gets in your eyes or touches your skin, consult with
your doctor after rinsing for at least 15 minutes or

Outdoor antenna grounding
If an outside antenna or cable system is connected to
your TV, make sure that the antenna or cable system is
grounded to provide some protection against voltage
surges and built-up static charges. Article 810 of the
National Electrical Code, ANSI/NFPA No. 70, provides
information with respect to correct grounding of the
mast and supporting structure, grounding of the
lead-in wire to an antenna discharge unit, size of
grounding conductors, location of the
antenna-discharge unit, connection to grounding
electrodes, and requirements for the grounding

Article 820 of the National Electrical Code, ANSI/NFPA
No. 40 provides guidance for correct grounding.

temperature of the room rises suddenly. When this
happens, the TV's performance may be impaired. To
prevent this, let the TV stand in its new surroundings
for about an hour before switching it on, or make sure
that the room temperature rises gradually.
Condensation may also form during the summer if
the TV is exposed to the breeze from an air
conditioner. In such cases, change the location of the
