Operation Manual

FM radio reception:
Range: FM range is normally limited to 25
to 30 miles (40 to 48 km), with monaural
(single channel) FM having slightly more
range than stereo FM. External influences
may sometimes interfere with FM station
reception even if the FM station is within
25 miles (40 km). The strength of the FM
signal is directly related to the distance
between the transmitter and receiver. FM
signals follow a line-of-sight path, exhib-
iting many of the same characteristics as
light. For example they will reflect off ob-
jects.
Fade and drift: As your vehicle moves
away from a station transmitter, the sig-
nals will tend to fade and/or drift.
Static and flutter: During signal interfer-
ence from buildings, large hills or due to
antenna position, usually in conjunction
with increased distance from the station
transmitter, static or flutter can be heard.
This can be reduced by lowering the
treble setting to reduce the treble re-
sponse.
Multipath reception: Because of the re-
flective characteristics of FM signals, di-
rect and reflected signals reach the re-
ceiver at the same time. The signals may
cancel each other, resulting in momentary
flutter or loss of sound.
AM radio reception:
AM signals, because of their low fre-
quency, can bend around objects and
skip along the ground. In addition, the
signals can be bounced off the iono-
sphere and bent back to earth. Because
of these characteristics. AM signals are
also subject to interference as they travel
from transmitter to receiver.
Fading: Occurs while the vehicle is
passing through freeway underpasses or
in areas with many tall buildings. It can
also occur for several seconds during
ionospheric turbulence even in areas
where no obstacles exist.
Static: Caused by thunderstorms, elec-
trical power lines, electric signs and even
traffic lights.
Satellite radio reception:
When the satellite radio (if so equipped)
is first installed or the battery has been
replaced, the satellite radio may not work
properly. This is not a malfunction. Wait
more than 10 minutes with satellite radio
ON for satellite radio to receive all of the
necessary data.
The satellite radio mode will be skipped
unless an optional satellite receiver and
antenna are installed and an XM
or
SIRIUS
TM
satellite radio service subscrip-
tion is active. Satellite radio is not avail-
able in Alaska, Hawaii and Guam.
Satellite radio performance may be af-
fected if cargo carried on the roof blocks
the satellite radio signal.
If possible, do not put cargo near the sat-
ellite antenna.
