PRODUCT SAFETY NOTICE
Each precaution in this manua! should be followed during servicing. Components identified with the EC symbol A\ in
the parts list and the schematic diagram designate components in which safety can be of special significance. When
replacing a component identified with A\, use only the replacement parts 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.
SAFETY INTERLOCK
The Digital Compact Disc Player reads the disc signal by
detecting the taser beam. It must be avoided for the human body
to directly receive the beam. Especialy human eyes are badly
affected by the beam. Therefore, the unit is equipped with an
interlock to prevent the unnecessary laser outputs.
The laser outputs are controled by the injection or cutoff of the
constant voltage source to the laser diode with Pin 16 of IC 901
(«PD75206G). When Pin 16 is in “L” (Low) level, the laser emits
the beam. When Pin 16 is in “H” (High) level, the laser does not
emit the beam.
Pin 16 is set in “H” level when the unit is loaded with the disc
and it reads the index signals or when the unit is set in the play
mode after that. When the unit reads the index signals and the
following two conditions are met, the laser emits the beam.
1) When the Loading Limit Switch is set in “ON”. (The disc is
set to the turntable.)
2) The pickup is located at the area of the minimum internal
circumference.
After the above conditions are met and the index signals have
been read, the laser emits the beam when the following two
conditions are met.
1. When the PLAY button is pressed.
2. When the PLAY indicator is ON.

This unit uses a three beam
method for the laser pick-up.
Diffraction grid adjustment
involves adjusting the position of
the E and F beams in relation to
the main beam so that they are
in the same line.
4. Press the EJECT 1 button and place the test disc YEDS4 on
the table load. Press the PLAY button.
5. The waveform shown below is displayed six times on the
oscilloscope, Check that the p-p voltage is about 8V and that
the top and bottom of the waveform are symmetrical.

The following is the adjustment procedure. This is a precise
adjustment and must be made carefully.

4. Press the F FWD button. The TRACK No. indication is “2”
and the disc begins to rotate. Continue to press the PLAY
button. The unit is rotating in this state with the tracking
servo turned off.
5. Observe the resurge waveform of the waveform indicated on
the oscilloscope and insert the adjustment jig into the
diffraction grid holes to adjust the diffraction grid so that the
phase difference is 180°.
6. Even if the phase difference E
is 180° in the above step, the
& and F beams may be
mistakenly on two different
beam pit tines as shown
below. F

Be sure that the E and F beams are in the same pit line for
subsequent adjustments. 2
7. Remove the short between test pin TP1 and GND, and
TEST 1 and GND, and play back the fourth selection on
YEDS4.
8. Observe the waveform of the
signal between test pin E
and test pin F using the
dualtrace oscilloscope £

triggered. (100mV/DIV : 5«Sec/DiV)
When observation of the waveform is difficult, the trigger
level can be varied. When the beams are not in the same line,
return to step 1, and rotate the adjustment jig at the 180°
point. Confirm that the beams are in line at the 180° point.
Repeat steps 1 to 7 until confirmation of this is possible.
Note:
When the pick-up is replaced, it is adjusted as a unit, and
beams E and F can be brought in line and the phase made
180° by a slight adjustment. Slightly rotate the adjustment
jig when making adjustment. if the beams come out of line, it
is difficult to bring them back into the same pit fine.
ADJUSTMENT OF PICK-UP ANGLE
1. Mount the test disc YEDS4 on the turntable.
2. Turnon the power and play back the fourth selection.
3. Connect the oscilloscope between test pin HF and test pin
GND. Monitor the waveform of HF and rotate the angle
adjustment screw so that the waveform is at its maximum.

1. Turn on the power switch and mount test disc YEDS4 on the
table load. Set the unit to the STOP mode.
2. Short test pins TEST1 and GND of connector CN16.
3. Short test pin TP1 and test pin GND, and connect a DC
Voltmeter and oscilloscope to test pin TE of connector CN15
through the low-pass filter shown below.

4, Press the F FWD button. The TRACK No. indication is “2”
and the disc begins to rotate. Continue to press the PLAY
button. The unit is rotating in this state with the tracking
servo turned off.
5. Adjust P101 so that the DC Voltmeter and oscilloscope is
OV+15mvV.

ADJUSTMENT OF TURNTABLE HEIGHT
This adjustment must be made when the motor is replaced.
1. Attach the turntable so that
its top surface is 11.9mm _
from the top of the chassis. +

3. Turn on the power switch and playback the first selection on
test disc YEDS4.
4, Readjust the height of the turntable if the reading on the DC
Voltmeter is not in the range of OV+0.25V. (Increase the
height of the turntable when the OC Voltmeter reading is
positive, and decrease it when negative.)
ADJUSTMENT OF FOCUS/TRACKING GAIN
The measurement circuit shown below is necessary for
accurate adjustment of the focus and tracking gain. If this circuit
cannot be made, make adjustments using the simplified
procedure.
@ Remove connector CNS from
the pick-up and connect the
measurement circuit
between the PCB and = wmanece.

@ The iC used is TA7256P.
@ Volume — control 2k0-B

signal generator, and
adjustment is made for Pick-up

Simplified adjustment Procedure
® Focus gain adjustment
P102 is set to a mechanical
center.
e@ Tracking gain adjustment
P103 is set to a mechanical
center.
Precise adjustment procedure
@ Focus gain adjustment
1. Connect the measurement
circuit shown above, turn on
the power switch, and mount
the test disc YEDS4.
2. Playback the first selection
on the test disc, and apply a
1,000Hz 0.5Vp-p signal from
the signal generator.
3. Observe the resurge waveforms on the oscilloscope, and
adjust P102 so that the phase difference of outputs X and Y
from the measurement circuit is 90°.
@ Tracking gain adjustment
1. Adjustment is made in the
same manner as for focus
gain. The input from the
frequency generator is set to
1,000Hz, 0.5Vp-p, and P103
is adjusted so that the phase
difference is 90°.
