Sensor Adjustment Enter the adjustment mode and select “Mech Adjust” with the JOG dial, and press the dial. Press the GROUP 1 button to operate the loading mechanism, and continue pressing until the disc table locks. (Fig-3) Loosen the fixing screw and move the holder so that both PLAY button LED (green) and the ARTIST MODE button LED (green) light.
6-2. ELECTRICAL ADJUSTMENT Note: A clear RF signal waveform means that the shape “ ” can be clearly distinguished at the center of the waveform. Note: RF signal waveform CD Block is basically designed to operate without adjustment. Therefore, check each item in order given. VOLT/DIV : 200mV Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.
