POLARIZED PLUGS
To reduce the risk of electrick shock, this equipment has a polarized plug (one blade is wider
than the other).
This plug will fit in a polarized outlet only one way.
If the plug does not fit fully in the outlet, reverse the plug.
If it still does not fit, contact a qualified electrician to install the proper outlet.
Do not change the plug in any way.
