AUDIO SYSTEM
Static and fluttering — These occur when
signals are blocked by buildings, trees, or oth-
er large objects. Increasing the bass level
may reduce static and fluttering.
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 interfere 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 ra-
dio station are very nearly the same frequen-
cy, they can interfere with each other, making
it difficult to hear the broadcast.
Static — AM is easily affected by external
sources of electrical noise, such as high ten-
sion power lines, lightening, or electrical mo-
tors. This results in static.

MP3/WMA files
MP3 (MPEG Audio Layer 3) and WMA
(Windows Media Audio) are audio com-
pression 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 compat-
ible 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 play-
back errors, use the appropriate file ex-
tensions.
The player can play only the first session
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 for-
mats. 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 recorded at
32, 44.1 and 48 kHz. (The system can
play MP3 files with sampling frequencies
of 16, 22.05, and 24 kHz. However, the
emphasis function is not available for files
recorded at these frequencies.)
The sound quality of MP3/WMA files gen-
erally improves with higher bit rates. In or-
der to achieve a reasonable level of sound
quality, discs recorded with a bit rate of at
least 128 kbps are recommended.
Playable bit rates
MP3 files:
MPEG1 LAYER3—64 to 320 kbps
MPEG2 LSF LAYER3—64 to 160 kbps
WMA files:
Ver. 7, 8 CBR—48 to 192 kbps
Ver. 9 CBR—48 to 320 kbps
The MP3/WMA player does not play back
MP3/WMA files from discs recorder using
packet write data transfer (UDF format).
Discs should be recorded using "pre−
mastering" software rather than packet−
write software.
The m3u playlists are not compatible with
the audio player.
MP3i (MP3 interactive) and MP3PRO for-
mats are not compatible with the audio
player.
