Using the 200DX

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.
