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.

VARO ! Avattaessa ja suojalukitus ohitettaessa olet alttiina näkymättömälle lasersäteilylle. Älä katso säteeseen. VARNING! Osynlig laserstralning när denna del är öppnad och spärren är urkopplad. Betrakta ej strälen.

TRACKING OFF-SET ADJUST

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 Phantom, sound will also be heard from the surround speakers.)

Front (L, R) + centre + surround (monaural)

Front (L, R) + surround (monaural)

Front (L, R) + centre + surround (L, R)

● 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.

DOLBY DIGITAL

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.

• 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.

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.
