2003 Lexus GX470 radio

AUDIO
216FM
Fading and
drifting stations − Generally, the ef fective range
of FM is about 40 km (25 miles). Once outside this range, you
may notice fading and drifting, which increase with the distance
from the radio transmitter. They are often accompanied by
distortion.
Multipath − FM signals are reflective, making it possible for
two signals to reach your antenna at the same time. If this
happens, the signals will cancel each other out, causing a
momentary flutter or loss of reception.
Static and fluttering − These occur when signals are blocked
by buildings, trees, or other large objects. Increasing the bass
level may reduce static and fluttering.
Station swapping − If the FM signal you are listening to is
interrupted or weakened, and there is another strong station
nearby on the FM band, your radio may tune in the second
station until the original signal can be picked up again. AM
Fading
− AM broadcasts are reflected by the upper
atmosphere − especially at night. These reflected signals can
interfere with those received directly from the radio station,
causing the radio station to sound alternately strong and weak.
Station interference − When a reflected signal and a signal
received directly from a radio station are very nearly the same
frequency, they can interfere with each other, making it dif ficult
to hear the broadcast.
Static − AM is easily af fected by external sources of electrical
noise, such as high tension power lines, l ightening, or electrical
motors. This results in static.
Caring for your cassette player and tapes
For the best performance for your cassette player and tapes:
Clean the tape head and other parts regularly.
 A dirty tape head or tape path can decrease sound quality
and tangle your cassette tapes. The easiest way to clean
them is by using a cleaning tape. (A wet type is
recommended.)

To clean a compact disc: Wipe it with a soft, lint−free cloth
that has been dampened with water. Wipe in a straight line
from the center to the edge of the disc (not in a circle). Do not
use a conventional record cleaner or anti −static device.
