Grounding or Polarization
This set may be equipped with a polarized alternating current line plug (a plug having one
blade wider than 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 you electrician to replace your obsolete outlet.
Do not defeat the safety purpose of the polarized plug.
Antennas
Outdoor Antenna Grounding
If an outdoor antenna is installed, follow the precautions below. An outdoor antenna
system should not be located in the vicinity of overhead power lines or other electric light or
power circuits, or where it can come in contact with such power lines or circuits.
WHEN INSTALLING AN OUTDOOR ANTENNA SYSTEM, EXTREME CARE SHOULD
BE TAKEN TO KEEP FROM CONTACTING SUCH POWER LINES OR CIRCUITS AS
CONTACT WITH THEM IS ALMOST INVARIABLY FATAL.
Be sure the antenna system is grounded so as to provide some protection against voltage
surges and built-up static charges. Section 810 of the National Electrical Code (NEC) in USA
and Section 54 of the Canadian Electrical Code in Canada 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.

Refer to section 54-300 of Canadian Electrical Code for Antenna Grounding.
