Pedestal Power Supply. Observe proper safety precautions when working inside the Antenna
Breaker Box or Power Supply.
WARNING: RF Radiation Hazard - This stabilized antenna system is designed to be used with
transmit/receive equipment manufactured by others. Refer to the documentation supplied by the
manufacturer which will describe potential hazards, including exposure to RF radiation, associated
with the improper use of the transmit/receive equipment. Note that the transmit/receive
equipment will operate independently of the stabilized antenna system.
The ultimate responsibility for safety rests with the facility operator and the individuals
who work on the system.
WARNING: RF Radiation Hazard - Prior to working on the stabilized antenna system, the power
to the transmit/receive equipment must be locked out and tagged. Turning OFF power to the
Antenna Control Unit does NOT turn Transmit power output OFF.

who work on the system.
WARNING:
RF Radiation Hazard - When the transmit/receive system is in operation, no one
should be allowed anywhere within the radiated beam being emitted from the reflector.
