CD SECTION
Note:
1. CD Block is basically designed to operate without adjustment.
Therefore, check each item in order given.
2. Use YEDS-18 (3-702-101-01) unless otherwise indicated.
3. Use an oscilloscope with more than 10MW 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 an oscilloscope to TP (FE) and TP (DVD) on the BD
board.
2. Turn the power ON.
3. Load a disc (YEDS-18) and actuate the focus search. (In conse-
quence of open and close the disc tray, actuate the focus search)
4. Confirm that the oscilloscope waveform (S-curve) is symmetri-
cal between A and B. And confirm peak to peak level within 2 ±
0.5 Vp-p.
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.
RF  LEVEL  CHECK
Procedure :
1. Connect an oscilloscope CH1 to TP (RFDC), CH2 to TP (RFAC)
and TP (DVD) on the BD board.
2. Turn the power ON.
3. Load a disc (YEDS-18) and playback the number nine track.
4. Confirm that oscilloscope waveform is clear and check if RF
signal level is correct or not.
Note:
Clear RF signal waveform means that the shape “ 
◊ ” can be
clearly distinguished at the center of the waveform.
TRAVERSE LEVEL CHECK
Procedure :
1. Connect an oscilloscope to TP (TE) and TP (DVD) on the BD
board.
2. Turn the power ON.
3. Load a disc (YEDS-18) and playback the number nine track.
4. Press the  G  (RV20) or  gG  (RV50/RV60) button. (Becomes
the 1 track jump mode.)
5. Confirm that the level B and A (DC voltage) on the oscilloscope
waveform.
