Audio And Visual System (For Radio Receiver Type) System Description

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.

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.
   

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:
   

   
   
   
   

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. DualDiscs that mate DVD recorded material on one side with CD digital audio material on the other cannot be played.
   
5. Keep the discs away from dirt. Be careful not to damage the discs or leave fingerprints on them.
   
6. Hold discs by the outer edge and center hole with the label side up.
   
7. 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.
   
8. 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.
   
9. Keep the discs away from direct sunlight. (Exposure to direct sunlight may cause deformation of the disc, making the disc unusable.)
   
10. Do not use odd-shaped CDs because these may cause player malfunctions.
    
11. Do not use discs whose recording portion is transparent or translucent because they may not be inserted, ejected or played normally.
    
12. Use only 4.7 in. (12 cm) CDs.
    
13. Do not use 3 in. (8 cm) CDs either with or without adaptors.
    

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 may skip or stop in the middle of play. Ventilate or dehumidify the cabin for a while before using the player.
   
2. The CD may skip if the player experiences strong vibrations when the vehicle is driven on rough roads or similar uneven surfaces.
   

Cleaning

NOTICE:

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

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.

Radio reception problems

HINT:

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. 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.
   

   Text in Illustration

   *a	Phasing
   *b	Ionosphere





2. 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.

   Multipath





3. 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 less likely to deflect.

Noise problem
Technicians must have a clear understanding about each customer's noise complaint. Use the following table to diagnose noise problems.

The stereo jack adapter on radio receiver assembly is equipped with a USB terminal. Connecting a USB device or "iPod" to the No. 1 stereo jack adapter assembly allows music files to be played. Not only is it possible to play music from a USB device with audio functions, it is also possible to play MP3 or WMA music files that are stored on a USB device. In addition, "iPod" control software is installed, allowing file selection from playlists and operation using shuffle mode.

HINT:

Operation through the controls of a USB device or "iPod" cannot be performed while it is connected.

   HINT:

   Depending on differences between models or software versions etc., some models might be incompatible with this system.

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.
