Notes on CD-Rs (recordable CDs)/CDRWs (rewritable CDs)
This unit can play the following discs:
Type of discs Label on the disc

Audio CD

MP3 files
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.
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/CD-RW that is not finalized*. You can play MP3 files recorded on CDROMs, CD-Rs, and CD-RWs. A CD-R/CD-RW to which a session can be added can be played.
* A process necessary for a recorded CD-R/CD-RW disc to be played on the audio CD player.
Do not use any discs with labels or stickers attached as this may cause 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. Before playing, clean 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.

The playback order of the MP3 files
The playback order of the folders and files is as follows:

Folder (album)

Resetting the unit

MP3 file (track)

Before operating the unit for the first time, or after replacing the car battery or changing the connections, you must reset the unit. Remove the front panel and press the RESET button with a pointed object, such as a ball-point pen.
RESET button Note Pressing the RESET button will erase the clock setting and some stored contents.
Tree 1 (root) Tree 2 Tree 3 Tree 4 Tree 5
Notes A folder that does not include an MP3 file is skipped. Maximum folder number: 255 (including root folder and empty folders) The maximum number of MP3 files and folders that can be contained in a disc: 512 When a file/folder name contains many characters, this number may become less than 512. The maximum number of trees which can be played is 8. Tip To specify a desired playback order, before the folder or file name, input the order by number (e.g., 01, 02), then record contents onto a disc. (The order differs depending on the writing software.)

Replacing the lithium battery
Under normal conditions, batteries 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.

Fuse (10 A)

Never use a fuse with an amperage rating exceeding the one supplied with the unit as this could damage the unit.

Cleaning the connectors

The unit may not function properly if the connectors between the unit and the front panel are not clean. In order to prevent this, detach the front panel (page 10) and clean the connectors with a cotton swab dipped in alcohol. Do not apply too much force. Otherwise, the connectors may be damaged.

Notes on lithium battery

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.
