MENU FUNCTIONS

The Zoom range is shown on the left side of the screen and full range information is shown on the

right side of the display. Zoom can either operate

automatically, in which the Zoom range is constantly adjusted to show the bottom, or manually, in which

the user controls the location of the Zoom range.

Automatic Zoom is especially helpful when looking for structure or bottom detail. The Automatic Zoom keeps the bottom in view even in quickly changing terrain, but is most useful in flatter areas without considerable depth variation. Manual Zoom pro- vides detailed information of any area from the surface to the bottom. In man- ual Zoom, the Zoom range does not move as the terrain changes.

When the range is shown in the menu, the upper number represents the top of the current Zoom range. The lower number represents the bottom of the Zoom range. Use the UP and DOWN ARROW buttons to move this range. The upper number can never be less than 0 (the surface of the water), and the lower num- ber can never be greater than the active depth range. The difference between the two numbers (the Zoom range) is preset and determined by the active depth range.

Once manual Zoom is selected, the display appears the same as in Auto Zoom, but the zoom range does not change automatically.

To disable Zoom, press the MENU button until the Zoom menu is on-screen. Use the UP ARROW to highlight Off, and let the

menu time out.

When the unit is powered off, the Zoom menu returns to Zoom Off.
