Adjusting the Range Control

The Fishfinder automatically adjusts the display range. Alternatively, the RANGE key lets you select the maximum depth displayed on the scrolling bottom and A-Scope displays. You can also set the shift value to move the image window up or down within the current range.

If you select automatic range adjustment, the Fishfinder selects the shallowest range that still keeps the bottom in the lower half of the display window. When auto-range is selected, shift is disabled (the value is ignored).

To adjust the range and shift values:

1.On the Pathfinder Panel, click RANGE. This sets adjustment to manual and the range buttons are displayed.

2.Click RANGE key to adjust the range as follows: click the up arrow to select a shallower range, click the down arrow to select a deeper range.

3.To adjust the shift, press the appropriate SHIFT soft button: click the UP button to select a shallower shift, click the DOWN button to select a deeper shift. The image window is shifted by the selected amount.

4.Click ENTER, CLEAR, or BACK to return to the top-level Functionbar menu.
