MENU FUNCTIONS
The Zoom range is shown on the Ieft 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 provides detailed information of any area from the surface to the bottom. In
manual 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 number 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.
