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
adjusting the treble control counterclockwise
to reduce 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.
The radio has an FM Diversity reception sys-
tem, which employs two antennas if so
equipped. One is a rod type antenna; the other
is an antenna printed on the window. This
system automatically switches to the antenna
which is receiving less noise.

in this section.AM RADIO RECEPTIONAM 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. AMsignals 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 sev-
eral seconds during ionospheric turbulence
even in areas where no obstacles exist.
Static: Caused by thunderstorms, electrical
power lines, electric signs and even traffic
lights.
AUDIO OPERATION
PRECAUTIONS
Cassette playerITo maintain good quality sound,
NISSAN recommends using cassette
tapes of 60 minutes or shorter in length.
ICassette tapes should be removed from
the player when not in use. Store cas-
settes in their protective cases and away
from direct sunlight, heat, dust, mois-
ture and magnetic sources.
IDirect sunlight can cause the cassette to
become deformed. The use of deformed
cassettes may cause the cassette to jam
in the player.
IDo not use cassettes with labels whichare peeling and loose. If used, the label
could jam in the player.
IIf a cassette has loose tape, insert a
pencil through one of the cassette hubs
and rewind the tape firmly around the
hubs. Loose tape may cause tape jam-
ming and wavering sound quality.
IOver a period of time, the playback
head, capstan and pinch roller may col-
lect a tape coating residue as the tape is
played. This residue accumulation can
cause weak or wavering sound, and
should be removed periodically with a
head cleaning tape. If the residue is not
removed periodically, the player may
need to be disassembled for cleaning.
