Operating Precautions; Radio - Toyota AUDIO 1-DIN Owner's Manual

OPERATING PRECAUTIONS

CAUTION
The driver should avoid operating the AUDIO system while driving.
Do not turn up the volume too much. Otherwise, warnings and sounds from
outside the vehicle cannot be heard, and could result in an accident.
Avoid using the AUDIO system when the vehicle compartment is extremely hot,
especially during the summer. Otherwise, the AUDIO system may be damaged.
Always use the system after cooling the vehicle compartment.
Do not disassemble or modify the AUDIO system as the interior structure of the
AUDIO unit is designed precisely. If you need any technical assistance, contact
your nearest dealer.
The AUDIO system works only when the ignition key (switch) is
"ON" or "ACC". However, do not leave the ignition switch "ON"
when the engine is not running. If you want to listen to the AUDIO
system when the engine is not running, place the ignition key (switch)
"ACC".

RADIO

Adjust the length of your antenna for best reception. Usually, a short
antenna length is best in large cities, and a fully extended antenna is best
for distant reception.
FM reception tips
When listening to the radio in a vehicle, some FM characteristics
may appear to be problems when they are not. This is because the
reception constantly changes if the vehicle is moving. Buildings, terrain,
signal distance, and noise from other vehicles all work against good
reception. The following characteristics are completely normal for a
given reception area, and they do not indicate any problem with the
radio itself.
Fading and Drifting: The FM range is limited to about 40km, except
for some high power stations.
If a vehicle is moving away from the station's transmitter, the signal
tends to fade and/or drift. This is a common condition with FM and is
accompanied by distortion.
Fading and drifting can be minimized to a certain degree by ne tuning
or tuning your radio to a stronger signal.
Static and Fluttering: When the line-of-sight link between a transmitter
and the vehicle is blocked by large buildings and so on, the radio
sound may be accompanied by static or fluttering due to the FM
characteristics. Similarly, a fluttering noise is sometimes heard when
driving along a tree-lined road.
This static and uttering can be reduced by adjusting the tone control
for turning off treble response until the disturbance has passed.
