Applications
The MD-3000P, stereo headphones with inte-
grated MP3 player, allows to enjoy music every-
where without disturbing cable. It plays MP3
audio files from SD or MMC memory cards. Via
the USB connection it is possible to easily ex-
change data between the inserted memory card
and a computer.
The MD3000P is supplied with power via an
installed rechargeable lithium ion battery which
can be recharged via the USB jack. This can
e. g. be made when exchanging data with a
computer or via a special power supply unit with
USB output (e. g. PS-1005USB from MONA-
COR).

Connection
4.1 Memory card
Memory cards of type SD (Secure Digital Mem-
ory Card) or MMC (Multimedia Card) with a ca-
pacity of 4 GB max. can be used. The cards
have to be formatted with the file system FAT16
or FAT32.
As shown in fig. 1, insert the memory card
into the slot (1) until it engages. For access to
the card via the USB interface of a computer,
the write protect tab at the card must not be in
position LOCK. For the moment, slightly push in
the card for removing it; then it is slightly slid
outwards by a spring and can be seized more
easily for removing it.
With the unit switched on or with existing
connection to a computer the card should not be
removed, otherwise data loss may occur.
