Desk Microphone
An external dynamic desk microphone may be connected to a Model 390
Remote to key the radio while the handset is on hook. If connected properly,
it will operate just like the front panel microphone.
External Amplified
Speaker
An external amplified speaker may be connected to a Model 390 Remote in
addition to, or in place of, its front panel speaker. The Volume knob
simultaneously adjusts both the volume of the external speaker and the
volume of the front panel speaker if connected.
Headset
An optional headset interface box may be used to plug a headset into a Model
390 Remote in place of the handset. Alternatively, a headset with flying leads
may be connected directly to screw terminals in the Model 390 Remote. In
either configuration, the headset replaces the handset. There are three possible
setups for switching between the headset and the front panel speaker and mic
(or desk mic):
1. Permanently enable the headset, thereby permanently disabling the front
panel microphone and speaker as well as any desk microphone and
external amplified speaker. This involves shorting two screw terminals
together. The radio is taken on and off hook by lifting the handset from
and replacing it to its cradle.
2. Leave the handset in its cradle while using the front panel microphone and
speaker, then lift the handset off hook while using the headset. Use an
external closure to ground, such as a footswitch, to activate the headset.
Press the switch to use the headset. Release the switch to use the front
panel microphone and speaker. Again, the radio’s hook switch is
controlled by the handset’s hook switch, regardless of the state of the
headset.
3. Use the jack sense signal on the optional headset interface box to activate
and deactivate the headset. Plug the headset into the box to use it, and
unplug the headset to use the front panel microphone and speaker. Just as
with the first possible setup, the radio hook switch is controlled by the
handset’s hook switch, regardless of the state of the headset.
Footswitch
A footswitch may be used to control PTT for the front panel microphone or
an external desk microphone. Footswitches may also be used for headset PTT
and headset takeover. Headset takeover controls whether the headset or the
front panel mic and speaker are active.
Recorder
An external recording device may be used to record all TX and RX audio
from and to a Model 390 Remote. TX audio and RX audio are summed
together and presented to the Recorder Audio output. The recorder will be
activated whenever RX audio is present and also whenever that Model 390
Remote is transmitting (over the air or in intercom mode).

Overview
Installation
!
Caution!
This equipment generates, uses, and can radiate radio
frequency energy. If not installed and used in accordance
with the instruction manual and commonly used radio
practices, it may cause interference to radio
communications. Installation of the Model 390 Radio
Remote system should be accomplished by personnel who
have experience with remotes and radio systems.
Overview
Figure 4 shows a typical system installation, with the Model 390 Radio Interface colocated with the radio. As shown in the figure, a modular telephone cable connects the
interface to a telephone wall jack. In-building telephone wiring connects that wall jack to
a punchdown block in a central location. In-building telephone wiring also runs from this
punchdown block to wall jacks near the desired locations of the Model 390 Remotes.
Finally, modular telephone cables connect the Model 390 Remotes to these wall jacks,
completing the circuit. The remotes can either sit on a desk or be mounted on a wall.
!
Caution!
The radio and the radio interface should be co-located
whenever possible. The interface should NOT be separately
grounded. It is important that the radio interface ground is
through the radio interface cable and the radio.
25
Installation
Figure 4: Typical System Installation
Required Equipment
The only equipment required is some assorted hand tools. However, to install in-building
telephone wiring to the punchdown block and jacks, additional tools may be needed.
Installation Phases
Installing the Model 390 Radio Remote system can be broken down into three phases:
1. Configuring system components
2. Installing and connecting system components
3. Initializing the system
Before starting to install the system, be sure to read through this entire section to become
familiar with the components, the system functions, and how different settings interact
with each other. Before starting, you should know which system functions you want to
enable for which remotes. For example, which remotes in the system are to be Supervisor
remotes?
Phase 1 — Configuring System Components
The first phase involves configuring the radio, the interface, and then the remote.

Phase 1 — Configuring System Components
Radio Requirements
!
Caution!
