Important Safety Precautions - Sharp LC-15B4U Operation Manual

IMPORTANT SAFETY PRECAUTIONS (Continued)
I 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 elec-
trodes, and requirements for the grounding electrode.
NEC—NATIONAL ELECTRICAL CODE
I Lighting – For added protection for this television equipment
during a lightning storm, or when it is left unattended and
unused for 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.
I 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.
I To prevent fire, never place any type of candle or naked
flames on the top or near the TV set.
I To prevent fire or shock hazard, do not expose this products
to dripping or splashing. No objects filled with liquids, such
as vases, should be placed on the products.
