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.
