Touch Done to accept the number. Turn Transition Distance-set how far before a turn in a route that you transition to the next leg. AIS-turn AIS on or off. AIS alerts you to area traffic by providing boat IDs, position, course, and speed for boats that are within range and equipped with a transponder. DSC-turn DSC on or off. AIS Alarm (AIS only)-set an alarm to sound when other AISequipped vessels are within a specified range. This is used for collision avoidance and can be customized. • Range-change the measured radius of the Safe Zone ring to a specified distance from 500 ft. to 2.0 nm (or 150 m to 3 km, or 500 ft. to 2.0 mi.). • Time to (Safe Zone)-sounds an alarm if AIS determines that a target will intersect the Safe Zone within the defined time interval (ranging from 1 to 24 minutes).
