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
or unsoldering.
Notes on Chip Component Replacement
· Never reuse a disconnected chip component.
· Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

SERVICING NOTE
1-1. SERVICE MODE
Mode to allow the mechanical parts to operate with the audio board
open.
This set uses the photo reflector PH701 to detect the rotation of the
idler gear (A) (S side). PH701 is on the main board and so removal
of the main board does not allow the set to detect the rotation of the
idler gear (A) (S side). This makes motor control impossible which
prevents normal operation.
When repairing the set as energized with the main board removed,
proceed as follows:
1. Setting
1) Remove the case (refer to the Disassembly) and open the main
board.
2) Connect the motor and plunger to the main board with jumper
wire.
The extension jig (1-769-143-11) (one set of ten wires) can be
used for easy connection.
3) Short the TAPE IN switch land (BP701) with solder. Input a
square (or sine) wave of 10 to 100 Hz (at 1.3 V) to both PH IN T
land (TP60) and PH IN S land (TP61) with jumper wire.
4) Supply 1.3 V to the positive and negative terminals of the
battery with a stabilized power supply.
2. Preset state
The set must be in this state before the PLAY, FF and REW modes
can be entered.
1) Make sure that the slider (NR) is in the center position and that
the N/R switch (S701) is in the center position. Make sure that
the reel gear does not rotate by rotating the flywheel on the F
side clockwise. If improper, place the set in the preset state
according to the following instructions:
2) Repeat the step below some times to ensure the above
conditions.
* Pull away the trigger level from the plunger with twezers or other
means. Then rotate the flywheel on the F side clockwise.
3) Turn the stabilized power supply OFF once and then ON.
3. FF/REW mode
1) Check for "2. Preset state" and push the FF switch and the REW
switch.
2) Move the N/R switch (S701) to the movement of the slider to
enter the FF/REW mode.
4. PLAY mode
1) Check for "2. Preset state."
2) Push the
" " switch on the remote commander to move the
lever (SW) toward the R side. With timing to this, move the
N/R switch (S701) to enter the PLAY (R side) mode.
Note 1: If failed, retry from the preset state.
Note 2: The
" ", p, FF and REW switches on the remote
commander should be used whenever possible.
