Notes on chip component replacement
•Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam­aged by heat.
Flexible Circuit Board Repairing
•Keep the temperature of the 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.
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous ra­diation exposure.
This appliance is classified as a CLASS 1 LASER product. This label is located on the rear exterior.
The following caution label is located inside the apparatus.
Design and specifications are subject to change without notice.
SAFETY-RELATED COMPONENT 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.
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 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.

Region code of DVDs you can play on this system
Your system has a region code printed on the back of the unit and will only play DVDs labeled with identical region code.
DVDs labeled will also be played on this

•CD-Rs/CD-RWs other than those recorded in the following formats: –music CD format –video CD format –MP3/JPEG format that conforms to
ISO9660* Session*

•Data part of CD-Extras
•Super Audio CDs
•Progressive JPEG format files cannot be played on this system.
• DVD-RWs in VR mode (DVD-RWs created in VR (Video Recording) mode allow the contents to be programed or edited.)
• DVD-ROMs
• DVD Audio discs
•A DVD with a different region code.
•Audio tracks in MP3PRO format.
•A disc that has a non-standard shape (e.g., card, heart).
•A disc with paper or stickers on it.
•A disc that has the adhesive, cellophane tape, or a sticker still left on it.
*1
ISO9660 Format The most common international standard for the logical format of files and folders on a CD-ROM. There are severa l specification levels. In Leve l 1, file names must be in the 8.3 format (no more than eight characters in the name, no more than three characters in the extension “.MP3” or “.JPG”) and in capital letters. Folder names can be no longer than eight characters. There can be no more than eight nested folder levels. Level 2 sp ecifications allow file names and folder names up to 31 characters long. Each folder can have up to 8 trees. For Joliet in the expansion format (file and folder names can have up to 64 characters) m ake sure of the contents of the writing software, etc.
*2
Multi Session This is a recording method that enables adding of data using the Trac k-At-Once method. Conventional CDs begin at a CD control area called the Lead-in and end at an area called Lead-out. A Multi Session CD is a CD having multiple sessions, with each segment from Lead-in to Lead-out regarded as a single session. CD-Extra: This format records audio (audio CD data) on the tracks in se ssion 1 and data on the tracks in session 2.

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.
Copyrights
This product incorporates copyright protection technology that is protected by U.S. patents and other intellectual property rights. Use of this copyright protection technology must be authorized by Macrovision, and is intended for home and other limited viewing uses only unless otherwise authorized by Macrovision. Reverse engineering or disassembly is prohibited.
Music discs encoded with copyright prot ec ti on technologies
This product is designed to playback 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.
Cautions when playing a disc that is recorded in Multi Session
•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.
Notes on discs
•This system can play CD-R/CD-RW discs edited by the user. However, note that playback of some discs may not be possible depending on the recording device used for recording or the disc condition.
•Discs recorded on CD-R/CD-RW drives may not be played back because of scratches, dirt, recording condition or the driver’s characteristics.
•CD-R and CD-RW discs that have not been correctly finalized (processing to allow play by a normal CD player) cannot be played.
•CD-R and CD-RW discs recorded in multi­session that have not ended by “closing the session” are not supported.
•The system may be unable to play MP3/JPEG format files that do not have the extender “.MP3,” “.JPG,” or “.JPEG.”
•Attempting to play non-MP3/JPEG format files that have the extender “.MP3,” “.JPG,” or “.JPEG” may result in noise or malfunction. Playback is possible up to 8 levels.
•With formats other than ISO9660 level 1 and 2, folder names or file names may not be displayed correctly.
•The following discs take a longer time to start playback:
–a disc recorded with a complicated tree
structure.
–a disc recorded in Multi Session.
–a disc to which data can be added (non-
finalized disc).
•Some CD-Rs, CD-RWs, DVD-Rs or DVD­RWs (in video mode) (DVD-RWs created in video mode have the same format as a DVD VIDEO) cannot be played on this system depending upon the recording quality or physical condition of the disc, or the characteristics of the recording device. Furthermore, the disc will not play if it has not been correctly finalized. For more information, see the operating instructions for the recording device.
•A disc recorded in packet write format cannot be played.

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 objectiv e lens.
RELEASING THE DISC LOCK
The disc lock function for the antitheft of an demonstration disc in the store is equipped.
Releasing Procedure :
While pressing the [ENTER] key , press the Z key for 5 seconds. The message “UNLOCKED” is displayed and the disc is unlocked.
Note: When “LOCKED” is displayed, the disc lock is not released by
turning power on/off with the I/1 key.
