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

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.
