60 Setup Instructions
Chart speed This adjusts the speed at which the information moves
across the display. Use the < and > arrows of the Page
Control Pad to change the chart speed. Making the bar
longer increases the chart speed. If you move the bar all of
the way to the left, the FishFinder will “freeze” and hold the
current display. (The depth indicator will continue to update.)
If you are done with your setup changes, press the CLEAR button to go
back to the normal display. To select the next menu item, press the
arrow of the Page Control Pad.
Frequency Setting
“Frequency” is a measure of how fast the sound waves from the trans-
ducer change or “vibrate.” This unit uses sound waves with two different
frequencies—50 kHz and 200 kHz. For an explanation on the uses of
these two frequencies, see the section on “Choosing a Frequency.”
From the Chart Speed Menu Item, press the down arrow of the Page
Control Pad. The next menu item will allow you to make the frequency setting.
