SAFETY CHECK-OUT(US model only)
After correcting the original service problem, perform thefollowing safety checks before releasing the set to the customer:Check the antenna terminals, metal trim, “metallized” knobs, screws,and all other exposed metal parts for AC leakage. Check leakage asdescribed below.
LEAKAGE
The AC leakage from any exposed metal part to earth ground andfrom all exposed metal parts to any exposed metal part having areturn to chassis, must not exceed 0.5 mA (500 microampers).Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCAWT-540A. Follow the manufacturers’ instructions to use theseinstruments.
2. A battery-operated AC milliammeter. The Data Precision 245digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of aVOM or battery-operated AC voltmeter. The “limit” indicationis 0.75 V, so analog meters must have an accurate low-voltagescale. The Simpson 250 and Sanwa SH-63Trd are examples ofa passive VOM that is suitable. Nearly all battery operateddigital multimeters that have a 2V AC range are suitable. (SeeFig. A)

This appliance is classified as a CLASS 1 LASER product. TheCLASS 1 LASER PRODUCT MARKING is located on the rearexterior.
Laser component in this product is capableof emitting radiation exceeding the limit forClass 1.
CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous radiationexposure.
Notes on chip component replacement• Never reuse a disconnected chip component.• Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing• Keep the temperature of soldering iron around 270˚C
during repairing.• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).• Be careful not to apply force on the conductor when soldering
or unsoldering.
NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostaticbreak-down because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.The flexible board is easily damaged and should be handled withcare.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused onthe disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission,observe from more than 30 cm away from the objective lens.

[Cold Reset]• The cold reset clears all data including preset data stored in the
RAM to initial conditions. Execute this mode when returningthe set to the customer.
Procedure:1. Press three buttons STOP , DISPLAY , and DISC 1
simultaneously.2. The fluorescent indicator tube becomes blank instantaneously,
and the set is reset.
[Tuner Step Change] (Except for European and Middle Easternmodels)• A step of AM channels can be changed over between 9 kHz and
10 kHz.Procedure:1. Press POWER button to turn the set ON.2. Select the function “TUNER”, and press TUNER/BAND button
to select the BAND “AM”.3. Press POWER button to turn the set OFF.4. Press ENTER and POWER buttons simultaneously, and the
display of fluorescent indicator tube changes to “AM 9 k STEP”or “AM 10 k STEP”, and thus the channel step is changed over.
[Function Change Mode]• Select either VIDEO or MD of the external FUNCTION input.Procedure:1. Turn on the power.2. Hold down MD(VIDEO) button then press POWER button,
and release POWER button first in order not in switch off theset immediately.The another function of the previous function is selected, theinput level is also changed and displayed “MD” or “VIDEO”.
[GC Test Mode]• This mode is used to check the software version, FL tube, LED,
keyboard and VACS.Procedure:1. Press three buttons STOP , DISPLAY , and DISC 2
simultaneously.2. LEDs and fluorescent indicator tube are all turned on.3. When you want to enter the software version display mode,
press DISC 1 .The model number and destination are displayed.4. Each time DISC 1 is pressed, the display changes stating from
MC version, GC version, CD version, CDDM, CDMA, CDMB,BDA, BDB, ST version, TA version, TM version, TC version,in this order, and returns to the model number and destinationdisplay.
5. When DISC 3 is pressed while the version numbers are beingdisplayed except model number and destination, year, monthand day of the software creation appear. When DISC 3 is pressedagain, the display returns to the software version display. WhenDISC 1 is pressed while year, month and day of the softwarecreation are being displayed, the year, month and day of creationof the software versions are displayed in the same order ofversion display.
6. Press DISC 2 button, and the key check mode is activated.7. In the key check mode, the fluorescent indicator tube displays
“KOJOVO”. Each time a button is pressed, “KEY” valueincreases.However, once a button is pressed, _it is no longer taken intoaccount.“VOL” value increases like 1, 2, 3...if rotating VOLUME knobin “+” direction, or it decreases like 0, 9, 8...if rotating in“_”direction.
8. Also when DISC 3 is pressed after lighting of all LEDs and FLtubes, value of VACS appears.
9. To exit from this mode, press three buttons in the same manneras step 1, or disconnect the power cord.
[MC Test Mode]• This mode is used to check operations of the respective sections
of Amplifier, Tuner, and Tape.Procedure:• To enter MC Test Mode1. Press the POWER button t turn on the set.2. Press the three buttons of STOP , DISPLAY and DISC 3
simultaneously.3. Cursor segment flash on the FL display tube. The input
FUNCTION is changed to GAME.

1. When the VOLUME control knob is turned clockwise evenslightly, the sound volume increases to is maximum and amessage “VOLUME MAX” appears for two seconds, then thedisplay returns to the original display.
2. When the VOLUME control knob is tuned counter-clockwiseeven slightly, the sound volume decreases to its minimum and amessage “VOLUME MIN” appears for two seconds, then thedisplay returns to the original display.
* Tuner function1. In the test mode, the default-preset channel is called even when
the TUNER is selected and an attempt is made to call the presetchannel that has been stored in memory. (It means that thememory is cleared.)
2. The minimum, center and maximum frequency of each band isset then.
* Tape recording test1. To enter the MC Test Mode.2. Load tapes in both tape decks A and B.3. Press the REC button to start recording.4. Pressing the M/+ , m/– buttons during recording returns
the tape to the recording start position and stops it at this position.5. Pressing the “High Speed Dubbing” key while playing back the
tape of deck B switches the playback speed between “NormalSpeed” and “High Speed”.
Note:When the playback direction of the tape is set to other than “ONYWAY”, the restriction on the number of times playback which canbe repeated will be cleared.
* AMS Test Mode1. Set TAPE function2. Select the desired loop by pressing the PLAY MODE button.
Insert a test tape AMS-110A or AMS-120 to Deck A.3. Press the SPECTRUM (or KARAOKE PON )button to enter
the AMS test mode.4. After a tape is rewound first, the FF AMS is checked, and the
mechanism is shut off after detecting the AMS signal the AMSsignal twice.
5. Then the REW AMS is checked and the mechanism is shut offafter detecting the AMS signal twice.

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 10MΩ impedance.4. Clean the object lens by an applicator with neutral detergent
when the signal level is low than specified value with thefollowing checks.
S-Curve Check
Procedure :1. Connect oscilloscope to TP (FE).2. Connect between TP (FE) and TP (DVC ( 1.65 V) by lead
wire.3. Turn Power switch on.4. Load a disc (LUV-P01) and actuate the focus search. (In
consequence of open and close the disc tray, actuate the focussearch)
5. Confirm that the oscilloscope waveform (S-curve) issymmetrical between A and B. And confirm peak to peak levelwithin 2 ±0.5 Vp-p.
6. After check, remove the lead wire connected in step 2.Note : • Try to measure several times to make sure than the ratio
of A : B or B : A is more than 10 : 7.• Take sweep time as long as possible and light up the
brightness to obtain best waveform.
RF Level Check
Procedure :1. Connect oscilloscope to TP2 (RFDC) and TP1 (RFAC).2. Turned Power switch on.3. Load a disc (LUV-P01) and playback.4. Confirm that oscilloscope waveform is clear and check RF signal
level is correct or not.
