MF/HF MARINE TRANSCEIVER

Class E DSC MF/HF SSB Radio withDistress Button for Emergencies

4.3 inch Wide Viewing Angle Colour TFT Display

The IC-M804 meets ITU-R M.493-15 and ETSIEN 300 338-4 Class E DSC regulations. In anemergency, by pressing the large independent
Distress button, a digital Distress signal is sentwith GNSS coordinates and calls for help toDistress button with aspring-loaded coverother ships or coast stations.

A high-resolution colour LCD provides an almost 180 degree
very wide viewing angle and displays characters and function
icons clearly. The night mode display ensures good readability inthe dark for further convenience.

Built-in DSC Watch-Keeping Receiver
The dedicated DSC watch-keeping receiver continuously scans
the six distress channels in rotation. A total of 100 MMSI numbers (75 Individual and 25 Group) for DSC calls can be storedwith a 10-character ID name.

Two Minutes Instant Replay Memory
The Instant Replay function automatically records the last 2 minutes of received audio. You can playback the received audio thatyou could not hear clearly, and will not miss any incoming call.

Intuitive User Interface

Meets Strict Environmental Requirements

The combination of the directional keypad and soft keys provides
simple operation. The most common functions are assigned tosoft keys (at the bottom of the display) for quick push functionaccess. The large ten-key pad enables you to smoothly enterchannel numbers, MMSI numbers with ID names and so on.

The IC-M804 has passed rigorous environmental testing andquality assurance processes. It is designed to provide reliable
operation and corrosion resistant durability under harsh maritimeenvironments. The controller has IPX7 protection (1 m depth ofwater for 30 minutes).

h Colour TFT Display
Integrated GNSS Receiver
The GNSS receiver which includes
GPS, GLONASS and SBAS function, is integrated into the IC-M804.
Your position data, course, speed
and UTC data can be received witha simple connection to the supplied
GNSS antenna with a 5 m cable.
Supplied GNSS antenna

NMEA 2000™, NMEA 0183/-HS Connectivity
Using NMEA 2000™ connectivity, the IC-M804 can exchange
GNSS, DSC call information, radio information and PGN list dataon the network. NMEA 0183/-HS GNSS position data can also
be converted to NMEA 2000™ data for other equipment.
