RF RV101 IC101 RV103 TEO FEO VC RV102 TEI FEI FOK
Procedure: 1. Connect a lead wire to the test point TP501 on Display board. 2. Connect oscilloscpe to test point TP (TEO) on BD board. 3. Turned power switch on, load the disc (YEDS-18). 4. 5. 6. 7. Connect a lead wire connected to the test point TP501 to ground. Press the TIME button. (TRACKING SERVO OFF) Playback the disc (YEDS-18). Confirm that the oscilloscope waveform is symmetrical on the top and bottom in relation to 0Vdc, and check this level.

level: 300 ± 100 mVp-p
Specified level: �
A�B x 100 = less than ± 7% 2 (A + B)
[DISPLAY BOARD] � Conductor Side �
� A + B = 300 ± 100 mVp-p 8. Remove the lead wire connected in step 1. Focus/Tracking Gain Adjustment (RV102, RV103) This gain has a margin, so even if it is slightly off. There is no problem. Therfore, do not perform this adjustment. Please note that it should be fixed to mechanical center position when you moved and do not know original position.
