WARNING

This product is equipped with either a three-prong (grounding
pin) safety plug or a two-prong (polarized) safety plug. To
properly ground this product, follow these safety guidelines:

• For a 3-prong plug (one prong on this plug is a protective

grounding pin), insert the plug into a grounded mains, 3-
prong outlet. Note: This plug fits only one way. If you are
unable to insert this plug fully into the outlet, contact your
electrician to replace your obsolete outlet.

• For a 2-prong plug (a polarized plug with one wide blade

and one narrow blade), insert the plug into a polarized
mains, 2-prong outlet in which one socket is wider than the
other. Note: If you are unable to insert this plug fully into the
outlet, try reversing the plug. If the plug still fails to fit,
contact an electrician to replace your obsolete outlet.

 WARNING:

Avoid electric shock and fire hazard! Do not overload
mains AC outlets and extension cords. For products that
require battery power or other power sources to operate
them, refer to the operating instructions for those products.

WARNING:

To avoid electric shock and fire hazard, match the plug
and outlet connections carefully, then fully insert. If the
plug and outlet do not match, or you cannot fully insert the
plug, contact an electrician to update your power outlets.

Do not overload electrical outlets, extension cords, or integral
convenience receptacles as this can result in a risk of fire or
electric shock. For products that require battery power or
other sources to operate, refer to the operating instructions
for that product.
