Fading: AM broadcasts are reflected by
the upper atmosphere — especially at
night. These reflected signals can interfere
with those received directly from the radio
station, causing the radio station to sound
alternately strong and weak.
Station interference: When a reflected sig-
nal and a signal received directly from a ra-
dio 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 electrical
motors. This results in static.

(Variable Bit Rate (VBR) compatible)
MP3 (MPEG Audio Layer 3), WMA
(Windows Media Audio) and AAC
(Advanced Audio Coding) are audio com-
pression standards.
 This system can play MP3/WMA/AAC files
on USB memory.
 MP4, WMV and AVI files can use the fol-
lowing resolutions: 128×96, 160×120,
176×144 (QCIF), 320×240 (QVGA),
352×240 (SIF), 352×288 (CIF), 640×480
(VGA), 720×480 (NTSC), 720×576 (PAL)
 When naming an MP3/WMA/AAC file, add
an appropriate file extension (.mp3/.wma/
.m4a).
 This system plays back files with .mp3/
.wma/.m4a file extensions as MP3/WMA/
AAC files respectively. To prevent noise
and playback errors, use the appropriate
file extension.
 MP3 files are compatible with the ID3 Tag
Ver. 1.0, Ver. 1.1, Ver. 2.2 and Ver. 2.3 for-
mats. This system cannot display album
title, track title and artist name in other for-
mats.
 WMA/AAC files can contain a WMA/AAC
tag that is used in the same way as an ID3
tag. WMA/AAC tags carry information
such as track title and artist name.
 The emphasis function is available only
when playing MP3/WMA files recorded at
32, 44.1 and 48 kHz.
 This system can play back AAC files
encoded by iTunes.
 The sound quality of MP3/WMA files gen-
erally improves with higher bit rates. In
order to achieve a reasonable level of
sound quality, files recorded with a bit rate
of at least 128 kbps are recommended.

MP3i (MP3 interactive) and MP3PRO for-
mats are not compatible with the audio
player.
 The player is compatible with VBR (Vari-
able Bit Rate).
 When playing back files recorded as VBR
(Variable Bit Rate) files, the play time will
not be correctly displayed if the fast for-
ward or reverse operations are used.
 It is not possible to check folders that do
not include MP3/WMA/AAC files.
 MP3/WMA/AAC files in folders up to 8 lev-
els deep can be played.
 The order changes depending on the per-
sonal computer and MP3/WMA/AAC
encoding software you use. 
This is a general term that describes the
process of writing data on-demand to CD-
R, etc., in the same way that data is writ-
ten to floppy or hard discs.
 This is a method of embedding track-
related information in an MP3 file. This
embedded information can include the
track number, track title, the artist’s name,
the album title, the music genre, the year
of production, comments, cover art and
other data. The contents can be freely
edited using software with ID3 tag editing
functions. Although the tags are restricted
to a number of characters, the information
can be viewed when the track is played
back.
 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
and artist name.

MP3 is an audio compression standard
determined by a working group (MPEG) of
the ISO (International Standard Organiza-
tion). MP3 compresses audio data to
about 1/10 the size of that on conventional
discs.
 WMA (Windows Media Audio) is an audio
compression format developed by
Microsoft
®. It compresses files into a size
smaller than that of MP3 files. The decod-
ing formats for WMA files are Ver. 7, 8 and
9.
