This manual is accurate and of high quality. It is only volume 2 of the service manual. This is schematic, parts lists, and exploded mechanical drawings. The theory of operation and the diss-assembly instructions are in volume 1. The unit can be tricky to dis-assemble portions of so the volume 1 manual can be important. The product description of the manual is accurate but it does not say anything about volume 1 and the image of the front page does clearly say Volume 2.

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:
