INSTALLATION AND OPERATION MANUAL
9797A-27 C-BAND TX/RX ANTENNAS
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. Prior to work on the stabilized antenna system, the
power to the transmit/receive system must be locked out and tagged.
When the transmit/receive system is in operation, no one should be allowed
anywhere within the radiated beam being emitted from the reflector.
The ultimate responsibility for safety rests with the facility operator and the
individuals who work on the system.
Look to the Leader. Look to Sea Tel.
