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 Matrix Fishing System. 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)
Off Course Alarm
Off Course Alarm sounds when the boat has moved too far off course
based on the menu setting when navigating. Off Course Alarm allows you to set how far the boat is
allowed to move off course before the Off Course Alarm will sound.
To change the Off Course Alarm setting:
1. Highlight Off Course Alarm on the Alarms main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Off Course Alarm setting.
(Off, 30 to 3000 feet, 10 to 1000 meters [International Models Only], Default = 300 ft, 100 m)
