Well done scan of a useful manual. It will be useful in my workbench!!
 ;
Excelent scan job. It's a fully detailed service manual of this model.
HCD-DX50/RG80
Note : Clear RF signal waveform means that the shape � � � can be clearly distinguished at the center of the waveform.
Adjustment Location: [BD BOARD] (Conductor Side)
RF signal waveform VOLT/DIV : 200mV TIME/DIV : 500ns
level : 0.65 ±0.15Vp-p (RFDC) 1.1 ±0.4Vp-p (RFAC)

Procedure : 1. Connect an oscilloscope to TP (TEO) and TP (DVC). 2. Turn Power switch on. 3. Load a disc (LUV-P01) and playback the number nine track. 4. Press the gG button. (Becomes the 1 track jump mode.) 5. Confirm that the level B and A (DC voltage) on the oscilloscope waveform.
1 track jump waveform center of waveform B A (DC voltage) DVC level=1.0 ±0.5Vp-p symmetry

6. Adjust RV101 on the BD board so that the center of waveform becomes the same voltage of DVC. (i.e. A=0V)
