Playback of MP3/WMA Files
When a medium containing MP3/WMA data is loaded,
the radio checks all files on the medium. If the medium
contains a lot of folders or files, the radio will take more
time to start playing the MP3/WMA files.
Loading times for playback of MP3/WMA files may be
affected by the following:
²Media - CD-RW media may take longer to load than
CD-R media
²Medium formats - Multisession discs may take longer
to load than non-multisession discs
²Number of files and folders - Loading times will
increase with more files and folders
To increase the speed of disc loading, it is recommended
to use CD-R media and single-session discs. To create a
single-session disc, enable the Disc at Once option before
writing to the disc.
