All functions of the IC-M605 (including DSC and distress operation) can be remotely controlled with up to three controllers, RC-M600 COMMAND HEAD™ and/or HM-195 series COMMANDMIC™, with an intercom function available among the main radio and controllers. The system allows for maximum operating flexibility anywhere on your boat.

Wide Viewing Angle 4.3-inch Color TFT LCD

First in its class, the color LCD provides nearly a 180 degree viewing angle. The 4.3-inch wide display has high resolution characters and function icons. The night mode screen provides the optimal viewing brightness for comfortable operation in the dark.

Integrated AIS* Receiver

With an integrated AIS receiver, the IC-M605 can show real-time AIS vessel traffic information on the display. The AIS combo screen enables you to monitor the AIS plotter during basic operation. You can directly call a selected AIS target from the AIS screen using an individual DSC call.

Intuitive User Interface

A combination of the directional keypad and soft keys provides simple operation. Most used functions are assigned to soft keys (at the bottom of the display) for quick one push function access. The large ten-key pad enables you to smoothly enter channel numbers, MMSI numbers with ID names and so on.

Class Leading Receiver Performance

A weak signal adjacent to a strong signal can be clearly received by the IC-M605. Its commercial grade receiver performance (selectivity and IMD: more than 80 dB) provides reliable communication at all times.

Active Noise Canceling

The Active Noise Canceling digitally removes background noise from both transmit and receive audio and provides clear communication in a noisy maritime environment.

Last Call Voice Recording

The last call voice recording function automatically saves up to two minutes of an incoming call. Don’t miss any incoming messages.

Private Conversation

With an optional voice scrambler unit, UT-112, the IC-M605 provides 32 tone secure conversation. This function is useful when you want to share private information with consort ships.

Provides Clear, Loud Audio

The IC-M605’s internal speaker enhances intelligibility of received calls. The waterproof, paper speaker-cone provides superior sound quality with a wide frequency range and a flat frequency response for powerful, yet clear audio.

30 W Two-Way Hailer and Automatic Foghorn

When connected to the optional horn speaker, SP-37, you can talk with crews on the deck or shore from the radio’s microphone and can hear any reply via the horn speaker. Also available the RX hailer function and four patterns of automatic foghorn.

NMEA 2000™, NMEA 0183/-HS Connectivity

Using NMEA 2000™ connectivity, the radio can exchange GNSS, AIS reports, DSC call information data, radio frequency and PGN list data on the network. NMEA 0183/-HS GNSS position data Private Conversation can also be converted to NMEA 2000™ data for other equipment.
