Garmin 328 - Manual (Page 9)

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 328 off. Then turn it back on again and reenter the correct
FLT ID.
