SYSTEM DESCRIPTION

Scheme 144

1. CD PLAYER OUTLINE A CD player uses a laser pickup to read digital signals recorded on CDs. By converting the digital signals to analog, music and other contents can be played. WARNING: Do not look directly at the laser pickup because the CD player uses an invisible laser beam. Be sure to operate the player only as instructed. NOTE: Do not disassemble any part of the CD player. Do not apply oil to the CD player. Do not insert anything but a CD into the CD player. Usable CDs Precautions for use of discs NOTE: Copy-protected CDs cannot be played. Dual discs cannot be played. Playing dual discs may cause malfunctions of the CD player. CD-Rs and CD-RWs may not be played depending on the recording conditions or characteristics of the discs, or due to damage, dirt, or deterioration caused by leaving the discs in the cabin for a long time. Unfinalized CD-Rs and CD-RWs cannot be played. PAL or SECAM color television standard discs cannot be played. (Only NTSC discs can be played.) Keep the discs away from dirt. Be careful not to damage the discs or leave your fingerprints on them. Hold discs by the outer edge and center hole with the label side up. Leaving the disc exposed halfway out of the slot for a long time after pressing the disc eject button may cause deformation of the disc, making the disc unusable. If discs have adhesive tape, stickers, CDR labels, or any traces of such labels attached, the discs may not be ejected or player malfunctions may result. Keep the discs away from direct sunlight. (Exposure to direct sunlight may cause deformation of the disc, making the disc unusable.) Do not use odd-shaped CDs because these may cause player malfunctions. Do not use discs whose recording portion is transparent or translucent because they may not be inserted, ejected, or played normally. HINT: When it is cold or it is raining, if the windows mist up, mist and also dew may form in the player. In such a case, the CD may skip or the CD may stop in the middle of play. Ventilate or dehumidify the cabin for a while before using the player. The CD may skip if the player experiences strong vibrations when the vehicle is driven on rough road or similar uneven surface(s). Cleaning NOTE: Do not use a lens cleaner because it may cause a malfunction in the pickup portion of the player. If dirt is on the disc surface, wipe it clean with a soft dry cloth such as an eyeglass cleaner for plastic lenses from the center to the outside in a radial direction. NOTE: Pressing on the disc by hand or rubbing the disc with a hard cloth may scratch the disc surface. Use of solvent such as a record spray, antistatic agent, alcohol, benzine, and thinner, or a chemical cloth may cause damage to the disc, making the disc unusable.
2. MP3/WMA OUTLINE Playable MP3 file standards Compatible standard MP3 (MPEG1 LAYER3, MPEG2 LSF LAYER 3) Compatible sampling frequency MPEG1 LAYER3: 32, 44.1, 48 (kHz) MPEG2 LSF LAYER3: 16, 22.05, 24 (kHz) Compatible bit rate MPEG1 LAYER3: 64, 80, 96, 112, 128, 160, 192, 224, 256, 320 (kbps) MPEG2 LSF LAYER3: 64, 80, 96, 112, 128, 160 (kbps) Compatible with VBR Compatible channel mode Stereo, joint stereo, dual channel, monaural Playable WMA file standards Compatible standard WMA Ver. 7, 8, and 9 Compatible sampling frequency 32, 44.1, 48 (kHz) Compatible bit rate Ver. 7, 8: CBR48, 64, 80, 96, 128, 160, 192 (kbps) Ver. 9: CBR48, 64, 80, 96, 128, 160, 192, 256, 320 (kbps) Compatible with playback of channel 2 only ID3 tags and WMA tags Additional textual information called ID3 tags can be input to MP3 files. Information such as song titles and artist names can be stored. HINT: This player is compatible with the ID3 tags of ID3 Ver. 1.0 and 1.1, and ID3 Ver. 2.2 and 2.3. (Number of characters complies with ID3 Ver. 1.0 and 1.1.) Additional textual information called WMA tags can be input to WMA files. Information such as song titles and artist names can be stored. Usable media Only CD-ROMs, CD-Rs (CD-Recordable), and CD-RWs (CD-ReWritable) can be used to play MP3/WMA files. NOTE: CD-Rs and CD-RWs are more easily affected by a hot and humid environment than discs used for normal audio CDs. For this reason, some CD-Rs and CD-RWs may not be played. If there are fingerprints or scratches on the disc, the disc may not be played or the CD may skip. Some CD-Rs and CD-RWs deteriorate if they are left in the cabin for a long time. Keep CD-Rs and CD-RWs in a storage case that is impenetrable to light. Usable media format Usable media format Disc format CD-ROM Mode 1, CD-ROM XA Mode 2 Form1 File format ISO9660 Level 1 and Level 2 (Joliet and Romeo) HINT: As for MP3/WMA files written in any format other than those above, the contents of the files may not be played normally or the file names or folder names may not be displayed correctly. This player is compatible with multi-session discs and can play CD-Rs and CD-RWs on which MP3/WMA files are added. However, only the first session can be played. Discs whose first session includes both music data and MP3 or WMA format data cannot be played. Standard and restrictions Maximum directory levels 8 levels Maximum number of characters for a folder name/file name 32 characters Maximum number of folders 192 (Including empty folders, route folders, and folders that do not contain MP3/WMA files) Maximum number of files in a disc 255 (Including non-MP3/WMA files) File names Only files with an extension of ".mp3" or ".wma" can be recognized and played as MP3 or WMA files. Save MP3 or WMA files with an extension of ".mp3" or ".wma". NOTE: If saving non-MP3 or non-WMA files with an extension of ".mp3" or ".wma", those files are wrongly recognized as MP3 or WMA files and played. A loud noise may occur and damage to the speakers may result.

DESCRIPTION

Sound signals that have been amplified by the stereo component amplifier are sent to the speakers from the radio receiver through this circuit. If there is a short in this circuit, the sound cannot be heard from the speakers even though there is no malfunction in the speakers.

The stereo jack adapter sends an external device sound signal to the radio receiver through this circuit. The sound signal that has been sent is amplified by the stereo component amplifier, and then is sent to the speakers. If there is an open or short in the circuit, sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier, radio receiver, or speakers.
