Owner’s Manual
TO THE OWNER
Before operating this projector, read this manual thoroughly and operate the projector properly.  
This  projector  provides  many  convenient  features  and  functions.    Operating  the  projector  properly  enables  you  to
manage those features and maintains it in better condition for a considerable time.
Improper  operation  may  result  in  not  only  shortening  the  product-life,  but  also  malfunctions,  fire  hazard,  or  other
accidents.
If your projector seems to operate improperly, read this manual again, check operations and cable connections and try
the solutions in the “Trouble-shooting” section of the end of this booklet.  If the problem still persists, contact the sales
dealer where you purchased the projector or the service center.
SAFETY PRECAUTIONS
WARNING :  TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO
RAIN OR MOISTURE.
G This projector produces intense light from the projection lens.  Do not stare directly into the lens as possible.  It
could  damage your eyes.  Be especially careful that children do not stare directly into the beam.
G This projector should be set in the way indicated.  If not, it may result in a fire hazard.
G Take appropriate space on the top, sides and rear of the projector
cabinet  for  allowing  air  circulation  and  cooling  the  projector.

For added protection to the projector during a lightning storm,
or  when  it  is  left  unattended  and  unused  for  long  periods  of
time, unplug it from the wall outlet.  This will prevent damage
due to lightning and power line surges.
Do not attempt to service this projector yourself as opening or
removing  covers  may  expose  you  to  dangerous  voltage  or
other  hazards.    Refer  all  servicing  to  qualified  service
personnel.
Do  not  expose  this  unit  to  rain  or  use  near  water...  for
example, in a wet basement, near a swimming pool, etc...
Do  not  use  attachments  not  recommended  by  the
manufacturer as they may cause hazards.
Do not place this projector on an unstable cart, stand, or table.
The  projector  may  fall,  causing  serious  injury  to  a  child  or
adult,  and  serious  damage  to  the  projector.    Use  only  with  a
cart or stand recommended by the manufacturer, or sold with
the  projector.    Wall  or  shelf  mounting  should  follow  the
manufacturer's  instructions,  and  should  use  a  mounting  kit
approved by the manufacturers.
An appliance and cart combination should
be  moved  with  care.    Quick  stops,
excessive  force,  and  uneven  surfaces
may  cause  the  appliance  and  cart
combination to overturn.
Slots and openings in the back and bottom of the cabinet are
provided  for  ventilation,  to  insure  reliable  operation  of  the
equipment and to protect it from overheating.
The  openings  should  never  be  covered  with  cloth  or  other

restore the projector to normal operation.
e. If the projector has been dropped or the cabinet has been
damaged.
