•Pick-up that emits a laser beam is used in this CD player section.

CAUTION :

USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE

OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN

MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

THIS PRODUCT SHOULD NOT BE ADJUSTED OR REPAIRED BY

ANYONE EXCEPT PROPERLY QUALIFIED PERSONNEL.

WAVELENGTH .................. 790 nm

CD PICK-UP MAINTENANCE

About pick-up (Optical lens) Cleaning

Clean a lens with swab of the cotton which moistened it with alcohol, cleaning paper or cleaning disc appointed.

Specified cleaning disc : LC-1 (Part code : 645 026 1961 ..... manufactured by SANYO.)

Show a clean procedure in the following in reference by swab of cotton.

1. Cotton swab is wrapped with Cleaning paper.

2. Add the isopropyl alcohol.

3. Gently move the tip of cotton swab just like a draw a whirlpool from inside to outside on the surface of lens.

CD PLAYER ADJUSTMENTS

1. ADJUSTMENTS

(1) Confirm the tracking balance

1. Turn on the POWER switch.

2. Connect an Oscilloscope to TP2 (TE) and TP4 (VC).

3. Set the test disc.

4. Press "PLAY" button to turn into the "PLAY" mode.

5. Keep holding "SKIP" button down so as to be "SERCH"

mode, then confirm that the oscilloscope waveform is

symmetrical on the top and bottom in relation to 0V (VC).

a. Replacing the head

1. After replacement, demagnetize the heads by using

a degausser.

2. Be sure to clean the heads before attempting to make

any adjustments.

3. Be sure both channels (1 and 2) are the same level.

(Using a dual-channels oscilloscope).

4. All wiring should be returned to the original position

after work is completed.

b. Adjusting head azimuth

1. Load a test tape (VTT-738, etc. :10kHz) for

azimuth adjustment.

2. Press the PLAY button.

3. Use a cross-tip screwdriver to turn the screw for

normal azimuth adjustment so that the left and right

outputs are maximized at the same phase during

normal playback.

4. Press the STOP button.

MOTOR SPEED

ADJUSTMENT

d. Replacing the moto

c. Adjusting motor speed

1. Insert the test tape (MTT-111 or etc. 3,000 Hz).

2. Press the PLAY button.

3. Use a flat-tip screwdriver to turn the SVR to adjust so

that the frequency counter becomes 3,000 Hz.

4. Press the STOP button.

e. Checking the mechanism torques

• Clean the head, capstan and pinch roller before making

any measurement.

1. Switch "ON" the POWER.

2. Connect an oscilloscope to TP1 (RF) and TP4 (VC).

3. Load the test disc.

4. Press the PLAY button.

5. Check to be sure that the "eye" pattern is at

the center of waveform and that the diamond

shape is clearly defined.

6. Press the STOP button.

special significance. When replacing a component identified by !

!! , use only the replacement parts designated, or parts with the same ratings of resistance, wattage or voltage that are designated in the parts list

in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably insulated from the supply circuit before returning the product to the customer.
