ANTENNAS
Outdoor Antenna Grounding—If an
outdoorantenna or cable system is
installed, follow these precautions:
An outdoor antenna system should not
be located in the vicinity of overhead
power lines or other electric light or
power circuits, or where it can come in
contact with such power lines or circuits.
WHEN INSTALLING AN OUTDOOR
ANTENNA SYSTEM, EXTREME CARE
SHOULD BE TAKEN TO KEEP FROM
CONTACTING SUCH POWER LINES
OR CIRCUITS AS CONTACT WITH
THEM IS ALMOST INVARIABLY
FATAL.
Be sure that the antenna system is
grounded so as to provide some
protection against voltage surges and
built-up static charges. Section 810 of
the National Electric Code(NEC)
provides information with respect to
proper 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.
MAINTENANCE
1. Use a damp cloth to clean the plastic
cabinet. A mild soap will help to
remove grease or oil. Never use
polish, solvents, abrasives or strong
detergents since these can damage
the finish.
2. Your phone should be situated away
from heat sources such as radiators,
heaters, stoves or any other
appliance that produces heat.
