MP3 and WMA files
MP3 (MPEG Audio LAYER3) is a standard audio compression format.
Files can be compressed to approximately 1/10 of their original size by using
MP3 compression.
WMA (Windows Media Audio) is a Microsoft audio compression format.
This format compresses audio data to a size smaller than that of the MP3
format.
MP3 file compatibility
A high compression rate can adversely affect sound quality.
The CD player can read up to 255 MP3 files spread over 8 folder levels
with a maximum of 192 folders. However, it is recommended that this be
kept to 2 levels so as to limit the time taken to access and play the CD.
While playing, the folder structure is not observed.
Playlists
The types of playlists that are accepted: “.m3u” and “.wpl”.
The number of files recognized is limited to 5000 in 500 folders on a maxi-
mum of 8 levels.

USB memory functions
Depending on the USB memory that is connected to the system, the
device itself may not be operable and certain functions may not be avail-
able. If the device is inoperable or a function is unavailable due to a mal-
function (as opposed to a system specification), disconnecting the device
and reconnecting it once again may resolve the problem.
If the USB memory still does not begin operation after being discon-
nected and reconnected, format the memory.
The system creates playlists (temporary memory), the creation time for
which this can take, can be from a few seconds to several minutes. The
playlists are updated every time the ignition is switched off or a USB
memory stick is connected. Play starts automatically after a period, which
depends on the capacity of the USB memory stick.
At a first connection, the order suggested is by folder. When connecting
again, the order previously chosen is retained.
