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 WITDOUT A COMPACT DISC IN POSITION AND THE

PICK-UP IS ON THE OUTER EDGE THE LASER WILL LIGHT FOR SEVERAL SECONDS TO DETECT A DISC. DO NOT
LOOK INTO THE PICK-UP LENS.

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

PRE-SET BEFORE SHIPMENT.

DO NOT ATTEMPT TO RE-ADJUST THE LASER PICK-UP UNIT DURING REPLACEMENT OR SERVICING.
3-UNDER NO CIRCUMSTANCES STARE INTO THE PICK-UP 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

Laser Diode Properties
Material: GaAIAs
Wavelength: 780 nm
Emission Duration: continuous
Laser Output: max. 0.6 mW

This Mini Component 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 used in this compact disc player is
harmful to the eyes, do not attempt to disassemble the
cabinet. Refer servicing to qualified personnel only.

CAUTION-INVISIBLE LASER RADIATION WHEN OPEN. DO NOT STARE INTO
BEAM OR VIEW DIRECTLY WITH OPTICAL INSTRUMENTS.

Remote control

Notes concerning use:

Replace the batteries if the operating distance is reduced or if

the operation becomes erratic.

Periodically clean the transmitter LED on the remote control

and the sensor on the main unit with a soft cloth.

Exposing the sensor on the main unit to strong light may in-

terfere with operation. Change the lighting or the direction of

AM/FM interval (span)

The International Telecommunication Union (ITU) has estab-

lished that member countries should maintain either a 10 kHz or

a 9 kHz interval between broadcasting frequencies 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.

2

Set 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).

3

Whilst pressing down the button and the

button, hold down the ON/STAND-BY button for at least 1

second.

Caution:

The operation explained above will erase all data stored in

memory including clock and timer settings, and tuner and CD

presets.

Notes:

1: Description of the "FM IF Adjustment" is not carried on this

Manual. It is because the IF coil in the FM front end section
has been best adjusted in the factory so that its further
adjustment is not needed at the field. When replacing the
FM front end assembly, no adjustment is needed either.

CD SECTION

Since this CD system incorporates the following automatic adjustment function, when the pickup is replaced, it is not necessary
to readjust it.
Since this CD unit does not need adjustment, the combination of PWB and laser pickup unit is not restricted.

• Automatic adjustment item

1. Focus offset (Fig. 11-2)

2. Tracking offset (Fig. 11-3)

3. E/F balance (tracking error balance) (Fig. 11-4)

4. RF level AGC function (HF level: constant)

5. RF level automatic follow-up of the tracking gain
This automatic adjustment is performed each time a disc is changed. Therefore,

each disc is played back using the optimal settings.

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.

TROUBLESHOOTING (CD SECTION)

When the CD does not function

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

Turn the power off.
Gently clean the lens with a lens cleaning tissue and a small amount of isopropyl alcohol.
Do not touch the lens with the bare hand.

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

HOW TO USE

1. Using the brush in the cleaner cap, apply 1 or 2 drops of the cleaning fluid to the brush 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, then press the play button.

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

CAUTION

The CD lens cleaner should be effective for 30 - 50 operations, however if the brushes become worn out earlier then please
replace the cleaner disc.
If the CD cleaner brushes become very wet then wipe off any excess fluid with a soft cloth.
Do not drink the cleaner fluid or allow it to come in contact with the eyes. In the event of this happening then drink and / or
rinse with clean water and seek medical advice.
The CD cleaner disc must not be used on car CD player or on computer CD ROM drives.
