Low Battery Alarm
Low Battery Alarm sounds when the input
battery voltage is equal to or less than the menu setting. The battery alarm will
only sound for the battery that is connected to the Chartplotter. The Low
Battery Alarm should be set to warn you when the battery voltage drops below
the safety margin that you have determined. For instance, if you are running a
trolling motor (battery operated), you would want to set the Low Battery Alarm
to sound before the battery voltage drops too low for it to be used to start your
main, gasoline-powered engine.

58 degrees Fahrenheit, and the water temperature falls from 60 degrees to
