NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
break-down because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
Carry out the “S curve check” in “CD section adjustment” and
check that the S curve waveforms is output three times.

TEST MODE
[MC Cold Reset]
• The cold reset clears all data including preset data stored in the
RAM to initial conditions. Execute this mode when returning
the set to the customer.
Procedure:
1. Turn the power ON or set to the DEMO mode.
2. Press three buttons of x (TC-B) , TUNER ENTER , and \/1
simultaneously.
3. The set is reset, and displays “COLD RESET”, then becomes
DEMO mode.
[Change-over the AM Tuning Interval]
• The AM tuning interval can be changed over 9 kHz or 10 kHz.
Procedure:
1. Press the \/1 button to turn the power ON.
2. Select the function “TUNER”, and press the TUNER/BAND
button to select the BAND “AM”.
3. Press the \/1 button to turn the power OFF.
4. Press the ENTER and \/1 buttons simultaneously,
and the display on the fluorescent indicator tube changes to
“AM 9 K STEP” or “AM 10 K STEP”, and thus the tuning
interval is changed over.
[CD Ship Mode] (No memory clear)
• This mode moves the optical pick-up to the position durable to
vibration. Use this mode when returning the set to the customer
after repair.
Procedure:
1. Press the \/1 button to turn the power ON.
2. Press the EDIT and
3. A message “LOCK” is displayed on the fluorescent indicator
tube, and the CD delivery mode is set.
[LED and Fluorescent Indicator Tube All Lit, Key Check
Mode]
Procedure:
1. Press three buttons of x (TC-B) , TUNER ENTER ,and
DISC 2 simultaneously.
2. LEDs and fluorescent indicator tube are all turned on.
3. Press the DISC 1 button, the MODE and DESTINATION are
displayed fluorescent indicator tube.
4. Each time the DISC 1 button is pressed, the MC/GC category
version is displayed in the following order.
5. Press the DISC 2 button, and the key check mode is acti-vated.
NR MC GC CD CDDM CDMA
6. In the key check mode, the fluorescent indicator tube displays
“K 0 J0 V0”. Each time a button is pressed, “K” value in-creases
to “K69”call the button is pressed.However, once a button is
pressed, it is no longer taken into account.
“V” value increases like 1, 2, 3 ... if turn the VOLUME dial
clockwise (“+” direction), or it decreases like 0, 9, 8 ... if turn
the VOLUME dial counterclockwise (“–” direction).
7. To release from this mode, press three buttons in the same
manner as step 1, or disconnect the power cord.

[Sled Servo Mode] (CD service mode)
• This mode can run the CD sled motor freely. Use this mode, for
instance, when cleaning the pick-up.
Procedure:
1. Select the function “CD”.
2. Press three buttons x (TC-B) , TUNER ENTER , and
DISC 5 simultaneously.
3. The Sled Servo mode is selected, if “CD” is blanking on the
fluorescent indicator tube.
4. With the CD in stop status, press M button in CD section to
move the pick-up to outside track, or m button to inside track.
5. To exit from this mode, press
OFF.
Note:
• Always move the pick-up to most inside track when exiting from
this mode. Otherwise, a disc will not be unloaded.
• Do not run the sled motor excessively, otherwise the gear can
be chipped.
[Change-over of FUNCTION Name]
• The FUNCTION name of external input terminal can be changed
over to VIDEO or MD. W ith the FUNCTION selected to “MD”,
about 5dB mute is applied to the input gain.
Procedure:
1. Press \/1 button to turn the power OFF.
2. Press
several seconds, and the power is turned on, the display of
fluorescent indicator tube changes to “MD” or “VIDEO”
instantaneously, and thus the FUNCTION is changed over.
[Aging Mode]
This mode can be used for operation check of tape deck section.
Tape deck section work in parallel.
• If an error occurred:
The aging operation stops and display then status.
• If no error occurs:
The aging operation continues repeatedly.
Procedure:
1. Load the tapes into the decks A and B respectively.
2. Press the FUNCTION button to select the function “CD”.
3. Press the PLAY MODE button to set the “ALL DISCS” mode,
and press the REPEAT button to “REPEAT” off.
4. Press three buttons of x (TC-B) , TUNER ENTER ,and
DISC 4 simultaneously.
5. The aging mode is activated, if the indicator of disc tray number on the fluorescent indicator tube is blinking.
6. To release from the aging mode, press the \/1 button to turn
the power OFF and operate the cold reset. (Refer to the “MC
Cold Reset”)

MECHANICAL ADJUSTMENTS
Precaution
1. Clean the following parts with a denatured alcohol-moistened
swab:
record/playback heads pinch rollers
erase head rubber belts
capstan idlers
2. Demagnetize the record/playback head with a head demagnetizer.
3. Do not use a magnetized screwdriver for the adjustments.
4. After the adjustments, apply suitable locking compound to the
parts adjusted.
5. The adjustments should be performed with the rated power supply voltage unless otherwise noted.

Precaution
1. Demagnetize the record/playback head with a head demagnetizer.
2. Do not use a magnetized screwdriver for the adjustments.
3. After the adjustments, apply suitable locking compound to the
parts adjust.
4. The adjustments should be performed with the rated power
supply voltage unless otherwise noted.
5. The adjustments should be performed in the order given in
this service manual. (As a general rule, playback circuit
adjustment should be completed before performing recording
circuit adjustment.)
6. The adjustments should be performed for both L-CH and R-CH.
7. Switches and controls should be set as follows unless otherwise specified.
8. Set to the DOLBY NR OFF.
9. Set to the test mode.
(1) Press the \/1 button to turn the power ON.
(2) Select the function “TAPE A or B”.
(3) Press the button of x (TC-B) , ENTER ,and DISC 3
simultaneously, to set the tape deck test mode
and displays “TEST MODE” on the fluorescent indicator
tube.
(4) To release from the test mode, press the \/1 button.

CD SECTION
Note :
1. CD Block is basically designed to operate without adjustment.
Therefore, check each item in order given.
2. Use LUV-P01 (4-999-032-01) unless otherwise indicated.
3. Use an oscilloscope with more than 10M impedance.
4. Clean the object lens by an applicator with neutral detergent
when the signal level is low than specified value with the
following checks.
S-Curve Check

TP(FE)
TP(DVC)
Procedure :
1. Connect oscilloscope to TP (FE).
2. Connect between TP (FE) and TP (DVC ( 1.65 V) by lead
wire.
3. Press the \/1 button to turn the power ON.
4. Load a disc (LUV -P01) and actuate the focus search. (In consequence of open and close the disc tray, actuate the focus search)
5. Confirm that the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 2
±0.5 Vp-p.
