with a cart, stand, tripod, bracket, or table recommended by the manufacturer, or sold with the video product. Any 
mounting of the product should follow the manufacturer's instructions, and should use a mounting accessory 
recommended by the manufacturer. 
11A  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. 
 
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: 
EXAMPLE OF ANTENNA GROUNDING 
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.

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.

b. If liquid has been spilled, or objects have fallen into the video product. 
c. If the video product has been exposed to rain or water. 
d. If the video product 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
