selecting the altitude bug. The bug will move to the closes 100
ft mark of the current altitude. Then rotating the right hand
knob SELECT ALT will allow the altitude to be selected.
Each step of the rotary encoder moves the bug 500ft. while
depressing the knob provides 100ft. steps. The altitude bug will
never move out of view but will remain ether at the top of the
altimeter to indicate selected altitude is above current altitude or
the bottom to indicate selected altitude is below current altitude.
The selected altitude can always be seen above the ALT on the
display.

have been setup correctly, the EFIS screen will display NO GPS
FIX until the GPS unit has acquired satellites. Then the display
