MAIN BOARD

Procedure:

1. Make a solder bridge to short SL801 (OPEN) on the MAIN

board side A.

2. Connect the oscilloscope to the test point TP604 (RF) and

TP406 (M-GND) on the MAIN board side B.

3. Set a disc. (YEDS-18)
4. Press the

button.

5. Check the oscilloscope waveform is as shown below.

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

RF Signal reference Waveform (Eye Pattern)

To watch the eye pattern, set the oscilloscope to AC range and
increase the vertical sensitivity of the oscilloscope for easy
watch-ing.

6. Stop revolving of the disc motor by pressing the

button.

7. SL801 is opened by taking the solder bridge.
