Generated separately:
Hard-copy of User Manual (printed by GMA; stored in projector case)
Authorized but not purchased:
USB storage device (it may be more practical for users to supply their own if they wish to use the
“viewer” function)
Other items under consideration (not in original or amended proposals):
1. Compact surge protector (to be purchased, replacing G. Aronson’s, on loan)
2. Spare remote control (purchased: stored in drawer with sound system keys)
3. Adapter and 82 mm clear or “UV” filter to protect the lens, plus a snap-in lens protector with
tether. This would replace the tethered lens cap supplied with the projector.
Built-in security features of projector:
None are implemented as of this writing. See full user manual for details.
We have decided not to implement any of the security functions at this time.
II. Basic Operating and Safety Guidelines
These are highlights only. Please read the user manual carefully for more complete information.
1. Keep projector away from direct sunlight, heaters, heat-radiating appliances, smoke, or steam.
2. Don’t tilt the front of the projector up or down by more than 7 degrees from level while
projector is on. Not following this may shorten the bulb life.
3. Don’t look into the lens (or permit anyone else to) while projector is on, as serious eye damage
could result.
4. Don’t cover the lens with the supplied (or any other) lens cap while the projector is on. Not
following this could melt the cap and cause burns to the hands. (To temporarily darken the
projected surface, use the “Pic Mute” (i.e., “Picture Mute”) button on the remote control. This
blackens the screen and also mutes any sound coming out of the projector. Press this button again
to resume picture display.)
5. Lamp (bulb) replacement (only by authorized A/V person!):
a. To replace the lamp (bulb), follow all instructions on page E-8 of user manual.

Rev. March 4, 2006
b. Be sure to replace the lamp when the message “THE LAMP HAS REACHED THE
END OF ITS USABLE LIFE. PLEASE REPLACE THE LAMP” appears. If you
continue to use it, the lamp bulb may shatter and pieces of glass may be scattered in the
lamp case.
c. Allow a minimum of 90 seconds to elapse after turning off the projector. Then turn off
the main power switch, disconnect the power cable, and allow 60 minutes (one hour) to
cool down the projector before replacing the lamp.
d. To monitor the lamp usage periodically, use the remote control’s “menu” button and
navigate to the “Information” tab and select “Usage Time.” (The bulb is rated at 2000
hours in regular mode and 4000 hours in “eco” mode (less brightness).)
e. For comparative purposes, as of 12-6-05, both the bulb and projector usage display
as 32 hours.
6. If the projector is to be used with a laptop/portable computer, be sure to connect the VGA cable
to the laptop BEFORE powering on the computer, to avoid damage to it, and to ensure that the
computer will recognize the projector.
7. Exercise great caution when attempting to clean the projector’s lens. If unsure how to do it
safely, consult with someone who does. Often, use of an air blower (without a brush) is all that’s
needed. Cleaning with lens tissue or a treated cleaning cloth designed for photographic lenses
should be left to a specialist.
8. Before putting the projector in the soft case, be sure to retract the feet. Failure to do so may
cause the damage to the projector.
9. Do not unplug the power cable from the wall outlet under any one of the following
circumstances. Doing so can cause damage to the projector:
a. While the projector's lamp lights.
b. While the cooling fans are running. (The cooling fans continue to work for
90 seconds after the projector is turned off).
c. While the PC CARD Access Indicator lights. Doing so can damage your
PC memory card.

III. Most typical connections to external
devices

Also refer to diagrams on following pages.
A. DVD or VHS video tape player:
DVD player:
First choice for the video signal would be an “S-Video” connector from player to projector.
Choose the “S-Video” source using the projector’s remote control. This will give a far better
picture. Second choice would be a (usually yellow) “composite” RCA-type cable from player to
projector. Choose the “Video” source using the projector’s remote control. Sound connections, see
computer connections. Note: start the volume control very, very low!
(Potential upgrade: a roughly $25. adapter would permit the maximum quality “component” video
signals (3 outputs) from a DVD player to connect to the VGA input of the projector.)
VHS player:
(There’s no “S-Video” connection unless it’s an “S-VHS” player, which are relatively rare).
Connect the yellow “composite” RCA-type cable from player to projector as in DVD. Choose the
“Video” source using the projector’s remote control. Sound connections, see computer
connections.
B. Windows or Mac portable computer:
a. Turn off the power to your projector and computer.
b. Use the supplied RGB/VGA signal cable to connect your PC or Macintosh to the projector.
Note: some MACs require an adapter to fit the VGA cable and/or VGA inputs on the projector.
c. Connect the supplied power cable.
d. Turn on the projector and the computer.
e. If the projector goes blank after a period of inactivity, it may be caused by a screen saver
installed on the computer you've connected to the projector. (I.e., turn off screen or power savers
on the computer, and temporarily disable anti-virus automatic update settings or scheduled
scanning settings, as these could cause unplanned and unwanted disruptions to the presentation.)
Connect the other end of the VGA signal cable to either the “Computer 1” or “Computer 2”
connection on the back of the projector. The former is a better bet since it supports “plug-andplay” protocols.
With the remote, select “Computer 1” as the input source. This handles the visual signal only. If
audio is being generated from the computer at the same time, you need to connect the “audio out”
(or “headphone” or similar) jack on the computer either to the “audio in” jack on the projector or
to the “house” sound system.
The built-in sound system on the projector is low-powered and low-fidelity. Use only in small
gatherings or as a backup to using a more robust sound system.

Connecting to our Meeting Room’s sound system:
A convenient way to do this is to use the line-to-microphone level “EDB Direct Box” stored near
the microphones. One takes sound output from the computer (or similarly from a DVD or VHS
player) and connects it to the ¼” phone jack on one side of this block. One of our standard
microphone cables is then plugged into the other side of this block, and the other end into either
the left or center microphone XLR jacks on the Meeting Room steps. The volume can then be
controlled from a combination of the device’s and the mixing board’s volume controls.
If a hum is heard through the loudspeakers, flip the “ground lift” switch on the EDB Direct Box to
its opposite position.
Adapters of various kinds may be needed to accommodate the various audio output possibilities on
a laptop or media player.
C. Using an external storage device (either USB or “Compact Flash”)
Image files of certain formats may be stored on an external device and displayed through the
projector via the “Viewer” function.
The images can be set to change at set time intervals or be changed manually via the remote
control.
With software supplied with the projector, one can take a Microsoft PowerPoint presentation and
convert it into a series of images to be displayed without use of a computer. (Note that fancy
transitions and animations employed have little or no support.)
The great advantage of using this feature is that no laptop is needed during a presentation, nor are
the uncertainties regarding connectivity going to be an issue.
But there is a caution that this needs to be tried out before the presentation! Not all external storage
devices are supported (and it’s not clear which are or aren’t) and not all variations on supported
file formats are supported!
