OPERATION IN WEATHER MODE
WARNING: Begin transmitting only when it is safe to do so. When transmitting while the aircraft is on the
ground, no personnel or objects should be within 9.16 feet of the antenna.
CAUTION: In Standby mode, the antenna is parked at the center line. It is always a good idea to put the
radar in Standby mode before taxiing the aircraft to prevent the antenna from bouncing on the bottom stop
and possibly causing damage to the radar assembly.
