or the third prong is provided for your safety. If the
provided plug does not fi t into your outlet, consult
an electrician for replacement of the obsolete outlet.
If this product connects to coaxial cable wiring, be sure the
cable system is grounded (earthed). Grounding provides some
protection against voltage surges and built-up static charges.
Prevent Power Cord Damage
Protect the power cord from being walked on or pinched,
particularly at plugs, convenience receptacles, and the point
where the cord exits from the apparatus.
