IMPORTANT SAFETY PRECAUTIONS (Continued)
■ If an outside antenna is connected to the television equipment, 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 Electrical
Code 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.
■ Lightning – For added protection for this television equipment during a lightning
storm, or when it is left unattended and unused for a long period of time, unplug
it from the wall outlet and disconnect the antenna. This will prevent damage to
the equipment 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,
extreme care should be taken to keep from touching such power lines or circuits
as contact with them might be fatal.
■ To prevent fire, never place any type of candle or flames on the top or near the
TV set.
■ To prevent fire or shock hazard, do not expose this product to dripping or
splashing. No objects filled with liquids, such as vases, should be placed on the
product.
■ To prevent fire or shock hazard, do not place the AC cord under the TV set or
other heavy items.
■ Do not display a still picture for a long time, as this could cause an afterimage to remain.
■ Install the product on the place where the AC cord can be unplugged easily from the AC outlet, or from the AC
INPUT terminal on the rear of the product.
