12、anufacturer. 10.2. 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. CAUTION: Read all of these instructions. Save these instructions for later use. Follow all Warnings and Instruct

13、ions marked on the audio equipment. 1. Read Instructions- All the safety and operating instructions should be read before the product is operated. 2. Retain Instructions- The safety and operating instructions should be retained for future reference. 3. Heed Warnings- All warnings on the product and

14、in the operating instructions should be adhered to. 4. Follow Instructions- All operating and use instructions should be followed. IMPORTANT SAFETY INSTRUCTIONS 4 PROTECTION AND LOCATION OF YOUR SET 11.Do not use this television set near water . for example, near a bathtub, washbowl, kitchen sink, o

15、r laundry tub, in a wet basement, or near a swimming pool, etc. Never expose the set to rain or water. If the set has been exposed to rain or water, unplug the set from the wall outlet and refer servicing to qualified service personnel. 12. Choose a place where light (artificial or sunlight) does no

16、t shine directly on the screen. 13. Avoid dusty places, since piling up of dust inside TV chassis may cause failure of the set when high humidity persists. 14. The set has slots, or openings in the cabinet for ventilation purposes, to provide reliable operation of the receiver, to protect it from ov

17、erheating. These openings must not be blocked or covered. Never cover the slots or openings with cloth or other material. Never block the bottom ventilation slots of the set by placing it on a bed, sofa, rug, etc. Never place the set near or over a radiator or heat register. Never place the set in e

18、nclosure, unless proper ventilation is provided. PROTECTION AND LOCATION OF YOUR SET 15.1. If an outside antenna is connected to the television set, be sure the antenna system is grounded so as to provide some protection against voltage surges and built up static charges, Section 810 of the National

19、 Electrical Code, NFPA No. 70-1975, 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 electrode, and require

20、ments for the grounding electrode. 15.2. Note to CATV system installer : (Only for the television set with CATV reception) This reminder is provided to call the CATV system attention to Article 820-40 of the NEC that provides guidelines for proper grounding and, in particular, specifies that the cab

21、le ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical. 16.An outside antenna system should not be located in the vicinity of overhead power lines or other electric lights or power circuits, or where it can fall into such power lines o

22、r circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal. 17.For added protection for this television set during a lightning storm, or when it is left unattended and unused for long peri

23、ods of time, unplug it from the wall outlet and disconnect the antenna. This will prevent damage due to lightning and power-line surges.
