3-5 Setup > Alarms
Press MENU one or more times until the Setup
menu is displayed, then select Alarms:
Trigger settings can be defined to suit the boat
and individual preferences as follows:
Alarms can be set (enabled) to automatically detect
certain conditions, such as the water being too shal-
low. Alarms that are enabled are shown as black
icons in the Alarm status box on the sonar displays.
When an enabled alarm is triggered, the beeper
sounds, an alarm message is displayed and the
alarm status icon is shown in red.
Press ENT or ESC to acknowledge the alarm,
stop the beeper and close the alarm window. This
does not disable the alarm.
Alarms automatically re-enable
The Too shallow, Too Deep and Low bat-
tery alarms automatically re-enable when the
value moves outside the alarm trigger setting.
The Temperature alarm automatically re-
enables when the temperature is more than
0.45°F (0.25°C) above or below the alarm trig-
ger setting.
The Temperature rate alarm automatically
re-enables when the rate of temperature change
falls below the trigger setting by more than 0.2°F
(0.1°C) per minute.
Flashing light and/or external

If a secondary alarm indicator is required, a flashing
light and/or external beeper can be installed. These
