LASER BEAM SAFETY PRECAUTION

•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

LASER OUTPUT.......... 0.6 mW Max. (CW)

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

CAUTION – INVISIBLE LASER RADIATION WHEN OPEN AND

INTERLOCKS DEFEATED. AVOID EXPOSURE TO BEAM.

ADVARSEL – USYNLIG LASER STRÅLING VED ÅBNING, NÅR

SIKKERHEDSAFBRYDERE ER UDE AF FUNKTION, UNDGÅ UDS ÆTTELSE

FOR STRÅLING.

VARNING – OSYNLIG LASER STRÅLNING NÄR DENNA DEL ÄR ÖPPNAD

OCH SPÄRR ÄR URKOPPLAD. STRÅLEN ÄR FARLIG.

VORSICHT – UNSICHTBARE LASERSTRAHLUNG TRITT AUS, WENN

TAPE ADJUSTMENTS

•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.2.

5. Adjust so that the waveforms for the left and right channels are in alignment.

1. Azimuth Adjustment

3. Torque Measurement

2. Tape Speed Adjustment

NORMAL

• 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.3.

4. Press the STOP button, and eject the test tape.
