HINT:



When it is cold or raining, if mist forms on the windows, mist and dew may form in the
player. In such a case, the CD may skip or the CD may stop playing. 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 road or similar uneven surfaces.

d. Cleaning

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.

2. MP3/WMA OUTLINE

a. Playable MP3 file standards

PLAYABLE MP3 FILE STANDARDS



Do not use discs whose recording portion is transparent or
translucent because they may not be inserted, ejected, or
played normally.

NOTE:

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

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.

NOTE:



CD-Rs and CD-RWs are more easily affected by a hot and
humid environment than discs used for normal audio CDs.
For this reason, some CD-Rs and CD-RWs may not be
playable.



If there are fingerprints or scratches on the disc, the disc
may not be playable or the CD may skip.



Some CD-Rs and CD-RWs deteriorate if they are left in the
cabin for a long time.



Keep CD-Rs and CD-RWs in a storage case that is
impenetrable to light.

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.

b. 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:



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.



If the audio system has a navigation system installed, the multi-display unit acts as the
master unit. If the navigation system is not installed, the audio head unit acts as the
master unit instead. If the radio and navigation assembly is installed, it is the master
unit.

4. COMMUNICATION SYSTEM OUTLINE

a. Components of the audio system communicate with each other via the AVC-LAN.

b. The master component of the AVC-LAN is a radio receiver with a 60 to 80 ohms resistor. This is

essential for communication.

c. If a short circuit or open circuit occurs in the AVC-LAN circuit, communication is interrupted and

the audio system will stop functioning.
