. This is the safety zone personnel must stay out of while the radar is transmitting. 10-inch Antenna: 12 feet safe distance. 12-inch Antenna: 14 feet safe distance. 14-inch Antenna: 16 feet safe distance. Crucial Rule:
: Ensure the system is running the latest software (e.g., Version 2.60.1 adds "Auto Mode" for GTN Xi systems).
Before unboxing the hardware, installers must reference the manual to verify that the aircraft’s electrical system and environmental envelope match the strict requirements of the unit. : 14 or 28 Vdc dual compatibility Max Input Current : 2.5 A at 28 Vdc maximum load