Do not plug the fist-microphone into the MTM800E radio control heads as
this is known to cause audio distortion issues. The use of a fist
microphone causes the audio levels to drop dramatically requiring a M390
reset.
Model 390 for MTM700/800 (901-9617)
The radio must be equipped with the Expansion Head, which provides a DB25 connector
on the front panel for connection to the Model 390. Do not attempt to use an
MTM700/800 radio with the Standard Control Head with the Model 390. The keys and
indicators of the Model 390 Radio Remote emulate the MTM700/800 Motorcycle
Control Head. If using an MTM700/800 equipped with the Motorcycle Control Head,
disconnect the Motorcycle Control Head and attach the Model 390 in its place.
Radio Configuration
To ensure correct operation of the radio and remotes, it is recommended that the radio be
set up for use as though it had a full feature front panel attached, using the RSS (Radio
Service Software) and adapter (or equivalents) from Motorola.
!
Caution!
The radio should be programmed without the radio interface
connected.
Interface Configuration
Configuring the interface consists of setting jumpers on the interface’s PCB (printed
circuit board) if necessary. Most of the jumpers can be left in their default settings
(position A). The jumpers and their functions are described in Table 1. Figure 5 shows
the approximate location of the jumpers.

Phase 2 — Connecting System Components
Once all the components of the system have been configured, they must be installed and
connected properly. There are four aspects to this step: in-building wiring, radio
connections, interface connections, and remote connections. Do not apply power until all
the system components have been configured and connected (see Power-up on page 36).
In-building Wiring
The connection between the remotes and the radio interface requires three twisted pairs
of wires, 24 gauge or larger. Typically this would be in-building telephone wiring
terminating at modular wall jacks at the locations of the radio interface and each remote.
The modular cables supplied with the radio interface and remotes require 6-conductor
RJ11 jacks where pins 1 and 6 make a pair, 2 and 5 make a pair, and 3 and 4 make a pair.
The remotes may be connected in any configuration (star, T, or multi-drop) as long as no
remote is located more than 600 meters (electrically) from the radio interface.
31
Installation
Radio Connections
Install the radio per the Motorola installation manual. To minimize noise pickup and
crosstalk, avoid placing the antenna and its cable close to the power cables of the radio or
close to the modular cables from the interface to the remotes.
Note
If a control head is attached to the radio, remove it to ensure
correct operation.
Do not apply power until all the system components have been configured and connected
(see Power-up on page 36).
Interface Connections
The radio interface should be co-located with the radio whenever possible. It is connected
to the radio with the 8-pin RJ-45 radio interface cable, Part No. 709-7585 for the
MTM700/800. It is connected to the remotes with a 12-foot, modular cable (Part No.
709-7416).
Interface to MTM700/800 Connections
To connect the interface to the MTM700/800, complete the following steps using Zetron
Radio Interface Cable 709-7585:
♦ Connecting to the MTM700/800:
1. Connect the DB25 connector of the interface cable to the DB25 connector on the
front panel of the MTM700. Secure the connector by tightening the jack screws.
2. Connect the modular end (RJ45) of the radio interface cable to the 8-pin telco
socket on the rear of the interface (marked “To Radio”).
Note
When connecting to an MTM700/800 radio, use Zetron cable
709-7585. Do not use a cable with the pinout shown in Figure 44.
Interface-to-Remote Connections
Connect the 6-conductor telco modular cable to the 6-pin telco socket (RJ11) on the rear
of the interface and to the wall jack.
32
025-9448D
Phase 2 — Connecting System Components
System Programming
Now is an ideal time to program the radio interface if desired. Refer to Section 5,
“Programming”, for more details.
!
Caution!
It is important to disconnect the programming cable from
the interface front panel once the correct system
parameters have been programmed into the interface.
Remote Connections
Figure 7 shows the connectors on the remote’s main PCB for power, the in-building
telephone wiring, and audio accessories and the FET output, which is used for supervisor
takeover or incoming call triggering.
