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.
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.
To maintain high sound quality
Be careful not to splash juice or other soft drinks onto the unit or discs.
Notes on discs
- To keep a disc clean, do not touch its surface. Handle the disc by its edge.
- Keep your discs in their cases or disc magazines when not in use.
- Do not subject discs to heat/high temperature. Avoid leaving them in a parked car or on a dashboard/rear tray.
- 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.






- 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 (3 in) 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.

- The unit is compatible with the ISO 9660 level 1/level 2 format, Joliet/Romeo in the expansion format, ID3 tag version 1.0, 1.1, 2.2, 2.3 and 2.4, and Multi Session.
• The maximum number of:
– folders (groups): 150 (including root and empty folders).
- MP3 files (tracks) and folders contained in a disc: 300 (if a folder/file names contain many characters, this number may become less than 300).
–displayable characters for a folder/file name is 32 (Joliet), or 32/64 (Romeo); ID3 tag is 15/30 characters (1.0, 1.1, 2.2 and 2.3), or 63/126 characters (2.4).

Notes
- Be sure to finalize the disc before using on the unit.
- When naming an MP3 file, be sure to add the file expansion “.mp3” to the file name.
- If you play a high-bit-rate MP3, such as 320 kbps, sound may be intermittent.
- During playback of a VBR (variable bit rate) MP3 file or fast-forward/reverse, elapsed playing time may not display accurately.
- When the disc is recorded in Multi Session, only the first track of the first session format is recognized and played (any other format is skipped). The priority of the format is CD-DA, ATRAC CD and MP3.
- When the first track is a CD-DA, only CD-DA of the first session is played.
- When the first track is not a CD-DA, an ATRAC CD or MP3 session is played. If the disc has no data in any of these formats, "NO MUSIC" is displayed.
About ATRAC CD
ATRAC3plus format
ATRAC3, which stands for Adaptive Transform Acoustic Coding3, is audio compression technology. It compresses audio CD data to approximately 1/10 of its original size. ATRAC3plus, which is an extended format of ATRAC3, compresses the audio CD data to approximately 1/20 of its original size. The unit accepts both ATRAC3 and ATRAC3plus format.
ATRAC CD
ATRAC CD is recorded audio CD data which is compressed to ATRAC3 or ATRAC3plus format using authorized software, such as SonicStage 2.0 or later, or SonicStage Simple Burner.
• The maximum number of:

Maintenance
Replacing the lithium battery of the card remote commander
Under normal conditions, the battery will last approximately 1 year. (The service life may be shorter, depending on the conditions of use.)
When the battery becomes weak, the range of the card remote commander becomes shorter.
Replace the battery with a new CR2025 lithium battery. Use of any other battery may present a risk of fire or explosion.

- Keep the lithium battery out of the reach of children. Should the battery be swallowed, immediately consult a doctor.
- Wipe the battery with a dry cloth to assure a good contact.
- Be sure to observe the correct polarity when installing the battery.
- Do not hold the battery with metallic tweezers, otherwise a short-circuit may occur.
WARNING
Battery may explode if mistreated. Do not recharge, disassemble, or dispose of in fire.
Fuse replacement
When replacing the fuse, be sure to use one matching the amperage rating stated on the original fuse. If the fuse blows, check the power connection and replace the fuse. If the fuse blows again after replacement, there may be an internal malfunction. In such a case, consult your nearest Sony dealer.
