Function Selector Knob
The Function Selector Knob on
the right side of the KT 73 enables
you to choose from the following
operating modes:
OFF - The unit is not receiving power.
When the unit is turned to another
mode, it will reply or squitter within
two seconds, according to the
selected mode.
FLT ID (FLIGHT ID) - The Flight ID
should be the aircraft identification

flight plan is available, the registration

been turned to the SBY position the
flight ID will be saved.

shown on the left side of the display
and the ID code is shown on the right.

check the KT 73's integrity, verifying
all aircraft specific configuration data
and make hardware and squitter
