MENU FUNCTIONS
After an adjustment is made, the menu disappears and the new sensitivity setting is in
effect. If additional time is needed to study a menu press and hold the MENU button
and the menu will remain on-screen indefinitely. If you need to make an additional
adjustment, press the UP ARROW or DOWN ARROW button.
Depth Range. The Depth Range function controls the vertical
distance displayed on the graphic area of the display. There are
nine depth ranges available. The top of the range is always 0, or
the surface of the water. Ranges of 0-15’, 0-30’, 0-60’, 0-120’, 0-
180’, 0-240’, 0-360’, 0-480’, and 0-600’ are available. In the metric
version, ranges of 0-5, 0-10, 0-20, 0-40, 0-60, 0-80, 0-110, 0-150, and 0-185 meters are
available. The range that positions the bottom depiction closest to the bottom of the
screen, will best utilize the available display resolution.
The 200DX automatically adjusts the depth range depending on
the depth of the water. The unit tries to maintain the bottom
depiction about 2/3 down the total range (for example, in 20' (6m)
of water the 0-30' (0-10m) range would be selected). This
provides the best display resolution and therefore the best target
separation possible.
The Depth Range can be adjusted manually. Press MENU repeatedly until the Depth
Range menu is visible. Two options are available: Auto and Manual.
The manual setting enables you to adjust the current depth range
setting. The unit no longer adjusts the Depth Range to the most
appropriate range for bottom display. Often, the bottom may not be
visible on-screen. The digital depth readout always determines the
depth of the bottom, even it is not visible on-screen.
