compartments should be serviced only by a trained service technician.
• If any of the following conditions occur, unplug the product from the electrical outlet and
replace the part or contact your trained service provider:
– The power cable, extension cable, or plug is damaged.
– An object has fallen into the product.
– The product has been exposed to water.
– The product has been dropped or damaged.
– The product does not operate correctly when you follow the operating instructions.
• Use the product only with approved equipment.
• Operate the product only from the type of external power source indicated on the
electrical ratings label. If you are not sure of the type of power source required, consult
your service provider or local power company.
• Handle batteries carefully. Do not disassemble, crush, puncture, short external contacts,
dispose of in fire or water, or expose batteries to temperatures higher than
60 degrees Celsius (140 degrees Fahrenheit). Do not attempt to open or service batteries;
replace batteries only with batteries designated for the product.
