USER MANUAL - DMW300 NETWORK | FM | USB RECEIVER & PLAYER
2.2. Functional Description
The DMW300 is both a receiver for internet radio and terrestrial FM radio, as well as a USB and
network media player to play the music library stored in any of the computers in the local network that
are compatible with the UPnP (Universal Plug and Play) media sharing protocol. The DMW300 is
specifically catering for background music replay in commercial venues and as such allows easy
access to preset sources, while system settings are not easily accessible by the operator to avoid
accidental change of settings by unqualified operators; this is achieved by two different user levels,
named SOURCE_MENU (SRC) mode and SET_MENU (SET) mode. The DMW300 can be connected
to a wired network or a wireless network via an optional USB WiFi adapter. An IR remote control is
available for the main functions.

nel.
