9 CD DISC CENTERING ALIGNMENT
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-792A
• •
<Adjustment Procedures>
1. Attach the adjusting screw to the upper chassis (See Figure 1.).
2. Insert the test CD (TCD-792A) 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.
• •
[Directions of Turning the Adjusting Screw]
CD stops before its proper position : Turn the screw counterclockwise.
• •
CD overruns : Turn the screw clockwise.
• •
4. After the adjustment, lock the screw.
