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, 8.5V - 13.5V, Default = Off)
Temp Alarm
Temp Alarm sounds when the water temperature
detected by the Matrix 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 Alarm will sound. Similarly, if the water
temperature rises from 56 degrees to 58 degrees, the Temp Alarm will also sound.
To change the Temp Alarm setting:
1. Highlight Temp Alarm on the Alarms main menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Temp Alarm
setting. (Off, 32-120 [Fahrenheit], 0-50 [Celsius], Default = Off)
Alarm Tone
Alarm Tone selects the pitch of the alarm sound. A brief
tone will be produced as you adjust the Alarm Tone so that you can select the tone
that you can hear best.
To change the Alarm Tone setting:
1. Highlight Alarm Tone on the Alarms main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Alarm Tone
setting. (High, Medium, Low, Default = Medium)

Depth Alarm sounds when the depth becomes equal to
or less than the menu setting.
To change the Depth Alarm setting:

2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Depth Alarm
setting. (OFF, 1 to 100 feet, or 0.5 to 30 meters [International Models Only],
Default = OFF)
Fish ID Alarm
Fish ID Alarm sounds when the Fishing System detects
fish that correspond to the alarm setting. Fish ID Alarm
will only sound if Fish ID+™ is on.
To change the Fish ID Alarm setting:

2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Fish ID
Alarm setting. (Off, All, Large/Medium, Large, Default = Off)

Fish ID alarm will sound when a large-sized fish is detected.
