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 900 Series™. 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, 9.0V - 13.5V, Default = Off)
TEMP ALARM
Temp Alarm sounds when the water
temperature detected by the 900 Series™ 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° Fahrenheit, and the water temperature falls from 60° to
58°, the Temp Alarm will sound. Similarly, if the water temperature rises from 56° to
58°, the Temp Alarm will also sound.
