4. To select between Hex or Tail number, press the CRSR key, then 8 or 9 key to
move to the correct selection.
5. For entering either the address hex code or the US registration number, press the
CRSR key 1 time. (This highlights the address field).
7. Enter the aircraft address using the number keys. Press a key repeatedly to scroll
through the digit/alpha characters for that key.
8. Press the CRSR key to select the next numeric entry field. Enter the next character
as stated in step 7, then move onto the next one, repeating the process until the
complete number is entered.
9. When finished, press the CRSR key to accept the number entry.
10. Using the FUNC and/or START/STOP keys, toggle through the pages to get off of,
then back onto the aircraft address page. Verify that the address is correct.
The unit now contains a Mode S address and may be turned off. To power the unit on in the normal
mode, press only the ON, ALT, or STBY key (without holding the FUNC key) or turn on with the

MODE S FLIGHT ID PAGE
For operation requiring the flight crew to enter an aircraft
identification designator each time the unit is powered up, select
the page identified as FLIGHT ID PWR-UP ENTRY. When
this choice is selected and the crew enters the Flight ID correctly, the flight number call sign for radio
contact with ATC is the same flight identification that the GTX 330 Mode S transponder replies to ATC
radar interrogations.
The screen depicted here shows the FLIGHT ID PWR-UP ENTRY (choice 2) after the CRSR key is
pressed, and the unit is ready to receive the flight identification.
An important factor to consider while configuring the GTX 330 is this:
POWER UP ENTRY requires that a variable Mode S address is entered each time the unit is powered
on. The selections SAME AS TAIL and CONFIG ENTRY are fixed Mode S addresses. The two fixed
selections do not require any transponder interaction from the flight crew, whereas POWER UP ENTRY
always does.
