USING THE 200DXUSING THE 200DX
CONTROL FUNCTIONS
Light. LIGHT controls the unit's display backlight. With the unit powered on, press
LIGHT once to turn the backlight on “high." Press LIGHT a second time to turn the
backlight on “low,” and a third time turns the backlight off. The backlight is very effective
for low-light and nighttime operation. When the backlight is on the 200DX will consume
more power than with the backlight off. This is important when using the 200DX in a
portable configuration powered by a separate battery, or when powering the unit from a
trolling motor battery.
When powering the unit from a battery such as in portable applications, you can prolong
the battery life by using the backlight at a minimum.
The three lower buttons, MENU, UP ARROW, and DOWN ARROW work together to
control the 200DX menu-controlled user functions.
Menu. MENU displays a menu on-screen for adjustment. In
normal operation, pressing MENU repeatedly cycles through all
available menu headings. When a menu heading displays the full
menu appears after a short pause. A menu remains on-screen for
several seconds and can be adjusted by using the ARROW keys. If no adjustment is
made in the allotted time, the menu disappears. If you want the menu to remain on-
screen longer, press and hold MENU the menu will remain on-screen indefinitely.
Once you release the menu button, the screen will time out. Once a menu times out, it
is still considered the active menu. Press MENU to bring up the last menu used.
Arrow Keys. The UP ARROW and DOWN ARROW make adjustments to menu
functions. On the left side of every menu there are UP ARROW and DOWN ARROW
symbols. The symbols indicate which ARROW button has a function in a particular
situation. Either one or both ARROW buttons can be used to adjust the menu function.
A hollow ARROW symbol means the corresponding ARROW button has no function.
Pressing that button will result in no adjustment and the error audible will be heard.
