NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. Laser component in this product is capable of emitting radiation exceeding the limit for Class 1.

When V (CURSOR DOWN) button is pressed, GEQ decreases to its minimum and a message "GEQ MIN" appears. 6. When b (CURSOR LEFT) or B (CURSOR RIGHT) button is pressed, GEQ is set to flat and a message "GEQ FLAT" appears. 7. In the test mode, the default-preset channel is called even when the TUNER is selected and an attempt is made to call the preset channel that has been stored in memory, by operating the Shuttle knob. (It means that the memory is cleared.) 8. When a tape is inserted in the Deck B and the TAPE B function is selected, and when the REC PAUSE/START button is pressed twice, recording starts. The VIDEO function is selected automatically as the input source. 9. Select the desired loop by pressing the PLAY MODE button in the TAPE B function. Insert a test tape AMS-110A or AMSRO to Deck A. 10. Press the SPECTRUM button to enter the AMS test mode. 11. After a tape is rewound first, the FF AMS is checked, and the mechanism is shut off after detecting the AMS signal twice. 12. Then the REW AMS is checked and the mechanism is shut off after detecting the AMS signal twice. 13. When the check is complete, a message of either OK or NG appears. 14. When the two buttons of SPECTRUM and DISC1 are pressed at the same time in any function modes, either the "VACS ON" display to enable the VACS function or the "VACS OFF" display to disable the VACS function can be selected. 15. When you want to exit this mode, press the ?/1 button twice. The cold reset is enforced at the same time.

[VIDEO CD Color-bars Mode] On this mode, the data of the color-bars signal as a picture signal and the 1 kHz sine wave signal as a sound signal are output by the mechanism controller (IC502) for the video CD signal check. When measurement of the voltage and waveform on the VIDEO board, perform it in this mode. For reference, the color-bars signal can be observed at CN301 (VIDEO OUT) using an oscilloscope. Procedure: 1. Short the both ends of the land of SL503 of the VIDEO board. 2. Turn the power on. Press the CD button to select CD. 3. The color-bars appears when the CD is in stop status, and it disappears when the CD goes in play status. 4. After measuring, remove the lead wire connected.VIDEO board (SIDE B) [CD Servo ON/OFF Mode] Procedure: 1. Short SL502 on the VIDEO board by soldering. 2. Turn on the main power. Set a disc on the DISC1 tray. Select CD. 3. Press the hH button to play back CD. 4. When the > + button is pressed, 100 track jump is executed. 5. Also, every pressing of the PLAY MODE button triggers between ON and OFF of TRACKING SERVO and SLED SERVO. How to quit the CD servo ON/OFF mode: 1. Press the ?/1 button to turn off the main power. 2. Remove soldering from SL502.

2) Operation during aging mode In the aging mode, the program is executed in the following sequence. (1) Rewind is executed up to the top of tape A and B. (2) A tape on FWD side is played for 2 minutes. (3) FF is executed up to either made for 20 second or the end of tape. (4) A tape is reversed, and the tape on REV side is played for 2 minutes. The tape on the REV side is played in both A and B. (5) Rewind is executed up to the top of tape. (6) Returns to step 2, and repeat steps from 2 to 5. [Function Change Mode] * Select either VIDEO or MD of the external FUNCTION input. Procedure: 1. Turn on the power. 2. Press the two buttons MD (VIDEO) and ?/1 at the same time. The main power is turned on and the other function of the previous function is selected and displayed. "MD" or "VIDEO".

1. CD Block is basically designed to operate without adjustment. Therefore, check each item in order given. 2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated. 3. Use an oscilloscope with more than 10M impedance. 4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks. S-Curve Check

Procedure : 1. Connect oscilloscope to TP (FE0). 2. Connect between TP (FEI) and TP (VC) by lead wire. 3. Connect between TP (AGCCON) and TP (D GND) by lead wire. 4. Turn Power switch on. 5. Load a disc (YEDS-18) and actuate the focus search. (In consequence of open and close the disc tray, actuate the focus search) 6. Confirm that the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 4 ±1 Vp-p.
S-curve waveform symmetry
Procedure: 1. Supply a 98 MHz signal at 60 dB from the ANTENNA terminal. 2. Tune the set to 98 MHz. 3. Measure voltage between pin 21 and pin 23 of IC 101. Adjust T101 ubtil the voltage becomes 0 V. Adjustment Location: MAIN board

7. After check, remove the lead wire connected in step 2 and 3.
Note : · Try to measure several times to make sure than the ratio of A : B or B : A is more than 10 : 7. · Take sweep time as long as possible and light up the brightness to obtain best waveform.
