3 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).
4 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.
4.2 Audio output
If required, connect other stereo headphones
with an impedance of
≥
32 Ω, the input of an
amplifier, or a pair of active speakers to the
3.5 mm stereo jack
(5). Thus, the hearing
capsules of the MD-3000P are switched off.
4.3 Computer
For data exchange with a computer connect its
USB port via the supplied cable to the jack
(6). The display (2) shows
.
4.4 Power supply
For power supply a rechargeable lithium ion
battery is installed. The charging status can be
read from the battery symbol (a) on the display
(2) during the replay mode. To recharge this bat-
tery:
1) Connect the USB jack
(6) via the sup-
plied cable to a computer or a special power
supply unit with USB port (e. g. PS-1005USB
from MONACOR). The display shows
.
2) Set the on/off switch (7) to ON.
Audio replay is not possible when recharging.
If the charging process is terminated, the
LED (8) lights up (max. charging time 5 h).
If the unit is to be put out of operation
definitively, take it to a local recycling
plant for a disposal which is not harm-
ful to the environment.
