OPERATING INSTRUCTIONS
"For appliances with a polarized plug (one blade wider than the other).
To reduce the risk of electric shock, this plug is intended to 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 modify the plug in any way."
