INSTALLATION AND OPERATION MANUAL
FOR SEA TEL MODEL
9797B-76 C/KU-BAND TX/RX ANTENNA
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.
