RETAIN INSTRUCTIONS � The safety and operating instructions should be retained for future reference. HEED WARNINGS � All warnings on the appliance and in the operating instructions should be adhered to. FOLLOW INSTRUCTIONS � All operating and usage instructions should be followed. CLEANING � Unplug this product from the wall outlet before cleaning. The product should be cleaned only with a polishing cloth or a soft dry cloth. Never clean with furniture wax, benzine, insecticides or other volatile liquids since they may corrode the cabinet. ATTACHMENTS � Do not use attachments not recommended by appliance manufacturer as they may cause hazards. WATER AND MOISTURE � Do not use this appliance near water � for example, near a bathtub, wash bowl, kitchen sink, or laundry tub, in a wet basement, or near a swimming pool, etc. ACCESSORIES � Do not place this appliance on an unstable cart, stand, tripod, bracket, or table. The appliance may fall, causing serious injury to a child or adult, and serious damage to the appliance. Use only with a cart, stand, tripod, bracket, or table recommended by the manufacturer, or sold with the appliance. Any mounting of the appliance should follow the manufacturer's instructions, and should use a mounting accessory recommended by the manufacturer. CART � An appliance and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the appliance and cart combination to overturn. POLARIZATION � This unit's power cord has a polarized plug (one blade is 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 � Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them. Pay particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance. OUTDOOR ANTENNA GROUNDING � If an outside antenna or cable system is connected to the video product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. Section 810 of the National Electrical Code, ANSI/NFPA 70, provides information with respect to proper 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. See Figure A. LIGHTNING � For added protection for the unit during a lightning storm, unplug it from the wall outlet and disconnect the cable system input. This will prevent damage due to lightning and power-line surges. OVERLOADING � Do not overload wall outlets and extension cords as this can result in a risk of fire or electric shock. OBJECT AND LIQUID ENTRY � Never push objects of any kind into this appliance through openings as 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 the appliance. SERVICING � Do not attempt to service this appliance yourself as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to your cable company. REPLACEMENT PARTS � When replacement parts are required, be sure the service technician has used replacement parts specified by the manufacturer or have the same characteristics as the original part. Unauthorized substitutions may result in fire, electric shock or other hazards. SAFETY CHECK � Upon completion of any service or repairs to this appliance, ask the service technician to perform safety checks to determine that the appliance is in proper operating condition. DAMAGE REQUIRING SERVICE � Unplug this appliance from the wall outlet and call your cable company under the following conditions: ÷ When the power-supply cord or plug is damaged. ÷ If liquid has been spilled, or objects have fallen into the appliance. ÷ If the appliance has been exposed to rain or water. ÷ If the appliance does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions. Improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the appliance to its normal operation. ÷ If the appliance has been dropped or the cabinet has been damaged. ÷ When the appliance exhibits a distinct change in performance � this indicates a need for service.
