Electric Power
Power Sources - This unit should be operated only from the
type of power source indicated on the marking label. If you are
not sure of the type of power supply to your home, consult your
appliance dealer or local power company
. To operate unit on
battery power , or other sources, refer to the operating instructions.
Grounding or Polarization - This unit is provided 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.
Power-Cord Protection - This unit is provided with an attachment
plug having overload protection.
This is a safety feature. See
operating instructions for replacement or resetting of protective
device. If replacement of the plug is required, be sure the service
technician has used a replacement plug specified by the
manufacturer that has the same overload protection as the
original plug.
Overloading - Do not allow anything to rest on the power cord.
Do not overload wall outlets and extension cords as this can
result in fire or electric shock. Do not locate this unit where the
cord will be abused by persons walking on it.
Outdoor Antenna
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.
Outdoor Antenna Grounding - If an outside antenna or cable
system is connected to the unit, be sure the antenna or cable
system is grounded so as to provide some protection against
voltage surges and built-up static charges. Section 810 of the
National Electrical Code, ANSI/NFPA No.70, provides information
with regard 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. See the figure.
Lightning
For added protection for this unit 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. This will prevent damage to the unit due to lightning and
powerline surges.

shock or other hazards.
