4-3. CLV-S MODE
The spindle servo for playback sets into the CLV-S mode when the TP21 (ADJ) terminal is connected to Ground after turning on the power.

4-4. AGING MODE

This unit is equipped with an aging mode to check operations of the mechanism deck. When faults occur: Aging stops, and the state when aging stopped is displayed on the fluorescent display tube. When no fault has occurred: Aging is continued repeatedly. Aging method 1 (When using the aging mode remote controller (J-2501-123-A)): 1. Press the U button and turn ON the power. 2. Set the disc on the tray. 3. Press the AGING START button of the aging remote controller. 4. Aging starts and the message shown in Fig. 1 is displayed on the fluoresent display tube. 5. To end, press the U button. Aging method 2 (When no aging mode remote controller): 1. Press the U button and turn ON the power. 2. Set the disc on the tray. 3. Press the OPEN/CLOSE button, p button, and MUSIC SCAN button at the same time. (If these buttons are not pressed at the same time, nothing performs.) 4. Aging starts and the message shown in Fig. 1 is displayed on the fluoresent display tube. 5. To end, press the U button.

SECTION 5 ELECTRICAL BLOCK CHECKING
Note: 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

E-F Balance (1 Track Jump) Check (Without remote commander)

oscilloscope SERVO board

Procedure : 1. Connect oscilloscope to test point TP (FE) on SERVO board. 2. Connect between test point TP (FEI) and TP (VC) by lead wire. 3. Turn U (power) switch on. 4. Put disc (YEDS-18) in and turn U (power) switch on again and actuate the focus search. (actuate the focus search when disc table is moving in and out.) 5. Check the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 31 Vp-p.

S-curve waveform symmetry
Procedure : 1. Connect oscilloscope to test point TP (TE) on SERVO board. 2. Turn U (power) switch on. 3. Put disc (YEDS-18) in to play the number five track. 4. Press the P (Pause) button. (Becomes the 1 track jump mode) 5. Check the level B of the oscilloscope's waveform and the A (DC voltage) of the center of the Traverse waveform. Confirm the following : A/B x 100 = less than 22%

1track jump waveform

A within 3 1Vp-p B
Center of the waveform B A (DC voltage) 0V level : 1.3 0.6 Vp-p
6. After check, remove the lead wire connected in step 2. 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.