Power
Power must be supplied to the Model 390 Remote through TB1 on its main PCB. If a 12
VAC wall transformer is used, connect it to pins 1 and 2 of TB1. If a 12 VDC supply is
used, connect the positive side to pin 1 and the ground side to pin 3 of TB1. Do not apply
power until all the system components have been configured and connected (see Powerup on page 36).
Figure 7: Connectors on the Remote Main PCB
Remote-to-Interface Connections
Use the supplied 6-conductor modular cable to connect J6 on the remote’s main PCB to
the in-building wiring that runs to the radio interface.

numbers: 415-0705 (clip), 220-0007 (screw).
025-9448D
Phase 2 — Connecting System Components
♦ Mounting a remote to a wall:
1. Remove the back cover, rotate it 180° and reattach it.
2. Carefully remove the clear plastic insert under the handset used to cover the
phone number blank.
3. Insert the handset clip (415-0705) into the socket that the plastic insert was
covering. Be sure that the “tooth” to support the handset is facing out and that the
screw hole matches up with the one in the faceplate.
4. Use the screw (220-0007) provided with the clip to secure the clip. Cover the
screw by replacing the plastic insert in its original position.
5. Use the holes on the back cover to mount the remote to the wall.
Table 5: Connections for TB3 on the Remote Main PCB
Function
Desk Microphone
Connections
Connect the audio signal from the desk microphone to TB3 pin 2 (Desk Mic
Audio). If there are two audio lines, connect one to TB3 pin 2 and the other
one to TB3 pin 3 (Ground).
Connect the PTT signal to TB3 pin 1 (External PTT). This must be a closure
to ground when active (keyed). If the mic’s PTT output consists of two wires,
connect one to TB3 pin 1 and the other to TB3 pin 3. Make sure that JP8 is in
the position A to activate the desk mic when this input goes active.
Connect the microphone’s ground lead to TB3 pin 3.
Headset
If the headset interface box is used, plug the headset into the interface box.
Unplug the handset from the remote and plug the interface box into the jack
where the handset was attached (J5 on the remote’s main PCB).
If the jack sense signal from the headset interface box is used to control
headset takeover, connect it to TB3 pin 6 (Headset Takeover).
If the headset has flying leads, connect the headset mic audio to TB3 pin 4
(Headset mic) and the headset speaker audio to TB3 pin 7 (Headset speaker).
Connect the ground lead to TB3 pin 3 (Ground). If the headset has a PTT
switch, connect it to TB3 pin 5 (Headset PTT).
If a footswitch or other closure to ground is used for the headset PTT, connect
one end of it to TB3 pin 5 and the other end to TB3 pin 3.
If a footswitch or other closure to ground is used for headset takeover,
connect one end of it to TB3 pin 6 and the other end to TB3 pin 3.
Footswitch
If a footswitch or other closure to ground is used as a PTT control for the
front panel microphone, connect one end to TB3 pin1 (External PTT) and the
other end to TB3 pin 3 (Ground). Make sure that JP8 is in position B to
activate the front panel speaker when this input goes active. External Amplified
Speaker
Connect the speaker’s audio input to TB3 pin 9 (External Speaker) and its
ground lead to TB3 pin 8 (Ground). 35
Installation
Function
Connections
Recorder
Connect the recorder’s audio input to TB3 pin 10 (Recorder Audio) and its
ground lead to TB3 pin 8.
Use the output from TB3 pin 11 (Recorder Enable) to enable the recording
device. It pulls to ground whenever there is a signal present to record.
Supervisor
Takeover/Incoming Call
Trigger
Use TB3 pin12 (Supervisor Takeover) to activate an external relay to
disconnect downstream remotes. When this remote initiates secure mode, this
output is pulled to ground.
This output can also be set to be triggered on the receipt of an incoming
private and/or emergency call. This is useful to trigger an external alarm or
notification. When used in this manner, the output can no longer be used for
Supervisor Takeover.
Phase 3 — Initializing the System
The last step is to properly initialize the system. This includes powering up the system
and checking the levels.
