than the specified value.
Deep Water : Sets an alarm to sound when the depth is greater
than the specified value.
Water Temp. : Sets an alarm to sound when the transducer
reports a temperature that is 2°F (1.1°C) above or below the
specified temperature.
Contour : Sets an alarm to sound when the transducer detects a
suspended target within the specified depth from the surface
of the water and from the bottom.
Fish : Sets an alarm to sound when the device detects a
suspended target.

Select Settings > Alarms > Weather .
2
Turn on alarms for specific weather events.
Setting the Fuel Alarm
Before you can set a fuel level alarm, a compatible fuel flow

Temp. Offset : Allows you to set an offset value to compensate
for the water temperature reading from a NMEA 0183 water-
temperature sensor or a temperature-capable transducer
( Setting the Water Temperature Offset , page 45 ).
Calibrate Water Speed : Calibrates the speed-sensing
transducer or sensor ( Calibrating a Water Speed Device ,
page 45 ).
