NOTE: Requires antenna tuner AT141_65 and OPC1465 Cable for a complete HF radio.
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 calls.
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).
