(b) Matters that require attention when checking:

Noise coming into the radio usually has no harm for
daily use as the noise protection is taken, and it is
very rate for an extremely loud noise to come in.
When extremely loud noise comes into the radio,
check if the grounding is normal where the antenna
is installed.

Check if all the regular noise prevention parts are
properly installed, and if there is any installation of
non-authorized parts and non-authorized wiring.

If you leave the radio under out of tune (not turning),
it is easy to diagnose the phenomenon as noise oc-
curs frequently.
(c) Antenna and noise:
Electronic signal received by the antenna will reach to the
radio transmitting through the core wire of the coaxial
cable. Any noise wave other than radio wave is mixed into
this core wire, that naturally causes noise in the radio and
poor sound quality. In order to prevent the noise from
coming into radio, the core wire inside the coaxial cable
is covered with a mesh wire called shield wire which trans-
mits the noise to the ground.
5. COMPACT DISC PLAYER
Compact Disc Players use a laser beam pick-up to read the dig-
ital signals recorded on the CD and reproduce analog signals
of the music, etc.
HINT:
Never attempt to disassemble or oil any part of the player unit.
Do not insert any object other than a disc into the magazine.
NOTICE:
CD players use an invisible laser beam which could cause
hazardous radiation exposure. Be sure to operate the play-
er correctly as instructed.
6. Tape player/head cleaning:
MAINTENANCE
(a) Raise the cassette door with your finger.
Next, using a pencil or similar object, push in the guide.
(b) Using a cleaning pen or cotton applicator soaked in clean-
er, clean the head surface, pinch rollers and capstans.

7. CD player/disc cleaning:
MAINTENANCE
If the disc gets dirty, clean the disc by wiping the surface from
the center to outside in the radial directions with a soft cloth.
NOTICE:
Do not use a conventional record cleaner or anti-static pre-
servative.
8. OUTLINE OF AVC-LAN
(a) What is AVC-LAN?
AVC-LAN is the abbreviation, which stands for Audio Visual Communication-Local Area Network.
This is a unified standard co-developed by 6 audio manufactures associated with Toyota Motor Corpo-
ration.
The Unified standard covers signals, such as audio signal, visual signal, signal for switch indication
and communication signal. Radio receiver assembly and RSA (Rear Seat Audio) panel have a resis-
tance (60 - 80 W) required for communication.
(b) Objectives
Recently the car audio system has been rapidly developed and functions have been changed drasti-
cally. The conventional system has been switched to the multi-media type such as a navigation sys-
tem. At the same time the level of customers needs to audio system has been upgraded. This lies be-
hind this standardization.
The concrete objectives are explained below.
(1) When products by different manufactures were combined together, there used to be a case that
malfunction occurred such as sound did not come out. This problem has been resolved by stan-
dardization of signals.
(2) Various types of after market products have been able to add or replace freely.
(3) Because of the above (2), each manufacture has become able to concentrate on developing
products in their strongest field. This has enabled many types of products provided inexpensive-
ly.
(4) In general, a new product developed by one particular manufacture could not be used due to
a lack of compatibility with other manufactures products. Because of this new standard, users
can enjoy many compatible products from different manufacture anytime they went.
(c) The above descriptions are the objectives to introduce AVC-LAN. By this standardization, develop-
ment of new products will no longer cause systematic errors.

NOTICE:
When replacing the internal mechanism (computer part) of the audio system, be careful that no part
of your body or clothing comes in contact with the terminals of the leads from the IC, etc. of the re-
placement part (spare part).
HINT:
This inspection procedure is a simple troubleshooting which should be carried out on the vehicle during sys-
tem operation and was prepared on the assumption of system component troubles (except for the wires and
connectors, etc.).
Always inspect the trouble taking the following items into consideration.
Open or short circuit of the wire harness
Connector or terminal connection fault
