CHECK DISC:
· Confirm that the CD is inserted cor-
rectly (the label side is facing up,
etc.).
· Confirm that the CD is not bent or
warped and it is free of scratches.
PUSH EJECT:
This is a malfunction due to excessive
temperature inside the player. Remove
the CD by pushing the EJECT button. Af-
ter a short time, reinsert the CD. The CD
can be played when the temperature of
the player returns to normal.
UNPLAYABLE:
The file is unplayable in this audio sys-
tem (only MP3 or WMA CD). Compact Disc (CD) with MP3 or
WMA Explanation of terms:
O MP3 Ð MP3 is short for Moving Pic-
tures Experts Group Audio Layer 3.
MP3 is the most well-known com-
pressed digital audio file format. This
format allows for near ªCD qualityº
sound, but at a fraction of the size of
normal audio files. MP3 conversion of
an audio track from CD-ROM can re-
duce the file size by approximately
10:1 ratio with virtually no perceptible
loss in quality. MP3 compression re-
moves the redundant and irrelevant
parts of a sound signal that the
human ear doesn't hear.
O WMA Ð Windows Media Audio (WMA)
is a compressed audio format created
by Microsoft as an alternative to MP3.
The WMA codec offers greater file
compression than the MP3 codec, en-
abling storage of more digital audio
tracks in the same amount of space
when compared to MP3s at the same
level of quality.
O Bit rate Ð Bit rate denotes the number
of bits per second used by a digital
music file. The size and quality of a compressed digital audio file is deter-
mined by the bit rate used when en-
coding the file.
O Sampling frequency Ð Sampling fre-
quency is the rate at which the
samples of a signal are converted
from analog to digital (A/D conversion)
per second.
O Multisession Ð Multisession is one of
the methods for writing data to media.
Writing data once to the media is
called a single session, and writing
more than once is called a multises-
sion.
O ID3/WMA Tag Ð The ID3 tag is the
part of the encoded MP3 or WMA file
that contains information about the
digital music file such as song title,
artist, album title, encoding bit rate,
track time duration, etc. ID3 tag infor-
mation is displayed on the
Album/Artist/Track title line on the
display.
