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

TO THE OWNER
As the owner of a new Multimedia Projector, you are probably eager to try out your new projector.  Before you do,
we suggest that your 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 44 ~ 45 and try the solution marked for each problem.
