Service

Damage Requiring Service

Unplug the unit from the wall outlet and refer servicing to qualified
service personnel under the following conditions:

s

When the power cord or plug is
damaged or frayed.

If liquid has been spilled into the unit.

s

If the unit has been exposed to rain or water.

If the unit has been subject to excessive shock
by being dropped, or the cabinet has been
damaged.

s

If the unit 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 unit to normal operation.

s

When the unit exhibits a distinct change in
performance, it indicates a need for service.

Servicing

Do not attempt to service the unit 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/she
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 unit, ask
the service technician to perform routine safety checks (as
specified by the manufacturer) to determine that the unit is
in safe operating condition, and to so certify. When the
unit reaches the end of its useful life, ask a qualified
service technician to dispose of the unit.

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 National
Electrical Code, ANSI/NFPA 70

Lightning

For added protection for this TV 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.
