Black Box Transceiver - Icom Quality. Small Footprint. Space-saving, two-piece configuration The IC-M400BB consists of a two-piece, black box configuration. All function control including DSC operation, can be made from the COMMANDMICIV™, HM-195B/SW, and the RF unit, IC-M400BB, can be installed in an out-of-sight place. New intuitive user interface The new menu system is shared with Icom's latest models. The bottom line of the dot-matrix display shows the software key functions which can be toggled with the left and right buttons. Active noise cancelling The built-in bidirectional active noise cancelling reduces background noise to up to 90% and improves both your transmitted voice and incoming call. Hear and be heard more clearly. 10W Loud Audio, Public Address and Foghorn The IC-M400BB has a built-in 10W amplifier that increases the audio output from an additional external speaker. The public address function allows you to make an announcement from the microphone like a loud speaker, and the foghorn can also be emitted from the external speaker. Built-in Class D DSC The built-in DSC watch function monitors Ch. 70 (DSC channel) activity, even while you are receiving another channel. DSC functions include: distress, individual, group, all ships, urgency, safety, position request/report, polling request and DSC test calls. Common NMEA Interface When connected to an external GPS receiver, current position and time are shown on the COMMANDMICTM display. When receiving DSC information from another vessel, the radio can transfer it to a navigational device via NMEA 0183 connectivity. AIS Target Call with MA-500TR When connected to the optional MA-500TR Class B AIS transponder, the AIS target call function allows you to set up an individual DSC call from the MA-500TR. Additional features include - MarineCommander™ compatible
- AquaQuake™ water draining function
- IPX7 submersible protection both for IC-M400BB and HM-195SW (1m depth for 30 minutes)
- Dual/tri-watch function for monitoring Ch.16 and/or call channel
- Priority and normal scan
