CD SECTION
0 dB = 0.765V Procedure: 1. Connect the oscilloscope to the test point TP601(RF) on the MAIN board. 2. Set a disc. (YEDS-18) 3. Press the u button. 4. 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.
The CD section adjustments are done automatically in this set. Precautions for Check 1. Perform check in the order given. 2. Use YEDS-18 disc (Part No.: 3-702-101-01) unless otherwise indicated. 3. Power supply voltage requirement :DC4.5 V in DC IN jack. (J401) VOLUME button : Minimum HOLD switch : OFF RF Level Check Condition: � Hold the set in horizontal state. Connection:
