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 (NEC) in
USA and Section 54 of the Canadian Electrical Code in
Canada 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.
Antenna Grounding According to the NEC
Refer to section 54-300 of Canadian Electrical Code for
Antenna Grounding.

Lightning
For added protection for this television receiver 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. This will prevent damage to
the receiver due to lightning and power-line surges.

❑
If liquid has been spilled into the
set.
❑
If the set has been exposed to rain
or water.
❑
If the set has been subject to
excessive shock by being dropped,
or the cabinet has been damaged.
❑
If the set does not operate normally
when following the operating
instructions. Adjust only those
controls that are specified in the
operating instructions. Improper
adjustment of other controls may
result in damage and will often
require extensive work by a
qualified technician to restore the set to normal
operation.
❑
When the set exhibits a distinct change in
performance, it indicates a need for service.
Replacement Parts
When replacement parts are required, be sure the service
technician certifies in writing that he has used
replacement parts specified by the manufacturer that have
the same characteristics as the original parts.
Unauthorized substitutions may result in fire, electric
shock or other hazards.
Safety Check
Upon completion of any service or repairs
to the set, ask the service technician to
perform routine safety checks (as specified
by the manufacturer) to determine that the
set is in safe operating condition, and to so
certify. When the set reaches the end of its
useful life, ask a qualified service
technician to dispose of the set.
