Do not spill food or liquids on your system components, and never operate the product in a wet

Position system cables and power cables carefully; route system cables and the power cable and plug
so that they cannot be stepped on or tripped over. Be sure that nothing rests on your system
components' cables or power cable.
Do not modify power cables or plugs. Consult a licensed electrician or your power company for site
modifications. Always follow your local/national wiring rules.
