Note:
1. CD Block is basically designed to operate without adjustment.
Therefore, check each item in order given.
2. Use LUV-P01 (Part No. 4-999-032-01) unless otherwise indi-
cated.
3. Use an oscilloscope with more than 10MW impedance.

cal between A and B. And confirm peak to peak level within 2 ±
0.5 Vp-p.
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 TP71 (RFDC), CH2 to TP72
1. Connect an oscilloscope CH1 to TP71 (RFDC), CH2 to TP72
(RFAC) and TP73 (DVD) on the BD board.
2. Turn the power ON.
3. Load a disc (LUV-P01) and playback the number nine track.

3. Load a disc (LUV-P01) 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.
