12  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 No. 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 example below: 
13  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 or approaching such power lines 
or circuits as contact with them might be fatal.  Installing an outdoor antenna can be hazardous and should be 
left to a professional antenna installer. 
14  Cleaning -- Unplug this video product from the wall outlet before cleaning.  Do not use liquid cleaners or 
aerosol cleaners.  Use a damp cloth for cleaning. 
15  Object and Liquid Entry -- Never push objects of any kind into this video product 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 video product. 
16  Lightning -- For added protection for this video product during a lightning storm, or when it its left 
unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or 
cable-system.  This will prevent damage to the video product due to lightning and power-line surges. 
17  Servicing -- Do not attempt to service this video product yourself as opening or removing covers may 
expose you to dangerous voltage or other hazards.  Refer all servicing to qualified service personnel. 
18  Conditions Requiring Service -- Unplug this video product from the wall outlet and refer servicing to 
qualified service personnel under the following conditions. 
a. When the power-supply cord or plug is damaged 
b. If liquid has been spilled or objects have fallen into the video product.
