1. Check the area of your repair for unsoldered or poorly-sol
deredconnections. Check the entire board surface for solder
splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
3. Look for unauthorized replacement parts, particularlyt ransis
tors, that were installed during a previous repair.
Point them out to the customer and recommend their
replacement.
4. Look for parts which, through functioning, show obvious
signs of deterioration. Point them out to the customer and
recommend their replacement.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.
5. Check the B+ voltage to see it is at the values specified.
6. Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270°C
during repairing.
• Do not touch the soldering iron on the same conductor of
the circuit board (within 3 times).
• Be careful not to apply force on the conductor when
soldering

ELECTRICAL ADJUSTMENTS
Transmission Frequency Check
1. Set the noise filter SW to OFF.
2. Input a signal of 1 kHz 40 mVrms to only the L-CH (J402).
3. Connect a telescopic antenna to the frequency counter input
and extend the antenna to a length of approximately 8 cm.
4. Place TX-BASE board close to the frequency counter, then mea-
sure the frequencies of CH1, CH2 and CH3 and make sure the
values are as follows:
CH1 : 913.5 MHz ±200 kHz
CH2 : 914.0 MHz ±200 kHz
CH3 : 914.5 MHz ±200 kHz
When the frequency is not satisfied the specified value, set the
channel switch (S402) to CH2, then adjust the value of the
frequency counter to 914.0 MHz by trimmer capacitor in the VCO
unit.
Standard value :913.9MHz to 914.1MHz
When completed with replacement, recheck the
frequencies of CH1, CH2 and CH3.

Pilot signal Modulation Check and Adjustment
1. Set the channel to CH2.
2. An electric wave is output for 5or 10 minutes when OFF to ON a
power supply (Power indicator will ON).
3. Measure the center terminal of RV403 using an digital volt-meter
(AC range) and make sure the value is 2 to 2.5mVrms.
If the measured value is other than the specified value, adjust to
2 to 2.5mVrms by turning the RV403 on the TX-BASE board.

NOTE:
• Due to standardization, replacements in the
parts list may be different from the parts
specified in the diagrams or the components
used on the set.
• -XX, -X mean standardized parts, so they
may have some difference from the original
one.
• Items marked “*” are not stocked since they
are seldom required for routine service.
Some delay should be anticipated when
ordering these items.
• SEMICONDUCTORS
In each case, u: µ, for example:
uA...: µA... , uPA... , µPA... ,
uPB... , µPB... , uPC... , µPC... ,
uPD..., µPD...
When indicating parts by reference number,
please include the board name.
