RADIO
Turn the ignition key to ACC or ON and
press the power on switch to turn on the
radio. If you listen to the radio with the
engine not running, the key should be
turned to the ACC position.
Radio reception is affected by station signal
strength, distance from radio transmitter,
buildings, bridges, mountains and other ex-
ternal 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 en-
hance radio reception. These circuits are
designed to extend reception range, and to
enhance the quality of that reception.
However there are some general character-
istics of both FM and AM radio signals that
can affect radio reception quality in a mov-
ing vehicle, even when the finest equipment
is used. These characteristics are com-pletely normal in a given reception area,
and do not indicate any malfunction 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.
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, 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 antennaposition, usually in conjunction with in-
creased distance from the station transmit-
ter, static or flutter can be heard. This can
be reduced by adjusting the treble control
counterclockwise to reduce treble re-
sponse.
Multipath reception: Because of the reflec-
tive characteristics of FM signals, direct and
reflected signals reach the receiver 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 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 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 turbu-

When installing a CB ham radio or a car
phone in your NISSAN, be sure to observe
the following cautions, otherwise the new
equipment may adversely affect the Multi-
port Fuel Injection (MFI) system and other
electronic parts.
WARNING
cA cellular telephone should not be
used while driving so full attention
may be given to vehicle operation.
Some jurisdictions prohibit the use
of cellular telephones while driving.
cIf you must make a call while your
vehicle is in motion, the hands free
cellular phone operational mode (if
so equipped) is highly recom-
mended. Exercise extreme caution
at all times so full attention may be
given to vehicle operation.
cIf a conversation in a moving vehicle
requires you to take notes, pull off
the road to a safe location and stop
your vehicle before doing so.
CAUTION
cKeep the antenna as far away as
possible from the Engine Control
Module (ECM).
c
Keep the antenna wire more than 8 in.
(20 cm) away from the Multiport Fuel
Injection harness. Do not route the
antenna wire next to any harness.
cAdjust the antenna standing-wave
ratio as recommended by the manu-
facturer.
cConnect the ground wire from the
CB radio chassis to the body.
cFor details, consult an authorized
NISSAN dealer.
