VHF, Black Box w/Grey CommandMic IV

Product Overview

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 COMMANDMIC^TM 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-195B/SW (1m depth for 30 minutes)
Dual/tri-watch function for monitoring Ch.16 and/or call channel
Priority and normal scan
