     Do not cover or block these vents and openings since insufficient ventilation can cause overheating and/or shorten the life 
of the product. Do not place the product on a sofa, rug or other similar surface, since they can block ventilation openings. 
Do not place the product in an enclosed place such as a bookcase or rack, unless proper ventilation is provided or the

parts specified by the manufacturer, or those with the same characteristics and performance as the original parts. Use of 
unauthorized parts can result in fire, electric shock and/or other danger.
