Your vehicle’s radio receives both AM and
FM stations.
The quality of your reception is affected by
distance, obstacles, and signal interference.
This radio complies with Part 15 of Federal
Communications Commission (FCC) Rules
(for vehicles sold in U.S.A.). Operation is
subject to the following conditions:
 The device may not cause harmful inter-
ference.
 This device must accept any interference
recieved, including interference that may
cause undesirable operation.
FM signals do not follow the earth surface
nor are they reflected by the upper atmo-
sphere. For this reason, FM broadcasts cannot
be received over long distances. AM signals
follow the earth’s surface and are reflected by
the upper atmosphere. For this reason, AM
broadcasts can be received over longer dis-
tances.
Because of the limited range of FM signals
and the way FM waves transmit, you may
experience weak or fading FM reception.
When the broadcast is blocked by mountains
or similar obstructions, reception can be dis-
turbed.
The reason why one can hear FM but not AM
in parking garages, under bridges etc., is that
FM signals, unlike AM signals, are reflected
by solid objects such as buildings, etc.
Because FM signals are easily reflected by
buildings, this can also cause reception dis-
turbances.
The direct signal from the broadcast station
reaches the antenna slightly before the
reflected signal. This time difference may
cause some reception disturbance or flutter.
This problem occurs primarily in urban areas.
• When driving into a structure that has a low
ceiling
