Icom IC-M506

Icom IC-M506

Integrated AIS Receiver*

With an integrated AIS receiver, Icom IC-M506 can show real-time AIS vessel traffic information on the display. The AIS target call function allows you to easily set up a DSC individual call. The Plotter, Target list and Danger list can be toggled on the display.
* AIS receiver and NMEA 2000 interface units are options, depending on version.

NMEA 2000™ Connectivity*

With the plug-and-play functionality of NMEA 2000, the IC-M506 can easily connect to a NMEA 2000 network. The IC-M506 can receive and transmit GPS (position, course (COG) and speed (SOG)), AIS report and DSC call information data and transmit radio frequency and PGN list data on the network. Using this function, the IC-M506 can convert NMEA 0183 GPS data to NMEA 2000 data for other equipment.
* AIS receiver and NMEA 2000 interface units are options, depending on version.

Last Call Voice Recording

The last call voice recording function automatically saves the last two minutes of the last incoming call. You can replay the received call, and not miss any incoming call.

Active Noise Cancelling

Using digital signal processing technology, the built-in bidirectional active noise cancelling provides superb performance. It reduces background noise to up to 90% in the received signal and 30% fixed in the transmitting signal. The function OFF setting is also possible.

Intuitive Menu-Driven User Interface

The intuitive software key functions provide easy and fast operation to control the multiple functions of the IC-M506. The bottom line of the dot-matrix display shows the software key functions which can be toggled with the left and right buttons.

25W Two-Way Hailer

When connected to an external hailer horn, you can talk to people on the deck or shore from the radio’s microphone and can hear people’s reply via the hailer speaker. The RX hailer function allows you to monitor the received audio from the hailer horn. The built-in 25W amplifier increases your talk power, making it loud and clear.

Built-in Horn (Automatic & Manual)

Foghorn feature is built-in via the external Hailer horn. Four horn patterns are selectable for the automatic horn function.

ITU Class D DSC (Meets ITU-R M493-13)

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. Up to 100 DSC address IDs can be programmed.

Rear Microphone Version*

With this version, the microphone connector is drawn from the rear panel and a 6.1m (20ft) microphone extension cable is supplied to allow you clean and neat panel installation.
* Ask your dealer for details.
