•Some equipment has a three-wire grounding plug. This type of plug has a third grounding pin. As a safety feature, the plug only fits into an isolated ground outlet. If you cannot insert the plug completely into the outlet, contact your electrician to replace the outlet.

Some equipment has a polarized line plug. This type of plug has one blade wider than the other. As a safety feature, this plug fits into the power outlet one way only. If you cannot insert the plug completely into the outlet, try reversing the plug. If the plug continues to not fit, contact your electrician to replace the plug.

•Do not place objects on the power cord. Do not locate the product where persons can walk on the plug.

•Do not overload wall outlets and extension cords, as fire or electrical shock can result.
