• Ventilation-Slots and openings in the cabinet and the back or bottom are provided for ventilation, to ensure reliable operation of your home theater system, and to protect it from overheating. Do not block openings. Do not place your home theater system on a bed, sofa, rug, or other similar surface. Your home theater system should never be placed near or over a radiator or heat register. Do not place your home theater system in a built-in installation such as a bookcase or rack unless correct ventilation is provided or the manufacturer's instructions have been adhered to. • Power sources-Use only the type of power source indicated on the marking label. If you are not sure of the type of power supply to your home, consult your home theater system dealer or local power company. • Grounding or polarization-Your home theater system is equipped with a polarized alternating-current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug. • Power-cord protection-Route power-supply cords so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from your home theater system. • Outdoor antenna grounding-If an outside antenna or cable system is connected to your home theater system, make sure that the antenna or cable system is grounded to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/ NFPA No. 70, provides information with respect to correct grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode.

This will prevent damage to your home theater system due to lightning and power-line surges. • Power lines-An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, do not touch power lines or circuits because contact with them might be fatal. • Overloading-Do not overload wall outlets and extension cords because this can result in a risk of fire or electric shock. • Object and liquid entry-Never push objects of any kind into your home theater system through openings because they may touch dangerous voltage points or short out parts that could result in a fire or electric shock. Never spill liquid of any kind on your home theater system. • Servicing-Do not attempt to service your home theater system yourself because opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel. • Damage requiring service-Unplug your home theater system from the wall outlet and refer servicing to qualified service personnel under the following conditions: • When the power supply cord or plug is damaged or frayed. • If liquid has been spilled, or objects have fallen into your home theater system. • If your home theater system has been exposed to rain or water. • If your home theater system does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions, because incorrect adjustment of other controls may result in damage and often requires extensive work by a qualified technician to restore your receiver to its normal operation. • If your home theater system has been dropped or damaged in any way. • When your home theater system exhibits a distinct change in performance, this indicates a need for service. 4 www.insignia-products.com
