Important Safety Precautions
22. Power source---This product is intended to be supplied by a listed power supply indicated on the
marking label. If you are not sure of the type of power supply to your home, consult your product dealer
or local power company. For added protection for this product 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
cable system. This will prevent damage to the product due to lightning and power line surges. When the
unit has to be used with another power supply voltage, the power cable must be changed. Consult your
product dealer. The socket outlet should be installed near the equipment and easily accessible. Use
only the power cord designated by our dealer to ensure safety and EMC. When connecting other
products such as VCRs and personal computers, you should turn off the power of the unit for protection
against electric shock.
23.Panel protection---The PDP panel used in this product is made of glass.
Therefore, it can break when the product is dropped or impacted upon by
other objects. Be careful not to be injured by broken glass pieces in case
the PDP panel breaks.
24.Pixel defect---The PDP panel is a very high technology product, giving you finely detailed pictures.
Occasionally, a few non-active pixels may appear on the screen as a fixed point of blue, green or red.
Please note that this does not affect the performance of your product.

If an outside antenna is connected to the television equipment, 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.
NEC—NATIONAL ELECTRICAL CODE
<
An outside antenna system should not be located in the vicinity of
overhead power lines or other electric light or power circuits, or where it
can collide with such power lines or circuits. When installing an outside
antenna system, extreme care should be taken to keep from touching
such power lines or circuits, as contact with them might be fatal.
