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 Fishfinder. 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.
To change the Low Battery Alarm setting: 1. Press the LEFT or RIGHT Cursor keys to change the Low Battery Alarm setting. Alarm sounds when the water temperature detected by the Fishfinder reaches the Temp. Alarm setting, which is either set in degrees Fahrenheit or Celsius [International Models only].
For example, if the Temp. Alarm is set to 58 degrees Fahrenheit, and the water temperature falls from 60 degrees to 58 degrees, the Temp. Similarly, if the water temperature rises from 56 degrees to 58 degrees, the Temp. (Off, 33-120 [Fahrenheit], 0-50 [Celsius], Default = Off)
