we would enter an offset of +5 feet. Then in this example, the digital depth
would report a depth of 20 feet (from the surface) and the graphic image
scale range would shift from 0 to 20' to 5 to 25'.
Calibrate Water Speed
: Allows calibrating the value of Water Speed coming from the transducer.
The calibration value, in the range between -10% to +10%, will be applied to the water
speed from the transducer.
Calibrate Water Temp
: Allows the calibration on the Water Temperature sensor. Using the readings from a
precise temperature measuring device, insert a positive/negative offset to display the
correct temperature.
Calibrate Aux Temp
: Allows the calibration of the Aux Temperature sensor. Using the readings from a precise
temperature measuring device, insert here a positive/negative offset to display right
value on FF screens.
Set Default
: Restores the factory settings.

ALARMS
The Alarms menu allows you to define alarm settings for Shallow Alarm, Depth Alarm and

depth value above and below your actual anchoring depth. The alarm will sound when the
depth becomes shallower or deeper than the settings.
Figure 4.8 - Alarms sub-menu
Shallow Water
: Triggers an alarm when depth becomes shallower than the value set.
Depth Water
: Triggers an alarm when depth becomes deeper than the value set.
Fish
: The options for Fish Alarm set the size of the fishes that, if detected by the unit, switches an
alarm to sound. These options are: Off, Small, Medium, Big and Huge. The alarm sounds if
the set size (or bigger) is detected.
Temperature Upper
: Triggers an alarm when the transducer reports a temperature above the value set.
Temperature Lower
: Triggers an alarm when the transducer reports a temperature below the value set.
Temperature Rate
: Triggers an alarm when the transducer reports a temperature variation rate above the value set.
