7 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.
