The right hand knob is used to set squawk codes and the Flight ID.

will highlight the first digit on the display, and the digit can be changed
as required. Press the ENT button to advance to the next digit. When
ENT is pressed on the last digit, the new squawk code or Flight ID will
replace the previous value. If the code entry is not completed within 7

end it.
Flight Timer
The Flight Timer records the time for which the transponder has been
powered on and operating in flight mode – either ON or ALT. Press
