Things You Need to Know
WA R N I N G
Always adjust the audio while the vehicle is
stopped:
Do not adjust the audio control switches
while driving the vehicle. Adjusting the
audio while driving the vehicle is
dangerous as it could distract your
attention from the vehicle operation which
could lead to a serious accident.
Even if the audio control switches are
equipped on the steering wheel, learn to
use the switches without looking down at
them so that you can keep your maximum
attention on the road while driving the
vehicle.
CAUTION
For the purposes of safe driving, adjust the
audio volume to a level that allows you to
hear sounds outside of the vehicle
including car horns and particularly
emergency vehicle sirens.
NOTE
•To prevent the battery from being
discharged, do not leave the audio
system on for a long period of time when
the engine is not running.
•If a cellular phone or CB radio is used
in or near the vehicle, it could cause
noise to occur from the audio system,
however, this does not indicate that the
system has been damaged.
Do not spill any liquid on the audio
system.
▼ Radio Reception
AM characteristics
AM signals bend around such things as
buildings or mountains and bounce off the
ionosphere.
Therefore, they can reach longer distances
than FM signals.
Because of this,
two stations may
sometimes be picked up on the same
frequency at the same time.
Station 2
Station 1 Ionosphere

FM characteristics
An FM broadcast range is usually about
40―50 km (25―30 miles) from the
source. Because of extra coding needed to
break the sound into two channels, stereo
FM has even less range than monaural
(non-stereo) FM.
FM Station
40—50km
(25—30 miles)
Signals from an FM transmitter are similar
to beams of light because they do not bend
around corners, but they do reflect. Unlike
AM signals, FM signals cannot travel
beyond the horizon. Therefore, FM
stations cannot be received at the great
distances possible with AM reception.
AM wave
FM wave
FM wave
100—200 km (60—120 miles) Ionosphere
Atmospheric conditions can also affect
FM reception. High
humidity will cause
poor reception. However, cloudy days may
provide better reception than clear days.
Multipath noise
Since FM signals can be reflected by
obstructions, it is possible to receive both
the direct signal and the reflected signal at
the same time. This causes a slight delay
in reception and may be heard as a broken
sound or a distortion. This problem may
also be encountered when in close
proximity to the transmitter.
Reflected wave
Direct
Flutter/Skip noise
Signals from an FM transmitter move in
straight lines and become weak in valleys
between tall buildings, mountains, and
other obstacles. When a vehicle passes
through such an area, the reception
conditions may change suddenly, resulting
in annoying noise.

Weak signal noise
In suburban areas, broadcast signals
become weak because of distance from the
transmitter. Reception in such fringe areas
is characterized by sound breakup.
Strong signal noise
This occurs very close to a transmitter
tower. The bro adcast signals are extremely
strong, so the result is noise and sound
breakup at the radio receiver.
Station drift noise
When a vehicle reaches the area of two
strong stations broadcasting at similar
frequencies, the original station may be
temporarily lost and the second station
picked up. At this time there will be some
noise from this disturbance.
Station 2
88.3 MHz
Station 1
88.1 MHz

Operating Tips for MP3
MP3 stands for MPEG Audio Layer 3,
which is standardized voice compression
established by the ISO
*1 working group
(MPEG).
Use of MP3 allows for audio data to be
compressed to approximately a tenth of
the source data size.
This unit plays files with the extension
(.mp3) as MP3 files.
*1 International Organization for
Standardization
CAUTION
Do not use an audio file extension on files
other than audio files. In addition, do not
change the audio file extension. Otherwise,
the unit will not recognize the file correctly
resulting in noise or a malfunction.

•When naming an MP3 file, be sure to
add an MP3 file extension (.mp3) after
the file name.

•The number of characters which can be
displayed is restricted.▼Operating Tips for WMA
WMA is short for Windows Media*1
Audio and is the audio compression
format used by Microsoft
*1.
Audio data can be created and stored at a
higher compression ratio than MP3.
This unit plays files with the extension
(.wma) as WMA files.

CAUTION
Do not use an audio file extension on files
other than audio files. In addition, do not
change the audio file extension. Otherwise,
the unit will not recognize the file correctly
resulting in noise or a malfunction.
•WMA files written under specifications
other than the indicated specification
may not play normally or files or folder
names may not display correctly.
•The file extension may not be provided
depending on the computer operating
system, version, softw are, or settings. In
this case, add the file extension “.wma”
to the end of the file name, and then
write it to the memory.
