This adjustment is for assuring that compact discs will be placed in the center of the turntable.
<Adjustment Condition / Jig>
±
Power Supply Voltage : 13.2V
±
Test Disc : TCD-784M
<Adjustment Procedures>
1. Attach the adjusting screw to the upper chassis (See Figure 1.).
2. Insert the test CD (TCD-784M) into the disc No.1 position and play it.
3. After checking whether the disc is centered on the turntable, turn the adjusting screw unit it is in the center.
<Check Items>
±
Check that the disc is correctly centered.
±
Check that the disc is securely clamped.
±
Check that no abnormal noise is produced when clamping the disc.
