4. CLEANING: Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a

5. GROUNDING or POLARIZATION: This product may be equipped with a polarized alternating current line plug (a plug

since it is likely you have an out of sate wall socket. Never force the plug into the socket.
6. OVERLOADING: Do not overload wall outlets or extension cords as this can result in the risk of
fire or electric shock. Overloaded AC outlets, extension cords, frayed power cables, damaged
or cracked wire insulation, and broken plugs are dangerous. They may result in electric shock
or fire hazard. Periodically examine the power cable - if its appearance indicates damage or
deteriorated receptacles have it replaced by your service technician.
7. POWER SOURCES: This product should be operated only from the type of power source indicated on the rear panel label. If
you are not sure of the type of power supply to your home, consult your product dealer or local power company. For products
intend to be operated from battery power, or other sources, refer to the operation instructions.
8. ACCESSORIES: Do not place this product on an unstable surface or support. The product may fall,
causing serious injury to a child or adult as well as serious damage to the product. Any mounting of
the product should follow the manufacture
’s instructions and use a mounting accessory
recommended by the manufacturer. A product and cart combination should be moved with care.
Quick stops, excessive force, and uneven surfaces may cause the product and cart combination to
overturn.
9. OUTDOOR ANTENNA GROUNDING: If an outside antenna or cable system is connected to the
product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and
built-up static charges. The example below is for reference only. Correct grounding should always be installed by an
electrician.
