BASIC OPERATION
The KFD 840 utilizes two rotary control knobs and five function keys
to control the unit.
Rotary Control Knobs
The knob on the right of the display controls the heading bug (HDG)
and the knob on the left of the display controls the course pointer
(CRS). Both knobs are used to select and control additional
functions. These functions are selected by pressing the knob.
The operation of both the right and left knobs are identical. Pressing
the knob once (and releasing it in less than 2 seconds) displays the
menu for the additional functions which can be controlled by that
knob. Pressing the knob when the menu is displayed advances the
menu selection up. The selection is highlighted and the active
selection is displayed above the knob.
