(b) Code restoration on Power-up
On power-up, the displayed code will be the last active code used before power
was removed.

VFR OPERATION:

Momentarily depressing the "VFR" pushbutton will cause the preprogrammed VFR code to
supersede whatever 4096 Code was previously entered.
The 4096 Code will be accepted for interrogation reply sequences.
The 4096 Code will be stored as the last active 4096 Code just as if it were programmed from
the front panel.
(a)

VFR Programming

The VFR code will be programmable pending the following conditions:
(b)

Last Code Reversion

REPLY:
If the unit is replying to a valid Mode S interrogation, the reply nomenclature "R" will be illuminated
twice per second. If the unit is replying to ATCRBS interrogations, the reply nomenclature "R" will
be illuminated once per second.

ALTITUDE DISPLAY:

(a) When in the ALTITUDE mode, when an altitude source is available, and when the
derived altitude is valid, the KT 73 will display the Flight Level altitude in the Altitude
window of the display. The altitude will be displayed in hundreds of feet.
(b) When in the ALTITUDE mode the Flight Level nomenclature, "FL", will be illuminat-
ed.
(c) When in the ALTITUDE mode and an altitude source is unavailable, the altitude
window will display dashes.
(d) When in the ALTITUDE mode and the derived altitude is invalid, the altitude win-
dow will display dashes.

1. The mode select knob indicates Standby mode.
2. The 4096 code to be programmed is displayed.
3. While the "IDT" pushbutton is latched, the "VFR" pushbutton
is depressed.
1. Pressing the "VFR" Pushbutton for 2±0.5 seconds will dis-
play the last non-VFR 4096 code.
2. The non-VFR code will be transmitted 3.5±0.5 seconds after
the code is displayed.
NOTE:
Flight Level is a term to indicate that the altitude is
not true altitude but barometric altitude which is not
corrected for local pressure. For Example, "FL 040"
corresponds to an altitude of 4000 feet, meaning sea
level pressure of 29.92 inches of mercury.
