CD section adjustments are done automatically in this set.
In case of operation check, confirm that focus bias.
In case of operation check, confirm that focus bias.
FOCUS BIAS CHECK
1. Connect the oscilloscope between IC701 pin 4 and pin qa (or
TP (RF) and TP (VREF)).
2. Insert the disc (YEDS-18). (Part No. : 3-702-101-01)
3. Press the N X (CD) button.
4. Confirm that the oscilloscope waveform is as shown in the
3. Press the N X (CD) 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.
