Fading and drifting:
FM range is limited to about 40 km (25 miles), except for
some high power stations.
If a vehicle is moving away from the desired station's
transmitter, the signal will tend to fade and/or drift. This
phenomenon is more noticeable with FM than with AM,
and is accompanied by distortion.
Fading and drifting can be minimized to a certain degree
by careful attention to fine tuning, or you should retune the
radio to another stronger station.

Static and Fluttering:
When the line±of±sight link between a transmitter and
vehicle is blocked by large buildings or the like, the radio
sound may be accompanied by static or fluttering because
of the characteristic of FM. In a similar effect, a fluttering
noise is sometimes heard when driving along a tree±lined
road.
This static and fluttering can be reduced by adjusting the
tone control for greater bass response until the disturbance
has passed.

Multipath:
Because of the reflecting characteristics of FM, direct and
reflected signals may reach the antenna at the same time
(multipath) and cancel each other out. As a vehicle moves
through these electronic dead spots, the listener may hear
a momentary flutter or loss of reception.

Station swapping:
When two FM stations are close to each other, and an
electronic dead spot, such as static or multipath area,
interrupts the original signal, sometimes the stronger
second signal will be selected automatically until the
original one returns. This swapping can also occur as you
drive away from the selected station and approach another
station with a stronger signal.

 NR*, push the right
side of the ( B C) button to select the Dolby B

The Dolby C NR mode reduces tape noise by another 10 dB
or about 20 dB total. For best sound reproduction, select the
same NR mode that was used to record the tape. To play a tape
recorded without Dolby NR*, push the button until the Dolby
NR indicator disappears.

a. Look carefully at the fuse. If the thin wire is broken, the
fuse has blown. If you are not sure or if it is too dark to see,
try replacing the suspected fuse with one of the same value
that you know is good.
b. Only install a fuse with the amperage rating designated on
the fuse box lid.
If you do not have a spare fuse, in an emergency you can pull
out the ºCIGº, ºRADIO NO.1º, ºDOMEº or ºHTRº fuse,\
which may be dispensable for normal driving, and use it if its
amperage rating is the same.
If you cannot use one of the same amperage, use one lower
than, but as close as possible to, the amperage. If the
amperage is lower than that specified, the fuse might blow out
again but this does not indicate anything wrong. Be sure to
get the correct fuse as soon as possible and return the
substitute to its original clips. It is a good idea to purchase a set of spare fuses and keep them
in your vehicle for emergencies.
If the new fuse immediately blows out, there is a problem with
the electrical system. Have your Lexus dealer correct it as
soon as possible.
