10 ALIGNMENT POINTS

Balance, Fader Control : center

Bass, Treble Control : Center

Dolby NR: OFF

11 CD DISC CENTERING ALIGNMENT

This adjustment is for assuring that compact discs will be placed in the center of the turntable.

Power Supply Voltage : 13.2V

Test Disc : TCD-792A

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 that the disc is correctly centered.

Check that the disc is securely clamped.

Check that no abnormal noise is produced when clamping the disc.

HONDA / CQ-EH8160AK

[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.
