The PH701 is mounted on the MAIN board, therefore the idler gear (A) (side S) cannot be detected with the MAIN board remo

9、ved. 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 posi- tion cannot be detected and the operation is not changed over. Therefor, when the voltage check is exe

10、cuted 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

11、 No. 1-769-143-11) (ten in one set). 3) Short each terminals of REC PROTECT DETECT (REV) switch (S702-1), TAPE DETECT switch (S702-2), REC PRO- TECT (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 t

12、erminals using the regulated power supply. 2. Preset state To 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 fol- low. 2) Move the DIRECTION switch (S701) to

13、 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 DI- RECTION switch (S701) according to this timing and set to the center position. M Y m Y 3. FF, REW modes 1) Check that the preset state i

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 t

15、he REC switch (S6) or PLAY/DIR botton (S3) will move the slider (NR) once towards the side R and then to the side F.
