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.

To change the Low Battery Alarm setting:

1.Highlight Low Battery Alarm on the Alarms main menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Low Battery Alarm setting. (Off, 8.5V - 13.5V, Default = Off)

Aux. Temp. Alarm

(with optional-purchase temp. probe or Temp/Speed only)

Aux. Temp. Alarm sounds when the water temperature from the Paddlewheel/Temperature Probe detected by the Chartplotter reaches the Aux. Temp. Alarm setting, which is either set in degrees Fahrenheit or Celsius [International Models only]. For example, if the Aux. Temp. Alarm is set to 58 degrees Fahrenheit, and the water temperature falls from 60 degrees to 58 degrees, the Aux. Temp. Alarm will sound. Similarly, if the water temperature rises from 56 degrees to 58 degrees, the Aux. Temp. Alarm will also sound.

To change the Aux. Temp. Alarm setting:

1.Highlight Aux. Temp. Alarm on the Alarms main menu.

2.Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Aux. Temp. Alarm setting. (Off, 33-120 [Fahrenheit], 0-50 [Celsius], Default = Off)
