Dedicated buttons for channel 16 allow instant access to the emergency channel and are located both on the front of the radio and on the four-button fist microphone.
Class D DSC approval
The integrated emergency button enables automated DSC emergency calls. This feature also allows direct calls to other DSC-equipped vessels from a Simrad multifunction display, including direct calls to AIS targets (compatible display and AIS receiver required).
Three-channel monitoring function
Monitor the current channel, emergency channel 16 and another user-configured priority channels at all times.
All international channels

My channel mode
Save your favourite channels for quick and easy access. A long press of the channel rotary switch takes you to My Channel mode, where you can use the rotary switch to select between your favourites.
Multiple search mode
Monitor all available channels or just your favourites. In both modes, priority can be given to emergency call channels so that you do not miss emergency calls and other important safety messages.
