Notice that the minus side of a tantalum capacitor may be dam- aged by heat. 3 SECTION 1 SERVICING NOTES SERVICE MODE This set detects the rotation of the idler gear (A) (side S) using the photo refl

8、ector (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 b

9、oard removed, the mechanism posi- tion cannot be detected and the operation is not changed over. Therefor, when the voltage check is executed 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 boar

10、d 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), TAPE DETECT switch (S702-2), REC PRO- TECT (FWD) switch (S

11、703-1) 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 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

12、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 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-

13、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 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

14、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 switch (S701) according to t

15、his timing will set the REC or PLAY mode (side F). Press the REC switch (S6) or PLAY/DIR botton (S3) another time and move the DIRECTION switch (S701) according to the movement of the slider (NR) will set the REC or PLAY mode (side R). Note 1: If the above fails, perform from preset again. Note 2: U

16、se each button on the remote controller as much as possible. If no remote controller, do not touch the buttons with your hands, but using a stick with a round tip. Note 3: When using headphones, the timing for move the DIRECTION switch (S701) can be determined from the beep sound. REC PROTECT DETECT
