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 DECKEL GEÖFFNET UND WENN SICHERHEITSVERRIEGELUNG ÜBERBRÜCKT IST. NICHT, DEM STRAHL AUSSETZEN.

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.2.

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

Fig.1

NORMAL

2. Tape Speed Adjustment

• Connect the Frequency Counter to TAPE OUT.

1. Insert the test tape (MTT-111N, etc.; 3,000Hz) into the DECK.

MOTOR

hole for adjustment

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.
