received, the historical information scrolls left across the display.
Upper and Lower Depth Range numbers indicate the distance from
the surface of the water to a depth range sufficient to show the bottom.
Sensitivity: Press the UP or DOWN Arrow keys to adjust the Sensitivity.

The Zoom Level, or magnification, will be displayed on the screen.
