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.

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).

Multiple search mode
