POWER LINES
An outside antenna system should not be located in
the vicinity of overhead power lines or other electric
light or power circuits,
or where it can fall into such power lines
or circuits. When installing an outside antenna
system, extreme care should be taken to keep from
touching such power lines or circuits as contact with
them might be fatal.
POLARIZATION
This video product is equipped with a polarized
alternating current line plug (a plug having one blade
wider than the other.) This plug will fit into the power
outlet only one way.
This is a safety feature. If you are unable
to insert the plug fully into the outlet, try reversing
the
plug. If the plug should still fail to fit, contact your
electrician to replace your obsolete outlet. Do not
defeat the safety purpose of the polarized plug.
OUTDOOR ANTENNA GROUNDING
•
If an outside antenna is connected to the
antenna terminal, be sure the antenna system
is grounded so as to provide some protection
against voltage surges and built-up static
charges.
•

Electrical Code, ANSI/NFPA No. 70-1984,
provides information with respect to proper
grounding of the mast and supporting
structure, grounding of the lead-in wire
to an antenna discharge unit, size of grounding
conductors location of antenna discharge unit,
connection to grounding electrodes, and
requirements for the grounding electrode.
