RADIO
Push the power switch to the "ACC" or "ON"
position and push the radio band select button
to turn on the radio. If you listen to the radio with
the READY to drive indicator light is OFF, the
power switch should be pushed to the "ACC"
position.
Radio reception is affected by station signal
strength, distance from radio transmitter, build-
ings, bridges, mountains and other external
influences. Intermittent changes in reception
quality normally are caused by these external
influences.
Using a cellular phone in or near the
vehicle may influence radio reception
quality.
Radio reception
Your NISSAN radio system is equipped with
state-of-the-art electronic circuits to enhance
radio reception. These circuits are designed to
extend reception range, and to enhance the
quality of that reception.
However there are some general characteristics
of both FM and AM radio signals that can affect
radio reception quality in a moving vehicle, even
when the finest equipment is used. These
characteristics are completely normal in a given
reception area, and do not indicate any mal-
function in your NISSAN radio system.
Reception conditions will constantly change
because of vehicle movement. Buildings, terrain,
signal distance and interference from other
vehicles can work against ideal reception.
Described below are some of the factors that
can affect your radio reception.
Some cellular phones or other devices may
cause interference or a buzzing noise to come
from the audio system speakers. Storing the
device in a different location may reduce or
eliminate the noise.
While charging the vehicle, radio programs may
not be tuned in to because the reception of the
radio becomes weak.
FM radio reception
Range: FM range is normally limited to 25 to 30
miles (40 to 48 km), with monaural (single
station) 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, exhibiting
many of the same characteristics as light. For
example they will reflect off objects.
Fade and drift: As your vehicle moves away from
a station transmitter, the signals will tend to fade
and/or drift.
Static and flutter: During signal 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 lowering the
treble setting to reduce the treble response.
Multipath reception: Because of the reflective
characteristics of FM signals, direct and re-
flected signals reach the receiver at the same
time. The signals may cancel each other,
resulting in momentary flutter or loss of sound.
