Important
Safeguards
Before using your LCD projection TV, please read these
instructions completely, and keep this manual for future
reference.
Carefully observe and comply with all warnings, cautions
and instructions placed on the set or described in the
operating instructions or service manual.
WARNING
To guard against injury, the following basic safety
precautions should be observed in the installation, use
and servicing of the set.
Use
Power Sources
This set should be operated only from
the type of power source indicated on
the serial/model plate.
If you are not sure of the type of
electrical power supplied to your home, consult your
dealer or local power company. For those sets designed to
operate from battery power, refer to the operating
instructions.
Grounding or Polarization
This set is equipped with a polarized AC power cord plug
(a plug having one blade wider than the other), or with a
three-wire grounding type plug (a plug having a third pin
for grounding). Follow the instructions below:
For the set with a polarized AC power cord
plug
This plug will fit into the power outlet
only one way. This is a safety feature. If
you are unable to insert the plug fully
into the outlet, try reversing the plug.
If the plug still fails to fit, contact your electrician to have
a suitable outlet installed. Do not defeat the safety
purpose of the polarized plug by forcing it in.
For the set with a three-wire grounding type
AC plug
This plug will only fit into a grounding-
type power outlet. This is a safety
feature. If you are unable to insert the
plug into the outlet, contact your
electrician to have a suitable outlet
installed. Do not defeat the safety purpose of the
grounding plug.
Overloading
Do not overload wall outlets, extension
cords or convenience receptacles
beyond their capacity, since this can
result in fire or electric shock.
Always turn the set off when it is not
being used. When the set is left
unattended and unused for long
periods of time, unplug it from the
wall outlet as a precaution against the
possibility of an internal malfunction that could create a
fire hazard.
If a snapping or popping sound from a TV
set is continuous or frequent while the TV
is operating, unplug the TV and consult
your dealer or service technician. It is
normal for some TV sets to make
occasional snapping or popping sounds,
particularly when being turned on or off.
Object and Liquid Entry
Never push objects of any kind into the
set through the cabinet slots as they may
touch dangerous voltage points or short
out parts that could result in a fire or
electric shock. Never spill liquid of any
kind on the set.
Attachments
Do not use attachments not
recommended by the manufacturer, as
they may cause hazards.
Cleaning
Clean the rear cover area of the LCD projection TV
regularly. Dusts in rear cover area may cause the
problem with cooling system of the LCD projection
TV set.
Clean the cabinet of the LCD
projection TV with a dry soft cloth.
To remove dust from the screen,
wipe it gently with a soft cloth.
Stubborn stains may be removed
with a cloth slightly dampened with solution of mild
soap and warm water. Never use strong solvents
such as thinner or benzine for cleaning.
If the picture becomes dark after using the LCD
projection TV for a long period of time, it may be
necessary to clean the inside of the LCD projection
TV. Consult qualified service personnel.
Unplug the AC power cord when cleaning this unit.
If not, it may result in electric shock.
