Power Sources — The appliance should be connected
to a power supply only of the type described in the
operating instructions or as marked on the ap-
pliance.
Grounding or Polarization — The precautions that
should be taken so that the grounding or polarization
means of an appliance is not defeated.
Power-Cord Protection — Power-supply cords should
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, conve-

overload protection as the original plug.
Cleaning — The appliance should be cleaned only as
recommended by the manufacturer.
Power Lines — An outdoor antenna should be located
away from power lines.
Outdoor Antenna Grounding — If an outside antenna
is connected to the receiver, be sure the antenna
system is grounded so as to provide some protec-
tion against voltage surges and built up static
charges. Section 810 of the National Electrical Code,
ANSI/NFPA No. 70-1984, provides information with
respect to proper grounding of the mast and suppor-

apart.
Mount antenna discharge unit as close as possible to
where lead-in enters house.
Use jumper wire not smatier than No. 6 AWG (13.3 mm7?}
