finished editing. If after editing you press a function key
and nothing seems to happen, check to make sure you
didn’t accidentally alter your information and press the
EDIT key to end editing. Some edit screens provide an
Escape softkey. If you decide for some reason that you
don’t want to use the changes you have made, pressing
the Escape softkey will restore the original information.
However, once you press the EDIT key, all changes are
accepted and the original data is lost.
The virtual softkeys under the bottom of the display
are so named because their purpose changes from one
menu or screen to the next. All of the screens require
that you press the EDIT (Edit Mode) function key before
the virtual softkeys can be accessed. Then use the LEFT
and RIGHT cursor arrows to highlight the desired virtual
softkey and press the ENT key to choose it. Don’t forget
to press the EDIT function key when you have finished
editing a screen.
The Function Keys:
The Function Keys are the keys to the right of the display.
There are 16 function keys in all. Eleven of the function
keys access various screen and editing displays. Three of
these function keys are used for editing or moving within
the screens. One function key is used to mark your pres-
ent position, and to activate/deactivate Man Over Board
alarms when depresses for a few seconds. One is used as
the power on/off key, and switches between two display
lighting options when depresses for a few seconds.
The ten function keys with alpha abbreviations on them
are described in the ensuing chapters. The five func-
tion keys with symbols and the GOTO key are described
below.
The function keys are also used in the edit mode to enter
alphanumeric information into screen data fields.
