Radar 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 11 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.
When the weather radar system is in the Weather or Ground Map mode, the
system automatically switches to Standby mode on landing.
