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.
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.

TAPE ADJUSTMENTS
1. Azimuth Adjustment
• Be sure to clean the heads before attempting to make any adjustment.
• Be sure both channels (1 and 2) are the same level.
(Using a dual-channel oscilloscope)
• Be sure both channel's waveform are same for the phase matching.
• After completion of the adjustment, use the threadlock (TB-1401B) to
secure the azimuth adjustment screws.
1. Remove the cover deck as Fig.1.
2. Load a test tape (VTT-738 etc. : 10kHz) in the Deck.
3. Press the PLAY button. (Normal playback)
4. Use a + 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. See Fig.1.
5. Press the PLAY button. (Reverse playback)
6. Use a + tip screwdriver to turn the screw for reverse azimuth
adjustment so that the left and right outputs are maximized
at the same phase during reverse playback.
7. Adjust so that the waveforms for the left and right channels are in alignment.

2. Tape Speed Adjustment
• Connect the Frequency Counter to TAPE OUT.
1. Insert the test tape (MTT-111N, etc.; 3,000Hz) into the DECK.
2. Press the PLAY button. .
3. Adjust a hole on the motor bottom so that a frequency counter reading of 3,000
±
5Hz is obtained.See Fig.2.
4. Press the STOP button, and eject the test tape.

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.
CAUTION: Regular type resistors and capacitors are not listed. To know those values, refer to the schematic diagram.
