CD PLAYER ADJUSTMENT PROCEDURES
BEFORE CHECKING OR ADJUSTING CD
PLAYER
1. Procedures for all adjustments for the CD player from atart
to finish are described below.
2. The pick-up does not have to be adjusted if everything has
been checked and no problems were found.
CHECKING FOCUS ERROR SIGNAL
The effectiveness of the pick-up is determined by checking its fo-
cus error signal. This must be checked before any repairs are
performed on the CD player.
1. Apply Power Switch to the set and press the STOP button.
2. Short test terminal (CN15) TOFF pin to GND to turn the
tracking servo OFF.
3. Connect the oscilloscope to test point TP12 (focus
error) pinandto GND.
(Set the time at 0.5 Sec/DIV.)
4. Press the OPEN/CLOSE button, place the test disc on
the table load, and then press the OPEN/CLOSE but-
ton once again.
5. Once the disc is set, awaveform like that shown in
the illustration below will be repeated three times.
Check that the p-p voltage of this waveform is the
same above and below the horizontal axis at 3V.

Press the OPEN/CLOSE button repeatedly to pull out
and Insert the disc until the waveform appears each
time the disc is inserted and removed.
If the resuits of the above procedure are not satis-
factory, the pick-up is damaged.
FREE RUN FREQUENCY ADJUSTMENT
1. Connect the frequency counter to VCO test terminal
(CN5) PCK test pin and to GND, (Use a10:1 probe.)
2. Short the test point TP4 (OSC ON) pin to GND.
3. Apply Power Switch to the set and press the STOP
button.

Measurement circuit
Apply Power Switch to the set and PLAY the first item on
the disc.
If the DC Voltmeter reading is not in the ranges OV&O.2V
for inner tracks and OV+-O.35V for outer tracks, then the
turntable height must be readjusted. Raise the turntable
higher if the DC Voltmeter indicator is on the plus (+)
side, and lower it if it is on the minus (–) side.
(With this circuit lV represents movement of approxi-
mately 0.55mm -0.65mm.)
DIFFRACTION GRID ADJUSTMENT
This set uses athree-beam laser pick-up system. Adjusting
the diffraction grid means adjustment so that beams Eand F
are in position with respect to the main beam as shown in the
diagram below on the bit streams.
The adjustment procedure involves arranging the three
beams in astraight line along the same bit stream and then
adjusting them to specified positions.
The adjustment steps are detailed below. These are very
adjustments so great care should be exercised in this.

Apply Power Switch to the set and press the STOP button.
Short test point TP2 (TEST) pinto the GND, and then ehort
)est terminal (CN15) TOFF pin to GND to turn the tracking
servo OFF.
In this state, connect the E-beam output of test terminal
(CN15) to Channel 1of the oscilloscope and F-beam out-
put of test terminal (CN15) to Channel 2, and now observe
the Iissajous waveform on the oscilloscope.
Place the test disc YEDS7 on the table load, and press the
PLAY button.
When the disc begins to rotate awaveform will appear
on the oscilloscope. While observing this waveform,
move the Linear Motor in the direction of the arrow by
hand to send the pick-up to the outer edge.
ection of
k-up motion
When the pick-up approaches the outer edge, the wave-
form on the oscilloscope will suddenly disappear, and if
it is now pushed further outwards there will be points at
which waveforms will appear again. These locations are
the multiburst signal storage locations, If the disc rotates
at high speed at this time, perform this step once again.
Set the oscilloscope to X-Y operation to bring up the
waveforms. Insert the adjustment tool in the diffraction
grating adjustment hole on the pick-up, and rotate the
adjustment tool to right and left. The waveform should be
almost astraight line with aphase difference of 0° as
shown in Fig. 3below. This indicates that the beams are
arranged in one straight line. The waveform in Fig. 4in-
dicates that the beams are not arranged along the same
stream.
Fig. 3Fig. 4

NOTE:
It is important to turn the adjustment tool only alittle at a
time. If It Is rotated too far, the beams will be pushed over
into neighboring streams.

Next, when the waveform in Fig. 3is obtained, turn the
adjustment tool clockwise from that position at which the
waveform in Fig. 3appeared and adjust so that the
waveform is astraight line with aphase difference of
180°. (See Fig. 5)
Fig. 5
Once the state indicated by the waveform in Fig. 5is ob-
tained, hold the STOP button down temporarily, and re-
move the connection between test point TP2 (TEST) pin
and the GND as well as that between test terminal (CN15)
TOFF pin and GND.
Next, press the PLAY button, and set the oscilloscope in
the DUAL MODE so that both Eand Foutputs can be seen.
Set the DISPLAY TIME to 51JS.Now, adjustment is com-
plete if the waveforms shown below In Fig. 6(Channel 1
trigger) are obtained.

NOTE:
Diffraction grating adjustment is performed for asingie
pick-up, so if the following checks are performed adjust-
ment is unnecessary.
a, PLAY the fourth item on the test disc (Modern Wave
HCA35-1045, Toshiba-EMl), turn the tracking servo
OFF, and check that the waveform is linear with a
phase difference of 180°.
b, Next, apply tracking servo, and if the waveforms
shown in Fig. 6are obtained then adjustment Is un-
necessary.

CAUTION ON RF ADJUSTMENT
This model uses amicroprocessor for memory preset control for the various bands.
This function has been used to preset frequency points for the different bands to permit adjustment and make it
possible to check the function of the microprocessor. To use this supplemental function, ground initialize point
jumper wire JM826 for 1second before beginning adjustment. The following table shows the initially preset fre-
quencies.
NOTE: If the AM tuning cannot be obtained properly, then cut off the jumper wire JP801 (located near the connector
CN802). 10kHz step will be set (factory adjusted to 9kHz position).

SYSTEM CLOCK ADJUSTMENT
Since this adjustment sets standard time for the total system, be sure to adjust before operation,
1. Connect the TP811 to the ground (The FL indicator goes out.)
2. Connect the Frequency Counter between the TP81O and ground.
3. Adjust the TC804 until the Frequency Counter reads 65,536kHz *0.1 Hz.
(Avoid the minus “ -” disparity as much as possible in case the clock lags behind.)
4. After the adjustment, Disconnect the TP811 from the ground and the original mode is returned.

CASSETTE DECK ELECTRICAL ADJUSTMENT
BEFORE ADJUSTMENT
Itthe tape surface which contacts the head, the capstan, and
thepinch roller, etc., isstained, itwillcause untable running
of the tape, wow and flutter, imperfect recording and erasing,
deterioration of tonal quality, and the tape jam around the
capstan, etc. Occasionally clean each part as follows;
1. Cut off power
2. Open the cassette lid.
3. Wipe the head, the capstan, and the pinch roller with a
cotton swab. If they are excessively stained, clean them
with the swab soaked in absolute alcohol or cleaning liq-
uid on the market.

PRODUCTSAFEN NOTICE
Each precaution in this manual should be followed during servic-
ina. Components identified with the IEC symbol ~In the parts list
an~ the schematic diagram designate components in which safety
can be of special significance. When replacing acomponent iden-
tified with ~, 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 re-
sistance measurements must be made to determine that exposed
parts are acceptably insulated from the supply circuit before re-
turning the product to the customer.
