be routed
so
that they are not likely to be walked
on or
pinched
by items placed
upon or against
them, paying
particular
attention
to cords
at plugs, convenience
receptacles,
and the
point where they exit from the appliance.

uct receiver
during
a lightning
storm,
or
when it is left unattended
and unused
for
long periods
of time, unplug
it from the
wall outlet
and disconnect
the antenna
or
cable system.

discharge
unit, size of grounding
conductors,
location
of antenna
