SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes.).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’ instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indication
is 0.75 V, so analog meters must have an accurate low-voltage
scale. The Simpson 250 and Sanwa SH-63Trd are examples
of a passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2 V AC range are suitable. (See

SECTION 1
SERVICING NOTES
The SERVICING NOTES contains important information for servicing. Be sure to read this section before repairing the unit.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 °C higher
than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.
REPAIRING THE BOARDS
When each board installed in this unit is defective, replace the
mounted board.
Individual electrical parts that mounted on the each board cannot
be replaced.
Printed wiring board and schematic diagram that have been described on this service manual are for reference.
NOTE OF REPLACING THE MAIN BOARD OR THE NFC
BOARD
When replacing the MAIN board or the NFC board, be sure to
replace the MAIN board and the NFC board simultaneously.
The MAIN board or the NFC board cannot replace with single.
Among the repair parts, the MAIN board and the NFC board are
supplied as one unit.

TEST MODE
SOFTWARE VERSION
It can check the information of current software version.
Procedure:
1. Press the [1] button to turn the power on.
2. Press two buttons of the [FUNCTION] and [LIGHT] simultaneously for 5 seconds.
3. Each software version are shown by the blinking frequency of
LEDs simultaneously.
Example:
When the MCU version is “Ver.16”, the [1] LED blinks 1 time,
the [EXTRA BASS] LED blinks 6 times.
When the BT version is “Ver.1.12”, the [ADD L] LED blinks 1
time, the [ADD R] LED blinks 1 time, the [PARTY CHAIN] LED
blinks 2 times.
FACTORY RESET
It can reset all settings and clear the Bluetooth linked list. Execute
this mode when returning the this unit to the customer.
Procedure:
1. Press the [1] button to turn the power on.
2. Press two buttons of the [FUNCTION] and [−] simultaneously
for 5 seconds.
3. Three LEDs of the [1], [ ] and [AUDIO IN] blink for 3 seconds, and then become the standby mode.
