PLAYING MP3 FILES
MP3 Explorer is the application which is used to download
1
into a portable MP3 player and play any music file with
extensions of MP3 (*.mp3) or CA (*.ca) stored in PC. If you
download any music file whose extension is CA, it detects
the ID of multimedia card (MMC), changes its extension to
GU3, and saves it. This protects against unauthorized
reproduction, which is required by the organizations related
to copyright of music. You can play downloaded music files
with the extension of GU3 in the MP3 player with the sound
quality of CD . Music files with the extension of GU3 stored
on this multimedia card can be played in any MP3 players
made by Zenith Electronics Corporation. But, in the case
that you upload any music file with the extension of GU3
onto PC, you will not be able to play these music files.
If you upload onto PC any GU3 (*.GU3) file which has been
2
downloaded into an MP3 player, and then, download it into
another card, it will not be played or playback will be broken
up, due to the reproduction prevention lock.
