Precautions

If your car has been parked in direct sunlight, allow the unit to cool off before operating it. Power antenna will extend automatically while the unit is operating. While driving, do not use the CUSTOM FILE feature or any other functions which may divert your attention from the road. If you have any questions or problems concerning your unit that are not covered in this manual, please consult your nearest Sony dealer.

Notes on discs

To keep the disc clean, do not touch the surface. Handle the disc by its edge. Keep your discs in their cases or disc magazines when not in use. Do not subject the discs to heat/high temperature. Avoid leaving them in parked cars or on dashboards/rear trays.

Moisture condensation

On a rainy day or in a very damp area, moisture condensation may occur inside the lenses and display of the unit. Should this occur, the unit will not operate properly. In such a case, remove the disc and wait for about an hour until the moisture has evaporated. Do not attach labels, or use discs with sticky ink/residue. Such discs may stop spinning when used, causing a malfunction, or may ruin the disc.
To maintain high sound quality
Be careful not to splash juice or other soft drinks onto the unit or discs.
Do not use any discs with labels or stickers attached. The following malfunctions may result from using such discs: Inability to eject a disc (due to a label or sticker peeling off and jamming the eject mechanism). Inability to read audio data correctly (e.g., playback skipping, or no playback) due to heat shrinking of a sticker or label causing a disc to warp. 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. You cannot play 8 cm CDs.

Before playing, clean the discs with a commercially available cleaning cloth. Wipe each disc from the center out. Do not use solvents such as benzine, thinner, commercially available cleaners, or antistatic spray intended for analog discs.

About MP3 files

MP3 (MPEG 1 Audio Layer-3) is a standard technology and format for compressing a sound sequence. The file is compressed to about 1/10 of its original size. Sounds outside the range of human hearing are compressed while the sounds we can hear are not compressed.
You can play MP3 files recorded on CD-ROMs, CD-Rs, and CD-RWs. The disc must be in the ISO 9660*1 level 1 or level 2 format, or Joliet or Romeo in the expansion format. You can use a disc recorded in Multi Session*2. *1 ISO 9660 Format The most common international standard for the logical format of files and folders on a CD-ROM. There are several specification levels. In Level 1, file names must be in the 8.3 format (no more than 8 characters in the name, no more than 3 characters in the extension.MP3) and in capital letters. Folder names can be no longer than 8 characters. There can be no more than 8 nested folder levels. Level 2 specifications allow file names up to 31 characters long. Each folder can have up to 8 trees. For Joliet or Romeo in the expansion format, make sure of the contents of the writing software, etc. *2 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. CD-Extra: The format which records audio (audio CD data) as tracks on session 1, and records data as tracks on session 2. Mixed CD: In this format, data is recorded as track 1, and audio (audio CD data) is recorded as track 2.
