The IC-M506 features the most Advanced Waterproof housing; IPX8. Designed and tested to survive after being submersed in 1m of water for 60 minutes. The "Last Call" voice recording function automatically saves the last two minutes of incoming calls so you are able to replay previously received calls in case you need to clarify an important incoming call that might have been missed.

The new intuitive Icom common user interface provides fast and intuitive operation to control its multiple functions. A high-definition dot matrix display allows all information such as GPS, DSC, and the radio menu’s to be clearly viewed.

Call for Help with Marine Electronics The IC-M506 also features Icom’s "Active Noise Cancelling" technology. Using its digital signal processor, the built in bi-directional noise cancelling feature improves audio quality both during transmission and receiving. This feature assures you are heard and you can hear when you really need to, such as when weather conditions are poor or if engines are running.

The option of a second station command mic is also available via the COMMAND MIC IV. Most features including AIS and DSC functions can be controlled from the COMMANDMIC IV. It can also be used as an intercom between the two. The Icom M506 provides 25W Two-Way Hailer capability. 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 their reply via the hailer speaker.

Integrated AIS Receiver
With an integrated AIS receiver, the IC-M506 can show AIS vessel traffic information on the display. The AIS target call function allows you to easily set up an individual DSC call. The Plotter, Target list and Danger list can be toggled on the display.

NMEA 2000® and NMEA 0183 Connectivity
With the plug-and-play functionality of NMEA 2000, the IC-M506 can easily connect to a NMEA 2000 network and interconnect with other equipment. Also the NMEA 0183 input/output can be used for external GPS/NAV interface.

Last Call Voice Recording
The last call voice recording function automatically saves the last two minutes of the last incoming call. You can also start recording manually.

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.

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 horn. Foghorn and RX speaker functions are also available.

Optional COMMANDMIC™ HM-195B/SW
The optional COMMANDMIC, HM-195B/SW provides 2nd station capability for using the IC-M506 from a separate cabin or tower. Most functions including DSC and AIS functions can be controlled from the COMMANDMIC and can be used as an intercom between the IC-M506 and the COMMANDMIC.

Large LCD and Intuitive User Interface
The IC-M506 is equipped with 132x96 pixels dot-matrix display which is larger than the IC-M504 (132?64 pixels). Reading GPS, AIS, DSC and radio menus are easier than ever.
