Special Component Notice

The components identiﬁ ed by mark 9 contain conﬁ dential infor- mation. Strictly follow the instructions whenever the components are repaired and/or replaced.

SAFETY-RELATED COMPONET WARNING!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

HCD-DZ265K/DZ266K/DZ270K/DZ570K/DZ777K

Laser component in this product is capable of emitting radiation exceeding the limit for Class 1.

This appliance is classiﬁ ed as a CLASS 1 LASER product. This marking is located on the rear or bottom exterior.

CAUTION

Use of controls or adjustments or performance of procedures other than those speciﬁ ed herein may result in hazardous radiation exposure.

Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

Flexible Circuit Board Repairing

• Keep the temperature of soldering iron around 270 °C during

repairing.

• Do not touch the soldering iron on the same conductor of the

circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering

or unsoldering.

About This Operating Instructions

• The instructions in this Operating Instructions describe the controls on the remote. You can also use thecontrolsonthe unit if they have the same or similar names as those on the remote.

• The Control M enu items may var y depending on the area.

• “DVD” may be used as a general term for a DVD VIDEO, D VD+RW /DVD+R, and DVDRW/DVD-R.

• Measurements are expressed in feet (ft) for North American models.

• The defau lt setting is underlined.

About the S-AIR function

The system is compatible with the S-AIR function, which allows transmission of sound between S-AIR products wirelessly. The following S-AIR products can be used with the system:

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the leadfree 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 viscous (sticky, less prone to ﬂ ow)

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.

• Surround amplifier: You can enjoy surround speaker sound wirelessly.

• S-AIR receiver: You can enjoy system sound in another room.

These S-AIR products can be purchased as an option (the S-AI R product lineup differs depending on the area).

Notes or instructions for the surround amplifier or S -AIR receiver in this operating instructions refer only to when the surround amplifier or S-AIR receiver is used. For details on the S-AIR function, see “Using an S-AIR Product” (page 83).

Example of discs that the system cannot play

The system cannot play the following discs:

• CD -ROM/CD-R/CD-RW other than those recorded in the format s listed on page 4

• CD-ROM recorded in PHOTO CD format

• Data part of CD-Extra

•CDGraphicsdisc

• DVD Audio

• DATA DVD that does not contain MP3 files, JPEG image files, or DivX video files

• DVD-RAM

Also, the system cannot play the following discs:

• A DVD VIDEO with a different region code (page 6)

• A disc th at has a non-st andard shape (e.g., card, heart)

• A disc with paper or stickers on it

• A disc th at has the adhesive o f cellophane tape or a sticker still left on it

Note about CD-R/CD-RW/DVD-R/DVD-RW/DVD+R/DVD+RW

In some cases, CD-R/CD-RW/DVD-R/DVD-RW/DVD+R/DVD+RW cannot be played on this system due to the recording quality o r physical condition of the disc, or the charact er i stics of the recordi ng device and authoring software. The disc will not play if it has not been correctly finalized. For more information, refer to the operating instructions for the recording device. Note that some playback functions may not work with some DVD+RWs/DVD+Rs, even if they h ave been correctly finalized. In this case, view the disc by normal playback. Also some DATA CDs/DATA DVDs created in P acket Write format cannot be played.

Music discs encoded with copyright protection technologies

This product is designed to play bac k discs that co nform to the Compact Disc (C D ) s ta ndard. Recently, various music discs enc ode d with copyr i ght pr ot ection technologi es are marketed by some record compani es. Please be aw are that among t hose discs, the re are som e t hat do not confor m to the CD standard and may not b e playable by t hi s product.

Note on DualDiscs

A DualDisc is a two side d disc product w hi ch mates DVD recorded material on one side with digit al audio material on the other side. How ever, since the audio material side does not conf or m to the Compact Disc (CD) standard, p la yback on this pro duct is not guaranteed.

About Multi Session CD

• This system can play a Multi Session CD when an MP3 file is contained in the first session. Any subsequent MP3 files recorded in late r sessions can also be played back.

• This system can play a Multi Session CD 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 MP3 files and JPEG image files 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 ha s a region code printed on the rea r of the unit and will only play a D V D labeled w i th the same region code.

A DVD VID E O labeled will also play on this system. If y ou try to play any other DVD VIDEO, the message [Playback prohibited by area limitations.] will appear on the TV screen. Depending on the DVD VIDEO, no region code indication may be given even though playing the DVD VIDEO is prohibited by area restrictions.

Note about playback operations of a DVD or VIDEO CD

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 ﬂ exible 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 reﬂ ective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.

LASER DIODE AND FOCUS SEARCH

1. Open the case and turn POWER on with no disc inserted.

2. Conﬁ rm that the following operation is performed while observing the objecting lens from the clearance of DVD mechanism deck.

1) Conﬁ rm that laser beam is spread.

2) Up and down motion of the objective lens. (2 times)
