unit says that you are moving faster than you really are, you

 

can adjust the Speed Cal figure to a smaller number. If the

 

unit says that you are moving slower than your actual

 

speed, use a larger number for Speed Cal. The setting can

 

range between 75 and 125. Use the < and > controls to

 

change the value. For more information, see the section on

 

“Calibrating the Sensors.”

Temp Cal

This unit can display the water temperature. You may want

 

to fine-tune the signal from the transducer to get an

 

accurate display. The displayed number indicates an offset

 

added to the measured temperature. (This offset will be

 

measured in °F or °C, depending on the setting used for

 

Temp Units.)

For example, if the temperature reading on

 

the FishFinder Page tends to read 2°F too high, you can

 

correct for this by setting Temp Cal to -2.0°. The setting

 

can range between -9.9° and +9.9°. Use the < and >

 

controls to change the value.

Depth Digits

This item sets the size of the digits used to show the bottom

 

depth on all of the display pages except for the Window and

 

Digital Pages. The “STD.” (standard) setting will display

 

digits which are 7 mm tall, and the “LARGE” setting will

 

display digits which are 15 mm tall. Use the < and >

 

controls to change the setting.

Shallow Alarm

 

 

 

 

 

You can set an alarm to trigger whenever the boat moves

 

into water which is shallower than a limit you set. Use the

 

< and V controls to move to the line for Shallow Alarm

 

and use the > control on the Page Control Pad to turn this

 

item on. Once you do this, the display will ask which depth

 

you want to use as a limit. Use the < and > controls to set

 

the limit you want. When the shallow alarm is set, the letter

 

“S” will appear in the upper left-hand corner of the normal

 

displays. If you move into shallow water and trigger the

 

alarm, the letter “S” will begin to flash, and the buzzer will

 

sound. Press the

 

button to silence the buzzer. The

 

CLEAR

 

letter “S” will continue to flash until you move into

 

deeper water.
