2.2. Controls
The primary means for the pilot to control the EBD are the two knobs and three buttons
at the right-hand side of the display. The knobs control setting IAS and HDG. The right-
hand three buttons control selection of navigation sources for the GPS. There are three
additional buttons to the left of the Hot Keys to control entering and exiting the Menu,
setting the Map Range, and Manual Power Control (PWR).
Five Hot Keys above the Navigation Display toggle various features on and o. The
function of each is indicated by the label on the display below each key.
2.2.1. Top and Bottom Knobs
The Top and Bottom Knobs are designed to provide immediate operation yet minimize
the possibility of an inadvertent operation. This is accomplished by requiring that the rst
action of the knob “wakes up” the knob and changes the label from cyan to magenta.
The rst click when the knob is turned or the rst press on the knob, “wakes up” the knob
function.
Press the knob more than once to cycle through its Menu options in a round-robin
sequence or press and hold the knob to synchronize (SYNC) the function’s value (see
Section 2.2.1.3. SYNC Function). After 10 seconds of inactivity, the knob returns to its
default setting.
