Chapter 4: Setup Instructions

There are two groups of setup menus. When you press the Menu

button, the unit presents four Soft Keys. See Fig. 4-1. If you make a

change, press the Enter button to save the change and return to the

normal display. To return without making a change, press Clear.

Most of the displays on the Fishfinder show a record of the signals the

unit has received. The new information appears at the right edge of the

display. The older information moves toward the left of the display. (If

the Sidelooker screen is displayed, the new information appears at the

top and moves toward the bottom.) The chart speed adjustment sets

the speed at which the display moves. (Notice that the scrolling speed of

the display is not related to the speed of the boat over the bottom. The

speed of the display is controlled only by the chart speed setting.)
