IMPORTANT SAFEGUARDS
7
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.
USE
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 is 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.
