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 dam­aged by heat.

SERVICING NOTES

SERVICE MODE
This set detects the rotation of the idler gear (A) (side S) using the photo reflector (PH701). The PH701 is mounted on the MAIN board, therefore the idler gear (A) (side S) cannot be detected with the MAIN board removed. As a result, the motor (M601) cannot be controlled, causing malfunction. Further, the DIRECTION switch (S701) is also mounted on the MAIN board, and with the board removed, the mechanism posi­tion cannot be detected and the operation is not changed over. Therefor, when the voltage check is e xecuted with the MAIN board removed, follow the procedure provided below.
1. Setting
1) Refer to “3. DISASSEMBLY”, and remove the MAIN board.
2) Connect the MAIN board to the motor (M601) and the plunger (PM701) using jumper wires. These can be connected easily with the use of the extension tool (Part No. 1-769-143-11) (ten in one set).
3) Short each terminals of REC PROTECT DETECT (REV) switch (S702-1), T APE DETECT switch (S702-2), REC PR O­TECT (FWD) switch (S703-1) and ATS switch (S703-2).
4) Connect the AF oscillator to the TP33 (PHOTO IN) and the TP40 (GND).
5) Supply 1.3 V to the battery terminals using the regulated po wer supply.
2. Preset state
T o set the REC, PLAY, FF, REW modes, the preset state must be set.
1) Check that the slider (NR) and the DIRECTION switch (S701) are set to the center position. If not, set the preset state as fol­low.
2) Move the DIRECTION switch (S701) to the side, which the slider (NR) is facing.
3) The slider (NR) will move when the regulated power supply switch is set to OFF once and then set to ON. Move the DI­RECTION switch (S701) according to this timing and set to the center position.
3. FF, REW modes
1) Check that the preset state is set.
2) Input the square wave or sine wave to the TP33 (PHOTO IN) and the TP40 (GND).
3) Press the [FF/CUE ] button (S4) or the [REW/REVIEW ] button (S5).

4. REC, PLAY modes
1) Check that the preset state is set.
2) Input the square wave or sine wave to the TP33 (PHOTO IN) and the TP40 (GND).
3) Press the [REC] switch (S6) or [PLAY/DIR ] botton (S3)

will move the slider (NR) once towards the side R and then to the side F . Move the DIRECTION s witch (S701) according to this timing will set the REC or PLAY mode (side F). Press the
