where access can only be gainedby servicepersonnel throughthe useof a special tool, lock and key,
or other means of security, and is controlled by the authority responsible for the location.
Warning When installing the unit, the ground connection must always be made first and
disconnected last.
Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably
installed ground conductor.Contact the appropriate electrical inspection authority or an electrician
if you are uncertain that suitable grounding is available.
Warning A radiation hazard may exist within a specific radius around the center point of the
antenna. The table below associates antenna gain (in dB) with a minimum acceptable distance.
Determine the gain of the antenna and use Table 6 to locate the minimum acceptable distance from
the center point of the antenna. (Transmitter Power = 33 dBi.)
