1. DISC PLAYER OUTLINE

  1.  A CD player uses a laser pickup to read digital signals recorded on CDs. By converting the digital signals to analog, music and other content can be played.

CAUTION: 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.

NOTICE:

  1.  Usable discs
  1.  The CD player can only play audio CDs, CD-Rs (CD-Recordable), and CD-RWs (CDReWritable) that have any of the following marks:

MP3/WMA OUTLINE

  1. File names
  1.  Only files with an extension of ".mp3" or ".wma" can be recognized and played as MP3 or WMA files.
  2.  Save MP3 or WMA files with an extension of ".mp3" or ".wma".

NOTICE: 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 speaker may result.

3. AVC-LAN DESCRIPTION

  1.  What is AVC-LAN?

AVC-LAN DESCRIPTION

AVC-LAN, an abbreviation for "Audio Visual Communication Local Area Network", is a united standard developed by the manufacturers in affiliation with Toyota Motor Corporation. This standard pertains to audio and visual signals as well as switch and communication signals.

  1.  Purpose:

Recently, car audio systems have rapidly developed and the functions have vastly changed. The conventional car audio system is being integrated with multi-media interfaces similar to those in navigation systems. At the same time, customers are demanding higher quality from their audio systems. This is merely an overview of the standardization background. The specific purposes are as follows:

  1.  To solve sound problems, etc. caused by using components of different manufacturers through signal standardization.
  2.  To allow each manufacturer to concentrate on developing products they do best. From this, reasonably priced products can be produced.

HINT:

4. COMMUNICATION SYSTEM OUTLINE

  1.  Components of the audio system communicate with each other via the AVC-LAN.
  2.  The master component of the AVC-LAN is a radio receiver with a 60 to 80 Ω resistor. This is essential for communication.
  3.  If a short circuit or open circuit occurs in the AVCLAN circuit, communication is interrupted and the audio system will stop functioning.

5. DIAGNOSTIC FUNCTION OUTLINE

  1.  The audio system has a diagnostic function (the result is indicated on the master unit).
  2.  A 3-digit hexadecimal component code (physical address) is allocated to each component on the AVC-LAN. Using this code, the component in the diagnostic function can be displayed.
