Large Color Display
Users will like the large 4.3" wide viewing angle color TFT display. Clearly see the high resolution display icons on the LCD screen from numerous positions with the nearly 180 degree wide viewing angle, which provides various installation placement possibilities. The night mode display offers readability in low-light conditions.

Intuitive User Interface
Smoothly operate and sail with the M803’s large main dial and keys to access functions such as accessing MMSI numbers, vessel numbers, and channels with the full alpha-numeric keypad. Assign one of the software key functions to the microphone’s programmable button for quick access. Additionally the head unit offers programmable keys for customizable access.

Emergency Distress Button
The M803’s big and easily identifiable emergency distress button is encased in a spring loaded cover. Once pressed a digital distress signal is sent with GPS coordinates and calls for help to other ships or coast stations. The GPS receiver offers GPS, GLONASS, SBAS, position data, speed and UTC data when using the supplied GPS antenna. Position data may be output from the NMEA 0183 port for use with other devices.

Dedicated DSC Scanning
The dedicated DSC watch-keeping receiver continuously scans the six distress channels in rotation. If you are in process with a DSC call and receive another call, the M803 can switch between calls with the Multiple Task Mode function. 100 MMSI numbers (75 individual/25 group) for DSC calls can be stored with a 10-character name.

Two Minute Memory Instant Replay Memory
The Instant Replay Function allows users to replay up to two minutes of previous conversations or calls. The function constantly loops and records over older audio.