Power-up
To power up the remotes, either plug the wall transformer into a power outlet or connect
the 12 VDC supply, as appropriate. To turn the radio interface on, simply plug it into the
radio and provide power to the radio. The interface will turn the radio on and reboot it.
The system should now be functioning.
Level Setting
Interface levels are factory set and should not require adjustment. However, should the
need arise to adjust the audio levels to match local conditions, it is possible to cause the
remote to generate a 1 KHz test tone.
To generate a 1-kHz (approx.) test tone for testing the audio path, simultaneously press
the TX ( TX ) and Intercom ( ) keys on the remote. Press any key to cancel the tone. It
is also possible, if desired, to key up the radio and transmit the tone.
Note
36
While the audio test tone is being generated, it will be heard at
all of the parallel remotes in the system.
025-9448D
Phase 3 — Initializing the System
Programming
The Model 390 Radio Remote system is preconfigured at the factory for the most
common settings. However, some users may benefit from tailoring the system
programming in the radio interface to fit their specific application. The programmable
settings include several radio remote system parameters, as well as the functions of
specific Model 390 Remote keys.
Programming the interface can be done at any time, but it is best performed at initial
system setup.
Note
When the interface is in program mode, the remotes cannot
control the radio.
There are two methods of programming:
•
•
Off-line programming, which involves setting options using a Zetron software
program running on a PC and then downloading the information into the radio
interface. This method reduces system down time while programming and is
much like programming the radio with the RSS (Radio Service Software).
On-line programming which involves setting options using a terminal emulation
program such as Zterm or Hyper-terminal. Special programming software is not
needed.
The following subsections describe the two methods of programming the interface.
37
Programming
Off-Line Programming
Requirements
The optional Model 390 programming kit (Part No. 950-0115), which includes a
programming adapter, programming cable, and the Programming Software.
An IBM PC, XT, AT or compatible computer with DOS version 3.0 or later, 250KB of
free memory, a 3½-inch disk drive, a hard drive with 100KB of free space and a 25-pin
RS-232 serial port (or a 9-pin RS-232 serial port with 25-pin adapter).
Setup
For off-line programming, the Programming Software must be installed on the PC, the
radio interface must be connected to the radio and placed in programming mode, and the
programming adapter and cable must be connected between the PC’s serial port and the
radio interface. The following steps detail this procedure.
♦ Setting up programming software:
1. Install the Programming Software - First, the Programming Software must be
installed onto the PC’s hard drive. Insert the Programming Software diskette into
the PC’s disk drive and, at the DOS command prompt or in the Run dialog box in
Windows, type “a:\setup” if the disk is in drive a:, or type “b:\setup” if the disk is
in drive b:.
The Programming Software prompts you for the drive and directory to install the
software to. Press the Enter key to accept the default, or type in a new drive and
directory. The program is then installed into the specified directory.
2. Configure the Programming Software - Change to the directory into which the
software was installed. If you are using Windows, double click or open the
M390.exe file. If you are in DOS, run the software by typing M390 at the DOS
command prompt.
a. Select the serial port the PC will use to program the radio interface (COM1
or COM2) by selecting Setup | COM port.
b. Select the printer port the PC will use to print the configuration file (LPT1,
LPT2, or a file on disk) by selecting Setup | Printer.
The Programming Software is now configured for use on your system.
38
025-9448D
Off-Line Programming
3. Connect the Programming Adapter - Plug the 25-pin D connector on the
programming adapter into the serial port on the PC. If necessary use a 9-to-25pin adapter. Plug one end of the programming cable into the programming
adapter and the other end into programming port on the front panel of the
interface. Only one end of the programming cable will fit into the port, since its
locking tab is offset to one side.
4. Prepare the Radio Interface - To program the radio interface, it must be
plugged into the radio. Refer to Interface Connections on page 32, for detailed
instructions on installing the radio interface.
When the radio has powered up, press and release the Setup button on the
interface front panel once. The yellow Setup LED should turn on.
Getting Started
The general steps in off-line programming a radio interface are:
1. Open an existing configuration file or read the configuration settings from
another radio interface.
