■AM characteristics
AM signals bend around such things as buildings or mountains and
bounce off the ionosphere.
Therefore, they can reach lon ger distances than FM signals.
Because of this, 2 stations may sometimes be picked up on the
same frequency at the same time.

Station 2
■FM characteristics
An FM broadcast range is usually about 25 - 30 miles (40 - 50 km)
from the source. Because of extra coding needed to break the
sound into 2 channels, stereo FM has even less range than monau -
ral (non-stereo) FM.

Interior Features
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 distance s
possible with AM reception.

Obstruction
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 reflect ed 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 p roximity to the transmitter.
Direct
Reflected wave
● Flutter/Skip noise
Signals from an FM transmit-
ter move in straight lines and
become weak in valleys
between tall buildings, moun-
tains, 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 charac-
terized by sound breakup.

Interior Features
●Strong signal noise
This occurs very close to a
transmitter tower. The broad-
cast 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 o f 2 strong stations broadcast-
ing at similar frequencies, the original station may be tempora rily
lost and the second station picked up. At this time there will be
some noise from this disturbance.

MP3 stands for MPEG Audio Layer 3, which is standardized voice
compression establ ished by the ISO
*1 working group (MPEG).
Use of MP3 allows for audio data to be compressed to approximat ely
a tenth of the source data size.
This unit plays files with the extension (.mp3) as MP3 files.

• 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.

AAC stands for Advanced Audio Coding, which is standardized voice
compression established by the ISO
*1 working group (MPEG). Audio
data can be created and stored at a higher compression ratio th an
MP3.
This unit plays files with the extensions (.aac/.m4a/.wav) as t he AAC
files.
• AAC files written under specifications other than the indicate d spec-
ification may not play normally or files or folder names may no t dis-
play correctly.
