or less than the menu setting. The battery alarm will only sound for the battery that is connected to the

1100 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.

NOTE: Your unit will detect when your battery voltage is too low or too high, and will display either Input Voltage

Low or Input Voltage High messages if these limits are exceeded. If you turn the Low Battery Alarm on using the

Alarms Main Menu, your unit will use your settings. If you do not turn the Low Battery Alarm on, the unit will

use these limits: 7.5 to 7.9 VDC for the low end, and 21 to 21.2 VDC for the high end.

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)

the water temperature falls from 60 degrees to 58 degrees, the Aux. Temp. Alarm will sound. Similarly, if the
