ALARM FUNCTION
The unit has an alarm function to protect your ship from collisions. If other ships, islands or other obstructions.
come into the pre-programmed alarm zone, the function alerts you with an alarm. You can set the desired range
and bearing for an alarm zone. While the alarm function is activated, the power save function turns OFF the LCD
until an alarm is given, to conserve power.
