wall outlet before cleaning. Do not use liquid cleaners or
aerosol cleaners. Use a damp cloth for cleaning.

11A
An appliance and cart combi-
nation should be moved with care.
Quick stops, excessive force, and
uneven surfaces may cause the ap-
pliance and cart combination to over-
turn.
12 Outdoor Antenna Grounding
— If an outside
antenna or cable system is connected to the video prod-
uct, 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 infor-
mation 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 ground-
ing 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 out-
side 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.
