You can listen to the car audio system
when the ignition key is at “ON” or
“ACC”. However, if the engine is not
running, the key must be in the “ACC”
position.
ILLUMINATION CONTROL LOGIC
When the instrument panel lights are on,
the letters on operable buttons of the
mode in current use light up. On some au-
dio-units, the mode selection and eject
buttons also light up.
On some audio-units, when a cassette
tape is not in the slot, the letters on the
tape mode buttons do not light up, but the
slot lights up for easy access. Once a cas-
sette tape is inserted, the letters on the
tape mode buttons light up, and the slot
stops illuminating.
RADIO
FM reception tips
Most of us are not aware that a vehicle is
not an ideal place to listen to a radio. Be-
cause it moves, reception conditions
change continuously. Buildings, terrain,
signal distance and noise from other ve-
hicles are all working against good recep-
tion. Some FM reception conditions may
appear to be problems even though they
are normal.
The following characteristics are normal
for a given reception area, and they do not
indicate any problem with the radio itself.
Fading and Drifting: On the average,
the broadcast range of FM stations is
limited to about 40 km (25 miles), ex-
cept for some high power stations.
If a vehicle is moving away from the
desired station’s transmitter, the signal
will tend to fade and/or drift. This phe-
nomenon is more noticeable with FM
than with AM, and is accompanied by
distortion.
Fading and drifting can be minimized
to a certain degree by fine tuning, or
you should tune in to a stronger signal.
Static and Fluttering: When the line-
of-sight path between a transmitter
and vehicle is blocked by large build-
ings or the like, static or fluttering may
occur because of the characteristic of
FM. In a similar effect, a fluttering
noise is sometimes heard when driv-
ing along a tree-lined road.
This static and fluttering can be re-
duced by adjusting the tone control for
greater bass response until the distur-
bance has passed.
