Shallow Water
: Sounds when the water depth is shallower than
the specified depth.
Water Temperature
: Sounds when the water temperature
varies more than ± 2 °F (± 1.1 °C). Alarm settings are saved
when the device is turned off.
NOTE:
You must connect the device to a temperature-
capable transducer to use this alarm.
Sonar Numbers Settings
You can adjust which numbers are displayed on the full screen
page, the split zoom page, and the split frequency page. You
can also adjust the size of the numbers.

Calibration
Setting the Keel Offset
You can enter a keel offset to compensate for the surface
reading for the depth of a keel, making it possible to measure
depth from the bottom of the keel instead of from the transducer
location.
1
Select an option, based on the location of the transducer:
• If the transducer is installed at the water line
À
, measure
the distance from the transducer to the keel of the boat.
Enter this value in step 3 as a positive number.
• If the transducer is installed at the bottom of the keel
Á
,
measure the distance from the transducer to the water
line. Enter this value in step 3 as a negative number.

Use the arrow keys to enter the keel offset measured in step
1.
Setting the Water Temperature Offset
You can set the temperature offset to compensate for the
temperature reading from a temperature-capable sensor.
1
Measure the water temperature using the temperature-
capable transducer that is connected to the device.
2
Measure the water temperature using a different
thermometer or temperature sensor that is known to be
accurate.
3
Subtract the water temperature measured in step 1 from the
water temperature measured in step 2.
This is the temperature offset. Enter this value in step 6 as a
positive number if the sensor connected to the device
measures the water temperature as being colder than it
actually is. Enter this value in step 6 as a negative number if
the sensor connected to the device measures the water
temperature as being warmer than it actually is.
