equal to or less than the menu setting.
To change the Depth Alarm setting:
1. Highlight Depth Alarm on the Alarms main menu.

setting. (OFF, 1 to 100 feet, or 0.5 to 30 meters [International models only],

FISH ID ALARM

Fish ID Alarm sounds when the 900 Series™
detects fish that correspond to the alarm setting. Fish ID Alarm will only sound if Fish

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.

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

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 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
