By connecting an optional portable audio device 
to the AUX input jack (stereo mini jack) on the 
unit and then simply selecting the source, you 
can listen on your car speakers. The volume 
level is adjustable for any difference between the 
unit and the portable audio device. Follow the 
procedure below:

1  Turn off the portable audio device.
2  Turn down the volume on the unit.
3  Connect to the unit.

Be sure to adjust the volume for each connected 
audio device before playback.

1  Turn down the volume on the unit.
2 Press 

 repeatedly until “AUX” 

appears.
“FRONT IN” appears.

3  Start playback of the portable audio device at 

a moderate volume.

4  Set your usual listening volume on the unit.
5  Press the select button repeatedly until “AUX” 

appears, and rotate the volume control dial to 
adjust the input level (–8 dB to +18 dB).

•  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.

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.

Be careful not to splash juice or other soft drinks 
onto the unit or 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 

1

/

4

 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.

•  Some CD-Rs/CD-RWs (depending on the 

equipment used for its recording or the condition 
of the disc) may not play on this unit.

•  You cannot play a CD-R/a CD-RW that is not 

fi nalized.

This product is designed to play back 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.

A DualDisc is a two sided disc product which 
mates DVD recorded material on one side with 
digital audio material on the other side. However, 
since the audio material side does not conform to 
the Compact Disc (CD) standard, playback on this 
product is not guaranteed.

MP3, which stands for MPEG-1 Audio Layer-3, 
is a music fi le compression format standard. It 
compresses audio CD data to approximately 1/10 of 
its original size.
WMA, which stands for Windows Media Audio, is 
another music fi le compression format standard. It 
compresses audio CD data to approximately 1/22* 
of its original size.

* only for 64 kbps

•  The unit is compatible with the ISO 9660 level 

1 / level 2 format, Joliet/Romeo in the expansion 
format, and Multi Session.

•  The maximum number of:

–  folders (albums): 150 (including root and empty 

folders).

– MP3/WMA fi les (tracks) and folders contained 

in a disc: 300 (if a folder/fi le names contain 
many characters, this number may become less 
than 300).

–  displayable characters for a folder/fi le name is 

32 (Joliet), or 64 (Romeo).

•  ID3 tag versions 1.0, 1.1, 2.2, 2.3 and 2.4 apply 

to MP3 only. ID3 tag is 15/30 characters (1.0 and 
1.1), or 63/126 characters (2.2, 2.3 and 2.4).
WMA tag is 63 characters.

Notes
•  When naming an MP3 fi le/WMA fi le, be sure to add 

•  During playback of a VBR (variable bit rate) MP3/ 

•  When the disc is recorded in Multi Session, only the 

Notes on MP3

If you have any questions or problems concerning 
your unit that are not covered in this manual, 
consult your nearest Sony dealer.

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 fi re or explosion.

there may be an internal 
malfunction. In such a case, 
consult your nearest Sony 
dealer.
