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

4.3 inch Wide Viewing Angle Color TFT Display

If in an emergency situation, press the large
independent Distress button to send an
automated digital Distress signal. The digital
distress signal with GPS coordinates calls forhelp from other ships or coast stations.

The 4.3 inch color TFT display provides an almost 180 degree
very wide viewing angle and displays high resolution charactersand function icons. You can clearly see the display informationfrom various viewing angles. So the radio can be installed
without choosing the installation place. The night mode display
ensures good readability in low light conditions.

Built-in DSC Watch-Keeping Receiverwith the Multiple Task Mode
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 witha 10-character ID name. When you receive a DSC call, while
you are in process with another DSC call, the IC-M803 can hold
both DSC procedures to switch between the DSC calls with theMultiple Task Mode function.

Intuitive User Interface
A combination of the large main dial and software keys at thebottom of the display, provides simple operation and easy
access to often used functions. You can smoothly
enter channel numbers, MMSI numbers,
vessel names with the alpha-numeric
keypad. In addition, one of software key
functions can be assigned to the microphone’s
programmable button for quick access.

The GPS receiver which includes GPS, GLONASS and SBAS
function, is integrated into the IC-M803. Your position data,course, speed and UTC data can bereceived with a simple connection
to the supplied GPS antenna. The
position data can be output from theNMEA 0183 port for use with other
GPS Information screendevices.

Color TFT Display
Two Minutes Instant Replay Memory
The Instant Replay function automatically saves thereceived audio. You can replay the received audio, andnot miss any incoming calls.

Advanced RF Direct Sampling System
The latest digital signal processing system is employed
to the IC-M803. The system totally improves receiversensitivity, and audio clarity over conventional radiosystems.

Ready forHF E-mail Operation
The IC-M803 can be set tomemorize your HF e-mail accessfrequency, mode and bandwidth
setting into the e-mail channels.
Up to 160 e-mail frequency channels, and connection terminals
for a PC and e-mail modem areavailable.
