System Description

TOUCH SWITCH OUTLINE
Touch switches are touch-sensitive (interactive) switches operated by touching the screen. When a switch is pressed, the outer film bends in to contact the inner glass at the pressed position. By doing this, the voltage ratio is measured and the pressed position is detected.

DVD (Digital Versatile Disc) PLAYER OUTLINE (for Navigation Map)
1. The navigation receiver assembly uses a laser pickup to read the digital signals recorded on a DVD.
  WARNING:
  Do not look directly at the laser pickup because the navigation receiver assembly uses an invisible laser beam.
  
  Be sure to operate the navigation system only as instructed.
  NOTE:
  - Do not disassemble any part of the navigation receiver assembly.
  - Do not apply oil to the navigation receiver assembly.
  - Do not insert anything but a DVD into the navigation receiver assembly.
DVD (Digital Versatile Disc) PLAYER OUTLINE (for DVD Player)
1. The DVD player can only play DVD videos and video CDs that have any of the following marks:

  1. Precaution for use of discs
    NOTE:
    Keep the discs away from dirt. Be careful not to damage the discs or leave 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.
    
    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.
    
    DualDiscs that mate DVD recorded material on one side with CD digital audio material on the other cannot be played.
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.
  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.
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:

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.
  - DualDiscs that mate DVD recorded material on one side with CD digital audio material on the other 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 they 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 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.
  - The CD may skip if the player experiences strong vibrations when the vehicle is driven on rough roads or similar uneven surfaces.
4. Cleaning

  NOTE:
  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.
    NOTE:
    Pressing on the disc by hand or rubbing the disc with a hard cloth may scratch the disc surface.
    
    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.

*c	Cellular Tower	-	-

"Bluetooth" is a trademark owned by Bluetooth SIG. Inc.
"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.
Hands-free function
1. The "Bluetooth" built-in navigation receiver assembly 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.

RADIO DESCRIPTION

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

Service area

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. FM stereo has the smallest service area, and is prone to pick up static and other types of interference such as noise.

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.

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

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.

TEXT IN ILLUSTRATION

Multipath

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.

Fade Out

Noise problem

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

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

AUTOMATIC SOUND LEVELIZER (ASL) 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.
DIAGNOSTIC FUNCTION OUTLINE
1. The navigation system has a diagnostic function (the result is indicated on the master unit).
