4.0 Operation
4.1 Overview
4.1.1 Only standard CDs can be recorded to the flash memory. Discs
containing MP3 songs can not be recorded to the flash memory,
but they can be played.
4.1.2 Recording speed is 4X faster than playback speed. A four (4)
minute song will record in about one (1) minute. A 60 minute CD
will record in about 15 minutes.
4.1.3 There are two recording bitrates (32 kbps and 64 kbps). The higher
bitrate is better quality but requires twice the amount of memory.
You can record some songs at one bitrate and other songs at a
different bitrate. The bitrate can be changed in the setup menus.
The Record Quality of previously recorded songs can not be
changed. The song must be deleted and re-recorded to change the
Record Quality of a song.
4.1.4 The flash memory can store about 450 minutes of music at 32 kbps
bitrate or about 225 minutes at 64 kbps bitrate.
4.1.5 Songs can not be played from the CD while the CD is recording,
however a work around is described in Section 4.5.
4.1.6 CD songs are stored in a unique directory labeled DIR_XX. When
songs from a new CD are recorded they will be stored in the next
sequential directory. Songs from the same CD will always be
recorded in the same directory.
4.1.7 CD song tracks are labeled TrackXX.cda. Songs stored in flash
memory are labeled TrackXX.aac. The song number (XX) when
recorded will remain the same as it is on the CD. So if Track05.cda
is recorded from the CD, it will be labeled Track05.aac in the flash
memory.
4.2 General Operation Information

•Insert CD to record
•From the Main Menu select RECORDALL to start recording the
entire CD to memory, or select RECORDTrackXX to start recording
a particular track.
•While recording, songs stored in flash memory can be played. Songs
on the CD can not be played while recording from the CD.
•If none of the songs on the CD have previously been recorded to
memory, a new directory will be created and the songs will be stored in
that directory.
•If some songs from the CD were already recorded to a directory in
memory, any new songs recorded from that CD will be added to that
directory.
•If all the songs on the CD are already recorded to memory, the
recording task will complete immediately, because all the songs are
already stored. You can not record the same song from the same CD
multiple times to memory.
•If it is desired to record the same song at a different bitrate, the song
must first be deleted from memory and then recorded again.
Playing songs from a CD while recording the same CD
•You can not play songs from a CD while recording from the CD.
However, since recording is 4X faster than playing, you can start
recording a CD then immediately start playing the first track of the CD
from flash memory. In this way, you can play the CD songs while it’s
recording but you are actually playing from flash memory, not the CD.
Recording progress appears
in the upper right hand corner.
