Simply highlight “Reset Water Distance” and press the ENT key. The menus automatically erase and the water distance display is reset to 0.00.

Sonar Simulator

This unit has a built-in simulator that lets you use it as if you are on the water. All features and functions of the unit are useable. A message ap- pears occasionally that alerts you to the fact that the simulator is on.

To use this, select “Sonar Simu- lator” from the “Sonar Setup” menu. The screen at right ap- pears.

Turn the simulator on by highlight- ing “Simulator On” and pressing the ENT key. The simulator im- mediately begins operation.

If you have a MMC installed, you

can select previously saved charts to show instead of the standard one. Select the chart from the “Charts Used” menu. The unit will use the se- lected chart.

When you are finished with the settings on this screen, press the EXIT key to erase the menus.

SYSTEM SETUP

Many of the unit’s basic features can be changed from this menu. Press the MENU key twice, then select “System Setup”. The screen at right appears.

This menu (shown at the top of the next page) sets the speed and distance (statute or nautical miles, meters), depth (feet, fath-

oms, or meters), temperature (degrees Fahrenheit or Celsius), and head- ing (true or magnetic) units.
