7. Do not block any of the ventilation openings. Install in accordance with manufacture’s 
instructions.

8. Do not install near any heat sources such as a radiator, heat register, stove or other 
apparatus (including amplifiers) that produce heat.

9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has 
two blades with one wider than the other. A grounding type plug has two blades with a third 
grounding plug. The wide blade or thirds prong is provided for your safety. If the provided plug
