If you turn on your unit before attaching a transducer, it may enter 

a demo mode. The words "demo mode" flash on the bottom of the 

screen and a sonar chart plays much like the simulator. Unlike the 

simulator, the demo mode is for demonstration only, and will 

automatically stop as soon as you turn on the unit with a trans-

ducer attached. The simulator will continue to function normally. 

If you are running multiple units on a boat, there are times when you 

may want to turn off the sonar. This command turns off the sonar and 

stops the chart from scrolling. Sonar restarts automatically each time 

you turn on your unit. 
To Stop Chart from running: 
1. Press

To turn on sonar and start the chart scrolling again, repeat the above step. 

 

The markings extending downward from the zero line on the chart are 

called "surface clutter." The clutter is caused by wave action, boat 

wakes, temperature inversion and more. 
The surface clarity control reduces or eliminates surface clutter signals. 

It  does  this  by  changing  the  sensitivity of the receiver, decreasing it 

near the surface and gradually increasing it as the depth increases.
