FM
Fading and drifting stations — General-
ly, the effective range of FM is about 40 km
(25 miles). Once outside this range, you
may notice fading and drifting, which in-
crease with the distance from the radio
transmitter. They are often accompanied
by distortion.
Multi path — FM signals are reflective,
making it possible for two signals to reach
your antenna at the same time. If this hap-
pens, 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 flut-
tering.
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 inter-
fere 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 difficult to hear the broad-
cast.
Static — AM is easily affected by external
sources of electrical noise, such as high
tension power lines, lightening, or electri-
cal motors. This results in static. MP3/WMA files
MP3 (MPEG Audio Layer 3) and WMA
(Windows Media Audio) are audio
compression standards.
The MP3/WMA player can play MP3
and WMA files on CD
−ROM, CD−R
and CD −RW discs.
The unit can play disc recordings com-
patible with ISO 9660 level 1 and level
2 and with the Romeo and Joliet file
system.
When naming an MP3 or WMA file, add
the appropriate file extension (.mp3 or
.wma).
The MP3/WMA player plays back files
with .mp3 or .wma file extensions as
MP3 or WMA files. To prevent noise
and playback errors, use the appropri-
ate file extensions.
The player can play only the first ses-
sion using multi −session compatible
CDs.
MP3 files are compatible with the ID3
Tag Ver. 1.0, Ver. 1.1, Ver. 2.2, and Ver.
2.3 formats. The unit cannot display
disc title, track title and artist name in
other formats.
WMA files can contain a WMA tag that
is used in the same way as an ID3 tag.
WMA tags carry information such as
track title, artist name.
The emphasis function is available
only when playing MP3/WMA files re-
corded at 32, 44.1 and 48 kHz. (The
system can play MP3 files with sam-
pling frequencies of 16, 22.05, and 24
kHz. However, the emphasis function
is not available for files recorded at
these frequencies.)
