2005 Acura MDX Sound

You can use the instrument panel
brightness control knob to adjust the
illumination of the audio system (see
page ). The audio system
illuminates when the parking lights
are on, even if the radio is turned of f .
Those bands cover these f requen-
cies:
AM band: 530 to 1,710 kilohertz
FM band: 87.7 to 107.9 megahertzStations must use these exact
f requencies. It is f airly common f or
stations to round-of f the f requency in
their advertising, so your radio could
display a f requency of 100.9 even
though the announcer may identif y
the station as ‘‘FM101.’’
A radio station’s signal gets weaker
as you get f arther away f rom its
transmitter. If you are listening to an
AM station, you will notice the sound
volume becoming weaker and the
stationdriftinginandout.If youare
listening to an FM station, you will
see the stereo indicator f lickering of f
and on as the signal weakens.
Eventually, the stereo indicator willgo of f and the sound will f ade
completely as you get out of range of
the station’s signal.
Driving very near the transmitter of
a station that is broadcasting on a
f requency close to the f requency of
the station you are listening to can
also af f ect your radio’s reception.
You may temporarily hear both
stations,orhearonlythestationyou
are close to.
Your vehicle’s radio can receive the
complete AM and FM bands.
How well your vehicle’s radio
receives stations is dependent on
many f actors, such as the distance
from the station’s transmitter,
nearby large objects, and
atmospheric conditions.
Radio stations on the AM band are
assigned f requencies at least ten
kilohertz apart (530, 540, 550).
Stations on the FM band are
assigned f requencies at least 0.2
megahertz apart (87.9, 88.1, 88.3). 76

Radio signals, especially on the FM
band, are def lected by large objects
such as buildings and hills. Your
radio then receives both the direct
signal f rom the station’s transmitter,
and the def lected signal. This causes
the sound to distort or flutter. This is
a main cause of poor radio reception
in city driving.Radio reception can be af f ected by
atmospheric conditions such as
thunderstorms, high humidity, and
even sunspots. You may be able to
receive a distant radio station one
day and not receive it the next day
because of a change in conditions.
Electrical interf erence f rom passing
vehicles and stationary sources can
cause temporary reception problems.
As required by the FCC:
Changes or modif ications not expresslyapproved by the party responsible f orcompliance could void the user’sauthority to operate the equipment.
