• Discs with non-standard shapes (e.g., heart,

square, star) cannot be played on this unit. Attempting to do so may damage the unit. Do not use such discs.

• A disc with paper or stickers on it.

• A disc that has the adhesive, cellophane tape,

or a sticker still left on it.

A logical format of files and folders on a CDROMs, defined by ISO (International Organization for Standardization).

Multi Session This is a recording method that enables adding of data using the Track-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.

Notes on CD-R and CD-RW

• Some CD-Rs or CD-RWs 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.

• Discs recorded on CD-R/CD-RW drives may

not be played back because of scratches, dirt, recording condition or the driver’s

• CD-R and CD-RW discs recorded in packet

write format are not supported.

• CD-R and CD-RW discs that have not ended

by “closing the session” are not supported.

• The system may be unable to play MP3

format files that do not have the “.MP3” extension.

• Attempting to play non-MP3 format files that

have the “.MP3” extension may result in noise or malfunction.

• With formats other than ISO9660 Level 1,

Joliet and Romeo, folder names or file names may not be displayed correctly.

• The following discs take a longer time to start

playback. –a disc recorded with complicated tree

structure. –a disc recorded in Multi Session. –a disc to which data can be added (non-

finalized disc).

Music discs encoded with copyright protection 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

If the disc begins with a CD-DA session, it is

•

recognized as a CD-DA (audio) disc, and playback continues until an MP3 session is encountered.

If the disc begins with an MP3 session, it is

•

recognized as an MP3 disc, and playback continues until a CD-DA (audio) session is encountered. The playback range of an MP3 disc is

•

determined by the tree structure of files produced by analyzing of the disc.

A disc with a mixed CD or CD-Extra format

•

will be recognized as a CD-DA (audio) disc.

SERVICING NOTES

CX-J3000/J3000M

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 pickup 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 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.
