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. Do not disassemble any part of the CD player.
    2. Do not apply oil to the CD player.
    3. Do not insert anything but a CD into the CD player.



  2. Usable discs



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


      E119759

  3. Precautions for use of discs

    NOTICE:
    1. Copy-protected CDs cannot be played.
    2. 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.
    3. Unfinalized CD-Rs and CD-RWs cannot be played.
    4. Keep the discs away from dirt. Be careful not to damage the discs or leave your fingerprints on them.
    5. Hold discs by the outer edge and center hole with the label side up.
    6. 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.
    7. If discs have adhesive tape, stickers, CD-R labels or any traces of such labels attached, the discs may not be ejected or player malfunctions may result.
    8. Keep the discs away from direct sunlight (Exposure to direct sunlight may cause deformation of the disc, making the disc unusable.).
    9. Do not use odd-shaped CDs because these may cause player malfunctions.
    10. Do not use discs whose recording portion is transparent or translucent because they may not be inserted, ejected or played normally.
    11. Use only 4.7 in. (12 cm) CDs.
    12. Do not use 3 in. (8 cm) CDs, either with or without adapters.

    HINT:
    1. When it is cold or it is raining, if the windows mist up, mist and condensation may form in the player. In such cases, the CD sound may skip or stop in the middle of play. Ventilate or dehumidify the cabin for a while before using the player.
    2. The CD sound may skip if the player experiences strong vibrations when the vehicle is driven on rough road or similar uneven surfaces.



  4. Cleaning

    NOTICE:
    Do not use a lens cleaner because it may cause a malfunction in the pickup portion of the player.




      I100151

    1. 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 inside to the outside in a radial direction.

      NOTICE:
      1. Pressing on the disc by hand or rubbing the disc with a hard cloth may scratch the disc surface.
      2. Use of solvents such as record spray, antistatic agents, alcohol, benzine, thinners, or a chemical cloth may cause damage to the disc, making the disc unusable.

AVC-LAN DESCRIPTION


  1. What is AVC-LAN?


    E145821E17

    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.

  2. 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:
      1. If a short to +B or short to ground is detected in the AVC-LAN circuit, communication is interrupted and the audio system will stop functioning.
      2. If the audio system has a navigation system installed, the multi-display unit acts as the master unit. If a navigation system is not installed, the audio head unit acts as the master unit instead. If the navigation receiver assembly is installed, it is the master unit.
      3. The radio receiver assembly contains a resistor that is necessary to enable communication on the different AVC-LAN circuits.
      4. The car audio system with an AVC-LAN circuit has a diagnostic function.
      5. Each component has a specified number (3-digit) called a physical address. Each function has a number (2-digit) called a logical address.


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 assembly with a 60 to 80 Ω resistor. This is essential for communication.

  3. If a short circuit or open circuit occurs in the AVC-LAN circuit, communication is interrupted and the audio system will stop functioning.


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.

  1. "Bluetooth" is a trademark owned by Bluetooth SIG, Inc.

  2. "Bluetooth" is a wireless connection technology that uses the 2.4 GHz frequency band.

    HINT:
    The communication performance of "Bluetooth" may vary depending on obstructions or radio wave conditions between communication devices, electromagnetic radiation, communication device sensitivity or antenna capacity.

  3. Hands-free function

    1. The "Bluetooth" built-in radio receiver and a "Bluetooth" compatible cellular phone*1 can be connected using a "Bluetooth" wireless connection. This enables the use of the hands-free function on the cellular phone even if the phone is in a pocket or bag. For this reason, it is not necessary to use a connector or cable to connect the cellular phone.
      *1: Some versions of "Bluetooth" compatible cellular phones may not function.

  4. "Bluetooth" audio function

    1. The "Bluetooth" built-in radio receiver assembly and a "Bluetooth" compatible portable audio player*2 can be connected using a "Bluetooth" wireless connection. This enables files stored in the portable audio player to be heard from the vehicle speakers. In addition, operations such as play/stop can be performed directly from the radio receiver assembly.
      *2: Some versions of "Bluetooth" compatible audio players may not be able to operate the "Bluetooth" function, or music may play, but functions available using the radio receiver assembly may be limited.

    2. Compatible "Bluetooth" audio devices

      "Bluetooth" specifications
      		Ver. 1.1 or higher (Ver. 2.0+EDR or higher recommended)

ASL (Automatic Sound Levelizer) FUNCTION OUTLINE

  1. The Automatic Sound Levelizer (ASL) function automatically adjusts the audio system volume level in order to compensate for increased vehicle noise (vehicle noise tends to increase as vehicle speed increases). The ASL adjusts the volume level based upon vehicle speed signals that it receives from the combination meter assembly.
