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

CAUTION :
THIS PRODUCT CONTAINS A LOW POWER LASER DEVICE,
TO ENSURE CONTINUED SAFETY DO NOT REMOVE ANY
COVERS OR ATTEMPT TO GAIN ACCESS TO THE INSIDE
OF THE PRODUCT.
REFER ALL SERVICING TO QUALIFIED PERSONNEL.

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

Power supply
(VCC1, short-circuit 1pin)
Active on the positive going edge to sample all inputs.
Disables or enables device operation by masking or enabling all inputs except CLK,CKE
and L(U)DQM.
Makes system clock to freeze operation from the next clock cycle.
CKE should be enabled at least one cycle prior to new command.
Disable input buffers for power down in standby.
Row / column addresses are multiplexed on the same pins.
Row address : RA0~RA10, column address : CA0~CA7
Selects bank to be activated during row address latch time.
Selects bank for read/write during column address latch time.
Latches row addresses on the positive going edge of the CLK with RAS low.
Enables row access & precharge.
Latches column addresses on the positive going edge of the CLK with CAS low.
Enables column access.
Enables write operation and row precharge.
Latches data in starting from CAS, WE active.
Makes data output Hi-Z tSHZ after the clock and masks the output.
Blocks data input when L(U)DQM active.
