Do not allow anything to rest on or roll over the
power cord, and do not place the set where the
power cord is subject to wear or abuse.
Antennas
Outdoor Antenna Grounding
If an outdoor antenna 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 (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.

Service
Damage Requiring Service
Unplug the set 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 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.
Servicing
Do not attempt to service the set yourself since
opening the cabinet may expose you to dangerous
voltage or other hazards. Refer all servicing to
qualified service personnel.
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, improper disposal could
result in a picture tube implosion. Ask a qualified
service technician to dispose of the set.
