LASER BEAM SAFETY PRECAUTION
• Pick-up that emits a laser beam is used in this CD player section.
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.
LASER OUTPUT .............. 0.6 mW Max. (CW)
WAVELENGTH .................. 790 nm
• 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. Open the lid. And press the "Lid Close Key" 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. 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.
1. Azimuth Adjustment
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.

Description
LED Output Pin
Oscillator Input Pin
A resistor is connected to this pin to
determinc the oscillation frequency
Data Output Pin (N-Channel, Open-Drain)
This pin outputs scrial data at the falling
edge of the shift clock
(starting from the lower bit)
Data Input Pin
This pin inputs serial data at the rising cdge
of the shift clock (starting from the lower bit)
Clock Input Pin
This pin reads serial data at the rising cdge
and outputs data at the falling cdge.
Serial Interface Strobe Pin
The data input after the STB has fallen is
processed as a command.
When this pin "HIGH",CLK is ignored,
Key Data Input Pins
The data inputted to these pins are fatched
at the end of the display cycle.
