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

figure below. (eye pattern)
A good eye pattern means that the diamond shape ( ) in the
center of the waveform can be clearly distinguished.
