The volume level is adjustable for any difference between the unit and the portable audio device. Follow the procedure below:
Additional Information Precautions
If your car has been parked in direct sunlight, allow the unit to cool off before operating it. Power aerial 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.

Connecting the portable audio device
1 Turn off the portable audio device. 2 Turn down the volume on the unit. 3 Connect to the unit.
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.
Connecting cord* (not supplied)
* Be sure to use a straight type plug.

Adjust the volume level

Be sure to adjust the volume for each connected audio device before playback. 1 Turn down the volume on the unit. 2 Press (SOURCE) repeatedly until AUX 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 volume level.
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 centre out. Do not use solvents such as benzine, thinner, commercially available cleaners, or antistatic spray intended for analogue discs.
Playback order of MP3/WMA files
MP3/WMA Folder (album) MP3/WMA file (track)
Notes on CD-R/CD-RW 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 finalized.
Music discs encoded with copyright protection technologies
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.

Note on DualDiscs

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.
Notes When naming an MP3/WMA file, be sure to add the file expansion.mp3 /.wma to the file name. During playback of a VBR (variable bit rate) MP3/ WMA 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/WMA. 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/WMA session is played. If the disc has no data in any of these formats, NO MUSIC is displayed. Notes on MP3 Be sure to finalize the disc before using on the unit. If you play a high-bit-rate MP3, such as 320 kbps, sound may be intermittent. Notes on WMA Files made with lossless compression are not playable. Files protected by copyright are not playable.

About MP3/WMA files

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

* only for 64 kbps

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.
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 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 64 (Romeo). ID3 tag versions 1.0, 1.1, 2.2, 2.3 and 2.4 apply to MP3 only. ID 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 on the lithium battery Keep the lithium battery out of the reach of children. Should the battery be swallowed, immediately consult a doctor.
