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

● 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.

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. 14-2)

2. Tracking offset (Fig. 14-3)

3. E/F balance (tracking error balance) (Fig. 14-4)

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.

When you connect this unit to a DVD player which is playing
a disc with the trademark, you can enjoy
realistic, powerful sound by playing back the recorded signal
through 6 speakers with the sound coming from the front
left, front right, centre, surround left, surround right and sub
woofer speakers.

To listen to a disc using the Dolby Digital mode:

1

Connect a DVD player. (See page 39.)

2

Press the DVD 1/VCR 1 or DVD 2/VCR 2 button to select
"DVD 1" or "DVD 2".

3

Start the DVD player.

Note:

● When the Dolby Digital surround mode is being used, the
equalizer will be set to FLAT.

Type of Dolby digital signal

There are different types of Dolby digital signals. The type of Dolby digital signal being input into this unit can be checked
in the display.

Display Channels available Display Channels available

Normal PCM playback Front (L, R) + surround

(L, R)

Centre only (monaural) Front (L, R) + centre

Front (L, R)
(When the surround mode
is set to Normal or

heard from the surround
speakers.)

● If a low frequency sound effect (Low Frequency Effect) contains a Dolby digital signal, "LFE" will light in the display.
When this "LFE" is lit, low frequency signals will be output from the sub woofer.

SURROUND EFFECT CONTROL

This product allows you to enjoy 4 surround modes.

Normal mode:

When you play a sound source that has the
(5.1 channels) or trademarks, you can enjoy
surround sound using all 6 speakers.

Phantom mode:

When you play a sound source that has the
or trademarks, you can enjoy surround sound
using 5 speakers, but not the centre speaker.

Virtual Dolby Surround:

You can enjoy a three-dimensional surround stereo image
using just the 2 front speakers.

Enhanced Virtual Surround:

You can enjoy surround sound, using only the 2 front
speakers, but this mode increases the three-dimensional
stereo image effect even more.

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.
