NOTE:

If you turn on your unit before attaching a transducer, it may enter a
demo mode. The words "demo mode" in a pop-up box flash in the
middle 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.

Stop Chart

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

Sonar Menu with Stop Chart command selected. The box is unchecked,

indicating that the chart is scrolling across the screen.

Surface Clarity

The markings extending downward from the zero line on the chart are
called "surface clutter." These markings are caused by wave action,
boat wakes, temperature inversion and more.

The surface clarity control reduces or eliminates surface clutter signals
from the display. It does this by changing the sensitivity of the receiver,
decreasing it near the surface and gradually increasing it as the depth
increases.
