Important Safeguards
For your protection, 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:
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 cabinet of the 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 projection TV
for a long period of time, it may be necessary to clean the
inside of the projection TV. Consult qualified service
personnel.
