Entering a Flight ID Number
When configured for FLT ID PWR-UP ENTRY at installation, the flight crew must enter
the Flight ID before the GTX 330 will operate. After the flight crew enters the correct Flight
ID, the aircraft identification that is transmitted in response to ATC radar interrogations is
properly correlated with the associated call sign for voice communication with the aircraft.
If the FLT ID PWR-UP ENTRY is required but does not appear at power up, contact a
Garmin authorized service center for GTX 330 configuration.
No space is needed when entering Flight ID characters. When a Flight ID contains a
space, the GTX 330 automatically removes the spaces upon completion of Flight ID entry.
At system power-up the FLT ID may
appear with no number (as shown) or with the
last FLT ID entered. The cursor covers the
entire FLT ID field.
If the Flight ID appearing at turn-on is
correct, press the CRSR key to move the cursor
to the OK? field. Press CRSR again to accept
the FLT ID. The transponder then begins
normal operation.
When no FLT ID appears or the FLT
ID must be changed, press the number keys
corresponding to the alphanumeric character
entry. For example, to enter the letter R press
the 5 key four times.
Each time an alphanumeric character is entered, press the CRSR key to move the cursor
to the next blank field.
Pressing the CLR key moves the cursor back to the previous
character
.
After the complete FLT ID is entered, press the CRSR key to move the cursor to the OK? field.
Press CRSR again to accept the FLT ID.
When FLT ID entry is complete the transponder begins normal operation.
If an error is made while entering a FLT ID, press the
CLR
key to back up to any point,
including highlighting the OK? field. If an incorrect FLT ID is discovered after the unit begins
operation, turn the GTX 330 off. Then turn it back on and reenter the correct FLT ID.
