SAFETY PRECAUTION FOR SERVICE MANUAL

WARNINGS

THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR CLASS 1. THEREFORE IT IS IMPORTANT THAT THE FOLLOWING PRECAUTIONS ARE OBSERVED DURING SERVICING TO PROTECT YOUR EYES AGAINST EXPOSURE TO THE LASER BEAM.

1-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 NOT LOOK INTO THE PICKUP LENS.

2-THE LASER POWER OUTPUT OF THE PICKUP UNIT AND REPLACEMENT SERVICE PARTS ARE ALL FACTORY

PRESET 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.

CAUTION

This Video CD Mini System is classified as a CLASS 1 LASER product.

The CLASS 1 LASER PRODUCT label is located on the rear cover.

Use of controls, adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. As the laser beam u sed in this compact disc player is harmful to the eyes, do not attempt to disassemble the cabinet. Refer servicing to qualified personnel only.

Connecting the AC power lead

Check the setting of the AC voltage selector located on the

rear panel before plugging the unit into an AC socket. If nec-

essary, adjust the selector to correspond to the AC power

voltage used in your area.

Selector adjustment:

Turn the selector with a screwdriver until the appropriate

voltage number appears in the window (110V, 127V, 220V

or 230V - 240V AC).

Notes:

Plug the AC power lead into an AC socket, after any con-

nections.

Unplug the AC power lead from the AC socket if the unit

will not be in use for a prolonged period of time.

AC Plug Adaptor

In areas (or countries) where an AC socket as shown in

illustration is used, connect the unit using the AC plug

adaptor supplied with the unit, as illustrated. The AC plug

adaptor is not included in areas where the AC wall socket

and AC power plug can be directly connected (see illustra-

tion ).

AM/FM interval (span)

The International Telecommunication Union (ITU) has

established that member countries should maintain either a

10 kHz or a 9 kHz interval between broadcasting frequen-

cies of any AM station. The illustration shows the 9 kHz

interval zones (regions 1 and 3), and the 10 kHz interval

zone (region 2).

Before using the unit, set the SPAN SELECTOR switch (on

the rear panel) to AM tuning interval (span) of your area.

To change the tuning zone:

1

Press the ON/STAND-BY button to enter the stand-

by mode.2Set the SPAN SELECTOR switch to "50/9" for 9 kHz

AM interval (50 kHz FM interval), and "100/10" for 10

kHz AM interval (100 kHz FM interval).3Whilst pressing down the button and the X-BASS/

DEMO button, hold down the ON/STAND-BY button

for at least 1 second.

"CLEAR AL" will appear.

Caution:

The operation explained above will erase all data stored

in memory including clock and timer settings, and tuner

and CD presets.

CD SECTION

• Adjustment

Since this CD system incorporates the following automatic adjustment functions, readjustment is not needed when replacing the pickup. Therefore, different PWBs and pickups can be combined freely. Each time a disc is changed, these adjustments are performed automatically. Therefore, playback of each disc can be performed under optimum conditions.

Items adjusted automatically

(1) Offset adjustment (The offset voltage between the head

amplifier output and the VREF reference voltage is compensated inside the IC.)

* Focus offset adjustment * Tracking offset adjustment

(2) Tracking balance adjustment (waveform drawing Fig. 15

EFBL)

(3) Gain adjustment (The gain is compensated inside the IC

so that the loop gain at the gain crossover frequency will be 0 dB.)

* Focus gain adjustment * Tracking gain adjustment

NOTES ON SCHEMATIC DIAGRAM

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

• Capacitor: To indicate the unit of capacitor, a symbol P is used: this symbol P means micro-micro-farad and the unit of the capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression “capacitance/withstand voltage” is used. (CH), (TH), (RH), (UJ): Temperature compensation (ML): Mylar type (P.P.): Polypropylene type

• Schematic diagram and Wiring Side of P.W.Board for this model are subject to change for improvement without prior notice.

• The indicated voltage in each section is the one measured by Digital Multimeter between such a section and the chassis with no signal given.

1. In the tuner section,

( ) indicates AM < > indicates 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.

• Parts marked with “ ” ( ) are important for maintaining the safety of the set. Be sure to replace these parts with specified ones for maintaining the safety and performance of the set.
