Distress Button for Emergencies
The IC-M804 meets ITU-R M.493-15 and ETSI EN 300 338-4 Class E DSC regulations. In an emergency, by pressing the large independent Distress button, a digital Distress signal is sent with GNSS coordinates and calls for help to other ships or coast stations.
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 stored with a 10-character ID name.
Intuitive User Interface
The combination of the directional keypad and soft keys provides simple operation. The most common functions are assigned to soft keys (at the bottom of the display) for quick push function access. The large ten-key pad enables you to smoothly enter channel numbers, MMSI numbers with ID names and so on.
4.3 inch Wide Viewing Angle Colour TFT Display
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 in the dark for further convenience.
Two Minutes Instant Replay Memory
The Instant Replay function automatically records the last 2 minutes of received audio. You can playback the received audio that you could not hear clearly, and will not miss any incoming call.
Meets Strict Environmental Requirements
The IC-M804 has passed rigorous environmental testing and quality assurance processes. It is designed to provide reliable operation and corrosion resistant durability under harsh maritime environments. The controller has IPX7 protection (1 m depth of water for 30 minutes).
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 with a simple connection to the supplied GNSS antenna with a 5 m cable.

AT-141 Automatic Antenna Tuner
The AT-141 automatic antenna tuner matches all bands to your antenna. If due to a fault the automatic tuner cannot tune the antenna, the IC-M804 bypasses the tuner and will display an alert on the display.

Ingress Protection (IP) Code
Ingress Protection (IP) ratings define the level of protection provided by enclosures to prevent the ingress of foreign objects (dust) and liquid into the electrical equipment.
International Standard IEC 60529 outlines an international classification system that describes the sealing characteristics of electrical equipment.
The classification system uses the “IP” code, or “Ingress Protection” code, to define the level of seal.
An IP number contains two numbers (i.e. IP67) in most instances which relate to the level of protection provided by an enclosure or housing.
Either number may be shown as “X” (i.e. IPX6 / IP7X) to indicate the “X” part is not tested.
Degrees of Solid Particle Protection – 1st Digit
|IP6x||No ingress of dust; complete protection against contact. (Dust tight)|
|IP5x||Protected from the amount of dust that would interfere with normal operation. (Dust protected)|
Degrees of Liquid Ingress Protection – 2nd Digit
|IPx8||Protected against continuous immersion in water.
Depth and duration specified by model.
|IPx7||Protected against temporary immersion in water for 1 m (3.3 ft) for 30 minutes|
|IPx6||Protected against water projected by powerful jets from any direction.
100 L per minute by a powerful jets (12.5 mm) for 3 minutes.
|IPx5||Protected against water projected by jets from any direction.
12.5 L per minute by a nozzle (6.3 mm) for 3 minutes.
|IPx4||Protected against water splashed against the equipment from any direction|
