The Softkeys; The Function Keys - Leica MX400 Operating Instructions Manual

Operator's Manual
The receiver uses a Transflective LCD display screen. It provides
optimum viewing in virtually all lighting conditions. To change the
display contrast or backlight condition, select the CFG function key
and scroll down to the Lighting menu choice. Refer to the CFG
section of the manual for a complete description of menu options.
The function key ( ) just above the Power On/Off key allows you
to quickly change between day-time and night-time screen settings.
Information displayed on the screen is normally divided into
windows, similar to what you might see on a normal computer.
Each screen has a page number in the upper left hand corner
. These page numbers are there to help you quickly find the
information you need, and to help us guide you on the rare occasion
that you might request our assistance.
With the exception of a portion of the PLOT and MOB screens
which use two softkeys to change the view scale, all of the screens
require that you press the E (Edit Mode) function key before you
are allowed to change data on the screen. You can use the cursor
key (the big key with the arrows pointing in four directions) to
move between edit fields or menu choices on most screens when in
the edit mode. When you are not in the edit mode, you can use the
cursor to scroll between screens (i.e. NAV1, NAV2, NAV3, ...) or
to move up and down on screens (like the menu bar in the CFG
screen).

The Softkeys:

The five softkeys under the display are so named because their
purpose changes from one menu or screen to the next. With the
exception of a portion of the PLOT screens and the MOB screens,
all of the screens require that you press the E (Edit Mode) function
key before the softkeys can be accessed. Don't forget to press the E
function key when you are finished editing a screen.

The Function Keys:

The Function Keys are the keys to the right of the display. There are
18 function keys in all. Eleven of the function keys access various
screen and editing displays. Three of these keys are used for editing
or moving within the screens. One key is used to mark your present
position, another is used strictly for Man Over Board alarms. One
switches between two display lighting options, and finally there is
