 CD SECTION
Note:
1. CD Block is basically designed to operate without adjustment.
There-fore, check each item in order given.
2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.
Use a disc copied from YEDS-18 for CD-RW test.
3. Use an oscilloscope with more than 10M
Ω 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.
OP FE Offset Adjustment
Procedure:
1.
Connect a digital multimeter to test point TP704 (FE,Y F X)
and TP703 (VREF) with DC range.
2.
Turn on the power, while pressing two buttons  u  and
 PLAY MODE  simultaneously. “
88” is displayed.
3.
Press the  x  button,then press the  PLAY  MODE  button.
Adjust the RV701 after the message “
82” is displayed.
4.
Press the  PLAY MODE  twice. Adjust the RV702 after the
message “
82” is displayed and “REP” blinks.

OP TE Offset Adjustment
Procedure:
1.
Connect a digital multimeter to test point TP705 (TE,Y T X)
and TP703 (REF) with DC range.
2.
Put the disc (YEDS-18)  in.
3.
Press the  u  button.
4.
Adjust the RV703 after TOC reading.
TE Specified value: VREF – (100 
± 20mV)
RF Waveform Check
Procedure:
1.
Connect an oscilloscope to test point TP702 (RF) and TP703
(VREF) on the CD board.
2.
Put the Disc (YEDS-18 or copied from YEDS-18) in.
3.
Press the  u  button.
4.
Confirm that oscilloscope waveform is clear.
Note:
A clear RF signal waveform means that the shape “
◊” can be clearly
distinguished at the center of the waveform.
