Replacement parts When replacement parts are required, make sure that the service technician uses replacement parts specified by the manufacturer that have the same characteristics as the original part. Unauthorized substitutions may result in fire, electric shock, personal injury, or other hazards. Safety check After completing any service or repair to this device, ask the service technician to perform routine safety checks to determine that your TV is in correct operating condition. Power source Operate your TV only from the type of power source indicated on the marking label. If you are not sure of the type of power supplied to your home, consult an electrician or your local power company. Cautions Damage requiring service Unplug this TV from the power 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 TV. • If your TV has been exposed to rain or water. • If your TV 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 will often require extensive work by a qualified technician to restore your TV to its normal operation. • If your TV has been dropped or damaged in any way. • When your TV exhibits a distinct change in performance. Outdoor antenna grounding If an outside antenna or cable system is connected to your TV, 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 the antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. 1 2 3 4 5 7 6 1 Antenna lead-in wire 2 Grounding clamp 3 Antenna discharge unit 4 Grounding conductors 5 Ground clamps 6 Power service grounding electrode system 7 Electric service equipment Note to CATV system installer Article 820 of the National Electrical Code, ANSI/NFPA No. 40 provides guidance for correct grounding. Specifically, it states that the cable ground must be connected to the grounding system of the building as close to the point of cable entry as practical. Condensation Moisture will form on the TV if the TV is brought from cool surroundings into a warm room or if the temperature of the room rises suddenly. When this happens, the TV's performance may be impaired. To prevent this, let the TV stand in its new surroundings for about an hour before switching it on, or make sure that the room temperature rises gradually. Condensation may also form during the summer if the TV is exposed to the breeze from an air conditioner. In such cases, change the location of the TV. Mobile telephone warning To avoid interference with your TV picture and sound, operating problems, or even damage, keep your cordless and cellular telephones away from the TV. www.insigniaproducts.com 3
