Depth Alarm

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

To change the Depth Alarm setting:

1.Highlight Depth Alarm on the Alarms main menu.

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+TM is on.

For example, if you've set the Fish ID Alarm to sound for Large fish only, the Fish ID alarm will sound when a large-sized fish is detected.

To change the Fish ID Alarm setting:

1.Highlight Fish ID Alarm on the Alarms main menu.

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)

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 300 Series™ 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 300 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 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, 33-120 [Fahrenheit], 0-50 [Celsius], Default = Off)
