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.
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.
Service
Damage Requiring Service
Unplug the set from the wall outlet and refer servicing to qualified service
personnel under the following conditions:

damage and will often require extensive work by a
qualified technician to restore the set to normal operation.
s
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 an LCD panel implosion. Ask a
qualified service technician to dispose of the set.
Carrying the TV
When carrying the TV, hold it as shown in the diagram on
the right. Do not hold only the rear cover. As the rear cover
comes off easily, doing so may cause you to drop the TV,
resulting in damage to the TV or injury.
Optional Accessories
Be sure to follow the operating instructions supplied with your wall mount
unit when installing the TV using a wall mount unit. If not, the TV may fall
and cause serious injury.
Oils
Do not install this TV in restaurants where oil vapors occur. Dust absorbing
oil may enter into the TV and damage it.
Ventilation holes
Do not insert anything in the ventilation holes. If metal or
something flammable enters, it may result in fire or
electric shock.
AC power cord
Unplug the AC power cord when moving the TV.
Do not move the TV with the AC power cord plugged in. It may damage
the AC power cord and result in fire or electric shock.
Protruding location
Do not install the TV in protruding locations. If you install the TV in the
following locations, injury may result.
s
Do not install the TV in a location where the TV protrudes, such as
pillars.
s
Do not install the TV in a location that may cause facial injury.
Broken pieces
Do not throw anything at the TV.
The screen glass may explode by the impact and cause serious injury.
