This system conforms to Ver. 1.1 and Ver. 2.0 of

VIDEO CD standards. You can enjoy two kinds

of playback depending on the disc type.

About Multi Session CD

•This system can play Multi Session CDs when

an MP3 audio track is contained in the first

session. Any subsequent MP3 audio tracks

recorded in later sessions can also be played

back.

•This system can play Multi Session CDs when

a JPEG image file is contained in the first

session. Any subsequent JPEG image files

recorded in later sessions can also be played

back.

• If audio tracks and images in music CD format

or video CD format are recorded in the first

session, only the first session will be played

back.

Region code

Your system has a region code printed on the

back of the unit and will only play DVDs labeled

with the same region code.

DVDs labeled will also play on this system.

If you try to play any other DVD, the message

Notes about CD-R/CD-RW/DVD-R/DVD-RW

(Video mode)/DVD+R/DVD+RW

In some cases, CD-R/CD-RW/DVD-R/DVD-RW

(Video mode)/DVD+R/DVD+RW cannot be played

on this player due to the recording quality or physical

condition of the disc, or the characteristics of the

recording device and authoring software.

The disc will not play if it has not been correctly

finalized. For more information, see the operating

instructions for the recording device.

Note that discs created in the Packet Write format

cannot be played.

Music discs encoded with copyright

protection technologies

This product is designed to play back discs that

conform to the Compact Disc (CD) standard.

Recently, various music discs encoded with copyright

protection technologies are marketed by some record

companies. Please be aware that among those discs,

there are some that do not conform to the CD standard

and may not be playable by this product.

Note on playback operations

of DVDs and VIDEO CDs

Some playback operations of DVDs and VIDEO

CDs may be intentionally set by software

producers. Since this system plays DVDs and

VIDEO CDs according to the disc contents the

software producers designed, some playback

features may not be available. Also, refer to the

instructions supplied with the DVDs or VIDEO

CDs.

On handling discs

•To keep the disc clean, handle the disc by its

edge. Do not touch the surface.

•Do not stick paper or tape on the disc.

spray intended for vinyl LPs.

This system can only play back a standard

circular disc. Using neither standard nor circular

discs (e.g., card, heart, or star shape) may cause

a malfunction.

Do not use a disc that has a commercially

available accessory attached, such as a label or

ring.

SECTION 1

SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP

BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostatic

break-down because of the potential difference generated by the

charged electrostatic load, etc. on clothing and the human body.

During repair, pay attention to electrostatic break-down and also

use the procedure in the printed matter which is included in the

repair parts.

The flexible board is easily damaged and should be handled with

care.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused on

the disc reflective surface by the objective lens in the optical pick-

up block. Therefore, when checking the laser diode emission,

observe from more than 30 cm away from the objective lens.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead-

free mark (LF) indicating the solder contains no lead.

(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

• Unleaded solder melts at a temperature about 40 °C higher

than ordinary solder.

Ordinary soldering irons can be used but the iron tip has to be

applied to the solder joint for a slightly longer time.

Soldering irons using a temperature regulator should be set to

about 350 °C.

Caution: The printed pattern (copper foil) may peel away if

the heated tip is applied for too long, so be careful!

• Strong viscosity

Unleaded solder is more viscou-s (sticky, less prone to flow)

than ordinary solder so use caution not to let solder bridges

occur such as on IC pins, etc.

• Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder may

also be added to ordinary solder.

RELEASING THE DISC TRAY LOCK

The disc tray lock function for the antitheft of an demonstration

disc in the store is equipped.

Releasing Procedure :

Press two buttons of

A and x simultaneously for five seconds.

The message “UNLOCKED” is displayed and the tray is unlocked.

Note: When “LOCKED” is displayed, the tray lock is not released by turning

power on/off with the I/1 button.

NOTE OF REPLACING THE DMB07 BOARD

When replacing the DMB07 board, since the adjustment value is

not set up correctly, “Drive Auto Adjustment” can’t be performed.

In this case, initialize Memory in the following procedures.

Procedure:

1. Set the test mode. (See page 24)

2. Press the [2] ke y of the remote commander, and set the “DRIVE

MANUAL OPERATION”. (See page 28)

3. Press the [6] key of the remote commander, and set the “2-6,

Memory Check”. (See page 30)

4. Press the [CLEAR] key of the remote commander , and initialize

Memory.

Connection:

Procedure:

1. Connect an oscilloscope to test point 1 pin and 3 pin of

CN901 on the DMB07 board.

2. Turn the power on.

3. Put the disc (LUV-P01) (Part No.: 4-999-032-01) (CD) in to

playback.

4. Confirm that oscilloscope waveform is clear and check RF

signal level is correct or not.

5. Put the disc (TDV -520CSO) (P art No.: J-2501-236-A) (DVD)

is to playback.

6. Perform confirmation in the same manner as step 4.

Note: A clear RF signal waveform means that the shape “◊” can be clearly

distinguished at the center of the waveform.
