Manual
INFORMATION TO THE USER
NOTE : This  equipment  has  been  tested  and  found  to  comply  with  the  limits  for  a  Class  A  digital  device,
pursuant to Part 15 of the FCC Rules.  These limits are designed to provide reasonable protection
against  harmful  interference  when  the  equipment  is  operated  in  a  commercial  environment.  This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance  with  the  instruction  manual,  may  cause  harmful  interference  to  radio  communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.
TO THE OWNER
As the owner of a new Multi-media Projector, you are probably eager to try out your new projector. Before you do, we suggest
that you spend a little time reading this manual to familiarize yourself with the operating procedures, so that you will receive
maximum satisfaction from the many features included in your new projector.
This owner’s manual will acquaint you with your projector’s features. Reading it will help us too. Through the years, we have
found  that  many  service  requests  were  not  caused  by  problems  with  our  projectors.  They  were  caused  by  problems  that
could have been prevented, if the owner had followed the instructions in the manual.
You  can  often  correct  operating  problems  yourself.  If  your  projector  fails  to  work  properly,  see  “TROUBLESHOOTING”
section on pages 49 ~ 50 and try the solutions marked for each problem.

All  the  safety  and  operating  instructions  should  be  read
before the product is operated.
Read all of the instructions given here and retain them for
later  use.  Unplug  this  projector  from  AC  power  supply
before cleaning. Do not use liquid or aerosol cleaners. Use
a damp cloth for cleaning.
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
manufacturer.
Do  not  expose  this  unit  to  rain  or  use  near  water...  for
example, in a wet basement, near a swimming pool, etc...
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
material, and the bottom opening should not be blocked by
placing  the  projector  on  a  bed,  sofa,  rug,  or  other  similar
surface.  This  projector  should  never  be  placed  near  or
over a radiator or heat register.
This projector should not be placed in a built-in installation
such as a bookcase unless proper ventilation is provided.
This  projector  should  be  operated  only  from  the  type  of
power source indicated on the marking label. If you are not
sure of the type of power supplied, consult your authorized
dealer or local power company.
Do  not  overload  wall  outlets  and  extension  cords  as  this
can result in fire or electric shock. Do not allow anything to
rest on the power cord.  Do not locate this projector where
the cord may be damaged by persons walking on it.
Never push objects of any kind into this projector through
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 projector.
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.
Unplug  this  projector  from  wall  outlet  and  refer  servicing  to
qualified service personnel under the following conditions:
a. When the power cord or plug is damaged or frayed.
b. If liquid has been spilled into the projector.
c. If the projector has been exposed to rain or water.
d. If the projector does not operate normally by following the
operating instructions. Adjust only those controls that are
covered  by  the  operating  instructions  as  improper
adjustment  of  other  controls  may  result  in  damage  and
will often require extensive work by a qualified technician
to restore the projector to normal operation.
e. If the projector has been dropped or the cabinet has been
damaged.
f. When  the  projector  exhibits  a  distinct  change  in
performance-this indicates a need for service.
When  replacement  parts  are  required,  be  sure  the  service
technician  has  used  replacement  parts  specified  by  the
manufacturer  that  have  the  same  characteristics  as  the
original  part.  Unauthorized  substitutions  may  result  in  fire,
electric shock, or injury to persons.
Upon completion of any service or repairs to this projector,
ask the service technician to perform routine safety checks
to determine that the projector is in safe operating condition.
This  projector  is  equipped  with  a
grounding type AC line plug.  Should
you be unable to insert the plug into
the  outlet,  contact  your  electrician.
Do not defeat the safety purpose of
this grounding type plug.
GROUND
Follow  all  warnings  and  instructions  marked  on  the
projectors.
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 powerline surges.
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.
If the projector is to be built into a compartment or similarly
enclosed, the minimum distances must be maintained.
Do not cover the ventilation slot on the projector.
Heat build-up can reduce the service life of your projector,
and can also be dangerous.
