AUDIO AND VISUAL SYSTEM(for Radio and Display Type) SYSTEM DESCRIPTION


  1. CD (Compact Disc) PLAYER OUTLINE


    1. A compact disc player uses a laser pickup to read digital signals recorded on a compact disc (CD). By converting the digital signals to analog, it can play music and audio.

      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.

      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.

    2. Usable discs


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

        A005KKL

    3. Precautions for use of discs

      Note


      • Copy-protected CDs cannot be played.

      • 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.

      • 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, CD 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.

      Tech Tips


      • 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.

      • The CD sound may skip if the player experiences strong vibrations when the vehicle is driven on rough roads or similar uneven surface(s).

    4. Cleaning

      Note

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


      1. A005HX3

        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.

        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.

  7. RADIO DESCRIPTION


    1. Radio frequency band


      1. Radio broadcasts use the radio frequency bands shown in the table below.

        A005IQ8E02
    2. A005IDIE02
      Text in Illustration
      *a FM (Stereo)
      *b FM (Monaural)
      *c AM

      Service area


      1. The service areas of AM and FM broadcasts are vastly different. Sometimes an AM broadcast can be received very clearly but an FM stereo broadcast cannot. An FM stereo broadcast has the smallest service area, and is prone to pick up static and other types of interference such as noise.

    3. Radio reception problems

      Tech Tips

      In addition to static, other problems such as "phasing", "multipath", and "fade out" exist. These problems are not caused by electrical noise, but by the radio signal propagation method itself.


      1. A005IK6E02
        Text in Illustration
        *a Phasing
        *b Ionosphere

        Phasing

        AM broadcasts are susceptible to electrical interference and another kind of interference called phasing. Occurring only at night, phasing is the interference created when a vehicle receives 2 radio wave signals from the same transmitter. One signal is reflected off the ionosphere and the other signal is received directly from the transmitter.

      2. A005H2DE02
        Text in Illustration
        *a Multipath

        Multipath

        Multipath is a type of interference created when a vehicle receives 2 radio wave signals from the same transmitter. One signal is reflected off buildings or mountains and the other signal is received directly from the transmitter.

      3. A005HZYE02
        Text in Illustration
        *a Fade Out

        Fade out

        Fade out is caused by objects (buildings, mountains, and other such large obstacles) that deflect away part of a signal, resulting in a weaker signal when the object is between the transmitter and vehicle. High frequency radio waves, such as FM broadcasts, are easily deflected by obstructions. Low frequency radio waves, such as AM broadcasts, are much more difficult to deflect.

    4. Noise problem

      Technicians must have a clear understanding about the noise complaint of each customer. Use the following table to diagnose noise problems.

      Radio Frequency Noise Occurrence Condition Presumable Cause
      AM Noise occurs in a specified area Foreign noise
      AM Noise occurs when listening to an intermittent broadcast An identical program transmitted from multiple towers can cause noise where the signals overlap
      AM Noise occurs only at night Music beat from a distant broadcast
      FM Noise occurs while driving in a specified area Multipath or phasing noise resulting from a change in FM frequency

      Tech Tips

      If the noise does not match the examples above, refer to the descriptions about phasing and multipath.

  8. AUTOMATIC SOUND LEVELIZER (ASL) FUNCTION OUTLINE


    1. The ASL function automatically adjusts the sound data in order to enable to hear the clear sound from the audio system even when vehicle noise increases (as vehicle noise increases, the volume is turned up etc.). Vehicle speed signals are received from the combination meter assembly and used for the ASL.