2. Edit the settings as desired for this radio interface.
3. Write the configuration settings to the radio interface.
You may save a configuration file to disk for later use and/or print it out for reference.
Old configuration files may also be deleted from disk from within the Programming
Software.
To reduce system down time, edit the configuration file off-line and put the interface into
programming mode only when you are ready to write the configuration file to the
interface.

025-9448D
Off-Line Programming
Parameter
Description
TX Time-out
Sets the transmit time-out time. The number entered is the number of seconds
that a Model 390 Remote can continually key the radio before the radio
interface will cancel transmit. This may be set from 1 to 127 seconds in
increments of 1 second. The feature may also be disabled entirely by entering
zero (for safety and reliability reasons, this is not recommended). The default
is 127 seconds.
Radio Volume
It is possible to change the default volume level of the radio’s external
speaker. In most scenarios this is not needed, and the setting should be left at
255. Range: 0 – 255.
Selective Audio
When Disabled, this allows the remotes to hear all audio coming from the
radio. This should usually be Enabled to prevent unwanted audio from
reaching the remotes.
Cleardown
When Disabled, this option prevents the hook switch on the remotes from
clearing down a call. This should usually be Disabled so the users in multiremote systems do not inadvertently clear down a call by placing the handset
back in the cradle. When enabled, users can clear down a call by placing the
handset back in the cradle.
Intercom Override
When Enabled, all remotes will hear an intercom message even if muted. This
should usually be Disabled.
Continuity Check
This option allows the remotes to indicate if the data link between remotes
and the interface is functioning correctly. When Enabled, an icon is seen on
the remote display if the interface fails to communicate for 6 minutes.
Reset Enable
This option allows certain remotes to have access to the radio reset feature.
When Disabled, all remotes are able to reset the radio.
Each remote has a FET output which may be triggered by several events.
Parameter
Description
Supervisor o/p
When Enabled, the FET output is triggered when a remote enters secure
mode. This is typically used as a supervisor hard-wire disconnect
Private call o/p
When Enabled, the FET output on the remotes is triggered on receipt of a
private call. This is typically used as an alarm notification in case an operator
is away from the remote (supervisor o/p must be disabled to access this
option). Disabled is the default.
Emergency call o/p
When Enabled, the FET output on the remotes is triggered on receipt of an
emergency call. This is typically used as an alarm notification in case an
operator is away from the remote (supervisor o/p must be disabled to access
this option). Disabled is the default.
Note
When you have finished programming the radio interface, be sure to
cycle power on the radio and to disconnect the programming cable.
When you cycle power to the radio, the interface is taken out of
programming mode and the new settings take effect.

Programming
On-Line Programming
The on-line programming method allows options to be quickly changed in the radio
interface. This method is not designed to be as versatile as the Programming Software,
and it does not allow configurations to be saved to disk or uploaded. However, with online programming you can use programming adapters from some other Zetron products
(contact Zetron for compatibility information).
Requirements
•
A terminal emulation program, such as Zterm or HyperTerminal, running on a
PC with a free serial port
•
•
An RS-232 - TTL cable
A programming adapter with the correct pinout. The programming port on the
front of the interface has its pin positions numbered as shown in Figure 10. The
pin functions are listed in Table 6.

Troubleshooting and Repair
Troubleshooting and Repair
The Model 390 Radio Remote system takes advantage of the latest in hardware and
software techniques to minimize the complexity and parts count of the units. This
provides for better reliability so that the units should not require service. However, in
case of failure, first go through the installation procedure again. If your installation
checks out, your dealer should be able to advise you on troubleshooting the system.
In case of further difficulty, contact Zetron technical support. Please have the serial
number of the unit and/or the Zetron order number. If the call is made from the
installation site by the installer or radio technician, the problem can usually be solved
over the phone.
Service Hints
Problem
Possible Solution
No audio is heard on the remotes or audio is too low
on the remotes.
Make sure that the audio levels have been correctly set
on the radio and that the audio settings are correct in
the RSS (Radio Service Software). Check the version
of the radio code plug. It should be upgraded to
version 2.3 or later. Refer to Section 4, “Installation”,
for more details.
