SAFETY PRECAUTION FOR SERVICE MANUALWARNINGS

THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASERCOMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR CLASS 1. THEREFORE IT ISIMPORTANTTHATTHE FOLLOWING PRECAUTIONS ARE OBSERVED DURING SERVICING TO PROTECT YOUR EYESAGAINST EXPOSURE TO THE LASER BEAM.l-WHEN THE CABINET IS REMOVED, THE POWER IS TURNED ON WITHOUT A COMPACT DISC IN POSITION AND THE

PICKUP IS ON THE OUTER EDGE THE LASER WILL LIGHT FOR SEVERAL SECONDS TO DETECT A DISC. DO NOTLOOK INTO THE PICKUP LENS.

P-THE LASER POWER OUTPUT OF THE PICKUP UNIT AND REPLACEMENT SERVICE PARTS ARE ALL FACTORYPRESET BEFORE SHIPMENT.DO NOT ATTEMPT TO READJUST THE LASER PICKUP UNIT DURING REPLACEMENT OR SERVICING.

3-UNDER NO CIRCUMSTANCES STARE INTO THE PICKUP LENS AT ANY TIME.4-CAUTION-USE OF CONTROLS OR ADJUSTMENTS, OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE

SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

OPERATION MANUAL

System Connections

n Setting the AC voltage selectorCheck the setting of the AC voltage selector located an the rear panel before plug-ging the unit into a wall so&et. If necessary, adjust the selector to correspond to theAC power voltage used I” your area.

Turn the selector with a screwdriver until the appropriate voltage num-ber appears in the window (110 V, 127 V, 220 V or 230 V - 240 V AC).

q Connecting the AC power leadAfter making all connections, plug the unit. If you plug the unit first,the unit will enter the demonstration mode.

Note:Unplug the AC power lea&from the wall socket if the unit will not be in use for a pro-longed period of time.

AC Plug AdaptorIn areas (or countries) where a wall socket as shown I” illustration Q is used, connectthe unit using the AC plug adaptor supplled with the urxt, as illustrated The AC plugadaptor IS not included in areas where the wall socket and AC power plug can bedirectly connected (see lllustratlon 0).

n Setting the FM/AM span selector

The International Telecommuntcatlon Union (ITU) has establlshed that member coun-trues should maintain either a 100 kHz or a 50 kHz interval between broadcasting fre-quencles of FM statons and 10 kHz or 9 kHz for AM station. The illustration showsthe 5019 kHz zones (regons 1 and 3), and the lOOI kHz zone (region 2)Before “sing the ““It, set the SPAN SELECTOR swtch (on the rear panel) to theInterval (span) Of your area

To change the tuning zone:1 Press the ON/STAN D-B,’ button to enter the stand-by mode.2 Set the SPAN SELECTOR switch (on the rear panel) as follows.

Since this CD system incorporates the following automaticadjustment functions, readjustment is not needed whenreplacing the pickup. Therefore, different PWBs and pickupscan be combined freely.Each time a disc is changed, these adjustments areperformed automatically. Therefore, playback of each disccan be performed under optimum conditions.

Items adjusted automatically(1) Offset adjustment (The offset voltage between the head

amplifier output and the VREF reference voltage iscompensated inside the IC.)

* Focus offset adjustment* Tracking offset adjustment

(2) Tracking balance adjustment (waveform drawingFig.14-2 EFBL)

NOTES ON SCHEMATIC DIAGRAMl Resistor:

To differentiate the units of resistors, such symbol as K andM are used: the symbol K means 1000 ohm and the symbolM means 1000 kohm and the resistor without any symbol isohm-type resistor. Besides, the one with “Fusible” is a fusetype.

. Capacitor:To indicate the unit of capacitor, a symbol P is used: thissymbol P means pica-farad and the unit of the capacitorwithout such a symbol is microfarad. As to electrolyticcapacitor, the expression “capacitance/withstand voltage”is used.(CH), (TH), (RH), (UJ): Temperature compensation(ML): Mylar type(P.P.): Polypropylene type

l Schematic diagram and Wiring Side of P.W.Board for thismodel are subject to change for improvement without priornotice.

9 The indicated voltage in each section is the one measuredby Digital Multimeter between such a section and the chas-sis with no signal given.1. In the tuner section,

indicates AMindicates FM stereo

2. In the main section, a tape is being played back.3. In the deck section, a tape is being played back.

( ) indicates the record state.4. In the power section, a tape is being played back.5. In the CD section, the CD is stopped.

l Parts marked with “A ” ( iI= = 17 ) are important formaintaining the safety of the set. Be sure to replace theseparts with specified ones for maintaining the safety andperformance of the set.

TROUBLESHOOTINGWhen the CD does not functionWhen the CD section does not operate when the objective lens of the optical pickup is dirty, this section may not operate. Cleanthe objective lens, and check the playback operation. When this section does not operate even after the above step is taken, checkthe following items.Remove the cabinet and follow the trouble shooting instructions..“Track skipping and/or no TOC (Table Of Contents) may be caused by build up of dust other foreign matter on the laser pickuplens. Before attempting any adjustment make certain that the lens is clean. If not, clean it as mentioned below.”

Turn off the power, and wipe the lens softly using a cleaning paper moistened with commercially available cleaning solution soas not to damage it. Be careful not to touch the lens with bare hands.

Dust gradually accumulates on the objective lens during use, and it may degrade performance. To avoid this problem, use acleaning disc designed for CD optical pickup lenses..

Parts code1. 1 CD optical pickup Lens cleaner disc 1 UDSKA0004AFZZ

1. Using the brush in the cleaner cap, apply 1 or 2 drops of th:e cleaning fluid to thebrush on the CD cleaner disc which has the mark next to it.

2. Place the CD cleaner disc onto the CD disc tray with the brush side down,thenpress the play button.

Cleaning fluid\

3. You will hear music for about 20 seconds and the CD player will automatically stop.If it continuous to turn, press the stop button.

l The CD lens cleaner should be effective for 30-50 operations, however if thebrushes become worn out earlier then please the cleaner disc.

0 If the CD cleaner brushes become very wet then wipe off any excess fluid with a softcloth.

0 Do not drink the cleaner fluid or allow it to come in contact with the eyes. In theevent of this happening then drink and/or rinse with clean water and seek medicaladvice.

0 The CD cleaner disc must not be used on car CD players or on computer CD-ROMdrives.

When a CD cannot be played1. “E-CD01 ” is displayed.

(1) Check the power to ICI (LC78645E), the presence of the clock signal (33.8688 MHz) and the status of the RESET terminal(pin 66 on ICI).

(2) Does the pickup move to the PICKUP-IN Switch (SW4) position?

If (1) and (2) are OK, check the system microcomputer (especially the communication line with the DSP).
