FOCUS BIAS CHECK
1. Connect the oscilloscope between IC701 pin wj (or TP (RF))
and GND on CD board.
2. Insert the disc (YEDS-18). (Part No. : 3-702-101-01)
3. Press the CD N X button.
4. Confirm that the oscilloscope waveform is as shown in the
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.