Audio is heard, but the display is blank when the
interface is plugged in.
1. The radio may not recognize the interface. Try
cycling the power to the radio to reinitialize it.
2. The interface is probably not programmed to be
the correct control head for the radio. Reprogram
the interface to change the identity of the interface
to be the other control head type (see
Programming starting on page 37).
3. If a control head is attached to the radio, remove it
for correct operation.
51
Troubleshooting and Repair
Problem
Possible Solution
Audio is heard from the remote, but the display is
blank and the Remote LED on the interface keeps
blinking.
The polarity of the data lines is probably backwards.
Swap JP7 on the interface PCB from position A to
position B, or vice versa.
Audio is heard on the remotes, but a Supervisor
remote is muted when another remote enters secure
mode.
Check jumper JP3 on the Supervisor remote’s main
PCB. It should be in position B.
The In-Use icon is not visible on the display, but the
remote cannot enter secure mode.
If another remote can enter secure mode, check the
JP5 jumper on the keypad PCB of the faulty remote.
The jumper should not be cut (see Remote
Configuration on page 29). If no other remote can
enter secure mode, enable secure mode in system
programming.
Audio is heard on the remotes, but the external
notification for an incoming emergency call is not
working.
1. Check that the notification device has power and
that its connection to the remote’s FET output
(TB3 pin 12 on the remote’s main PCB) is secure.
2. Check the FET output setting in system
programming. Emergency call should be enabled.
3. Check the radio and interface connection (see
Radio Connections on page 32).
A fuse blows.
A blown fuse may indicate that something is not
connected correctly. Check the power connections and
the polarity of connectors.
The following fuses are used in the units:
52
Remote:
1 A, AGC, fast blow
(Zetron Part No. 416-1576)
Interface:

Troubleshooting and Repair
Software Upgrades
From time to time, Zetron may create new versions of the Model 390 operating software.
The changes in new versions range from significant revisions that add new or enhanced
features to minor revisions that correct documented defects. When new software is
available, EPROMs containing the new software for the unit(s) need to be installed.
Procedure
To upgrade to new software and retain your existing programming, complete the
following steps.
♦ Upgrading to new software:
1. If you have made changes to the original interface configuration, document your
existing settings using ZIPR or the Model 390 Programming Software.
2. Install the new EPROMs. See Installing New EPROMs on page 53.
3. If you changed your settings, ensure that they are correct using ZIPR or the
Model 390 Programming Software.
4. Test the unit to verify correct operation.
Installing New EPROMs
New EPROMs that you receive may be for the remote, the interface, or both. Make sure
to put the correct EPROM in the correct unit. The EPROMs have a label with a part
number. Use the part number on the label and Table 6-1 to determine the unit and
location for the new EPROM.

EPROMs are delicate and sensitive to static. When handling
them, be sure to remain grounded by using a ground strap
or, at least, by maintaining contact with a grounded item
such as the radio chassis. Only remove the EPROMs from
the static protective shipping material when ready for
installation.
The following steps outline the EPROM installation procedure.
♦ Installing replacement EPROMS:
1. TURN OFF THE POWER: Unplug the transformer from the remote, and unplug
the cable between the radio and interface.
2. Remove the cover of the unit.
3. Carefully note the location and orientation notch on the end of the old EPROMs.
4. Remove the old EPROMs from the board.
5. Install the new EPROMs in the designated sockets with the orientation notches
aligned with the notches in the sockets.
6. Carefully examine all pins of each EPROM. Make sure pins are aligned in the
sockets, fully inserted and not bent out or under. Ensure that the correct software
is installed in the correct socket.
7. Turn on power to the unit and make sure that the remote gives a normal display
and that the power LED on the interface is lit. If all LEDs are on, there is a
problem. Check again that the EPROMs are properly seated in the correct
sockets.
8. Replace the cover of the unit.
9. Return the old EPROMs to Zetron in the protective shipping material used to
ship the EPROMs to you.
