In case of operation check, confirm that focus bias.
FOCUS BIAS CHECKTest Point:
1. Connect the oscilloscope between IC701 pin 4 and pin qa (or
� CD board (conductor side) �
TP (RF) and TP (VREF).
2. Insert the disc (YEDS-18). (Part No. : 3-702-101-01)TYTX
3. Press the CD N X button.
4. Confirm that the oscilloscope waveform is as shown in the
figure below. (eye pattern)
A good eye pattern means that the diamond shape ( ) in the
center of the waveform can be clearly distinguished.TP(TE)
