1. Connect the oscilloscope between IC701 pin 4 and pin qa (or
TP (RF) and TP (VC)).
2. Insert the disc (YEDS-18). (Part No. : 3-702-101-01)
3. Press the NX (CD) button.
4. Confirm that the oscilloscope waveform is as shown in the
3. Press the NX (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.
