Static and flutter: Duringsignal interference 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 adjusting the
treble control to reduce treble response.
Multipath reception: Because of the reflective
characteristicsofFM signals,directand reflected
signals reach the receiver at the same time. The
signals may cancel each other, resulting in mo-
mentary flutter or loss of sound.
AM RADIO RECEPTION
AM signals, because of their low frequency, can
bend around objects and skip along the ground.
In addition, the signals can be bounced off the
ionosphere and bent back to earth. Because of
these characteristics, AM signals are also sub-
ject tointerference as they travelfrom 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, electrical
power lines, electric signs and even traffic lights.
SATELLITE RADIO RECEPTION (if so
equipped)
When the satellite radio is used for the first time
or the battery has been replaced, the satellite
radio may not work properly. This is not a mal-
function.Waitmore than10 minuteswith satellite
radio ON and the vehicle outside of any metal or
large building for satellite radio to receive all of
the necessary data.
No satellite radio reception is available and “NO
SAT” is displayed when the SAT band option is
selected unless optional satellite receiver and
antenna are installed and an XMா satellite radio
service subscription is active. Satellite radio can
only be installed in vehicles that were factory
pre-wired for satellite radio. Satellite radio is not
available in Alaska, Hawaii and Guam.
Satellite radio performance may be affected if
cargocarriedon theroofblocks thesatelliteradio
signal.
If possible, do not put cargo over the satellite
antenna.
Abuildup oficeon thesatelliteradioantenna can
affect satellite radio performance. Remove the
ice to restore satellite radio reception.
