Important safeguards (continued)
ANTENNAS
Outdoor Antenna Grounding – If an outdoor antenna or cable system is
installed, follow the precautions below.
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 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 electrodes, and
requirements for the grounding electrode.

Lightning
For added protection for this unit 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 unit due to lightning and power-line surges.
SERVICE
Damage requiring service
Unplug the unit from the wall outlet and refer
servicing to qualified service personnel under
the following conditions:
– When the power cord or plug is damaged or
frayed.
– If liquid has been spilled or objects have fallen
onto the unit.
– If the unit has been exposed to rain or water.
