while projection is in progress.
■Before you move the projector, make sure its power is turned off, the 
plug is disconnected from the outlet, and all cables are disconnected.
■Never try to remove the lamp immediately after use because it will be 
extremely hot. Before removing the lamp, turn off the power and wait at 
least an hour to allow the lamp to cool completely.
■Do not place the source of an open flame, such as a lit candle, on or near 
the projector.
■Do not modify the power cord. Do not place heavy objects on top of the 
power cord or bend, twist, or pull it excessively. Keep the power cord 
away from hot electrical appliances.
■If the lamp breaks, ventilate the room to prevent gases contained in the 
lamp from being inhaled or coming in contact with the eyes or mouth.

General Public License Version 2 at  http://www.gnu.org/licenses/.
GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc., 51 Franklin Street, Fifth 
Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute 
verbatim copies of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share and 
change it.  By contrast, the GNU General Public License is intended to guarantee your 
freedom to share and change free software--to make sure the software is free for all 
its users.  This General Public License applies to most of the Free Software 
Foundations software and to any other program whose authors commit to using it.  
(Some other Free Software Foundation software is covered by the GNU Lesser 
General Public License instead.)  You can apply it to your programs, too. 
						

							
Notices165
When we speak of free software, we are referring to freedom, not price.  Our General 
Public Licenses are designed to make sure that you have the freedom to distribute 
copies of free software (and charge for this service if you wish), that you receive 
source code or can get it if you want it, that you can change the software or use 
pieces of it in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you 
these rights or to ask you to surrender the rights. These restrictions translate to 
certain responsibilities for you if you distribute copies of the software, or if you modify 
it.
For example, if you distribute copies of such a program, whether gratis or for a fee, 
you must give the recipients all the rights that you have.  You must make sure that 
they, too, receive or can get the source code.  And you must show them these terms 
so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you 
this license which gives you legal permission to copy, distribute and/or modify the 
software.
Also, for each authors protection and ours, we want to make certain that everyone 
understands that there is no warranty for this free software.  If the software is 
modified by someone else and passed on, we want its recipients to know that what 
they have is not the original, so that any problems introduced by others will not reflect 
on the original authors reputations.
Finally, any free program is threatened constantly by software patents.  We wish to 
avoid the danger that redistributors of a free program will individually obtain patent 
licenses, in effect making the program proprietary.  To prevent this, we have made it 
clear that any patent must be licensed for everyones free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, 
DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of 
this General Public License.  The Program, below, refers to any such program 
or work, and a work based on the Prog ram means either the Program or any 
derivative work under copyright law: that is to say, a work containing the 
Program or a portion of it, either verbatim or with modifications and/or translated 
into another language.  (Hereinafter, translation is included without limitation in 
the term modification.)  Each licensee is addressed as you.
Activities other than copying, distribution and modification are not covered by 
this License; they are outside its scope.  The act of running the Program is not 
restricted, and the output from the Pr ogram is covered only if its contents 
constitute a work based on the Program (independent of having been made by 
running the Program). Whether that is true depends on what the Program does. 
						

							
166Notices
1. You may copy and distribute verbatim copies of the Programs source code as you receive it, in any medium, provided that you conspicuously and appropriately 
publish on each copy an appropriate copyright notice and disclaimer of warranty; 
keep intact all the notices that refer to this License and to the absence of any 
warranty; and give any other recipients of the Program a copy of this License 
along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at 
your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus  forming a work based on the Program, and copy and distribute such 
modifications or work under the terms of Section 1 above, provided that you 
also meet all of these conditions:
a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in  part contains or is derived from the Program or any part thereof, to be 
licensed as a whole at no charge to all third parties under the terms of this 
License.
c) If the modified program normally reads commands interactively when run,  you must cause it, when started running for such interactive use in the 
most ordinary way, to print or display an announcement including an 
appropriate copyright notice and a notice that there is no warranty (or else, 
saying that you provide a warranty) and that users may redistribute the 
program under these conditions, and telling the user how to view a copy of 
this License.  (Exception: if the Program itself is interactive but does not 
normally print such an announcement, your work based on the Program is 
not required to print an announcement.)
These requirements apply to the modified work as a whole.  If identifiable 
sections of that work are not derived from the Program, and can be reasonably 
considered independent and separate works in themselves, then this License, 
and its terms, do not apply to those sections when you distribute them as 
separate works.  But when you distribute the same sections as part of a whole 
which is a work based on the Program, the distribution of the whole must be on 
the terms of this License, whose permissions for other licensees extend to the 
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to 
work written entirely by you; rather, the intent is to exercise the right to control 
the distribution of derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on the Program with 
the Program (or with a work based on the Program) on a volume of a storage or 
distribution medium does not bring the other work under the scope of this 
License.
3. You may copy and distribute the Program (or a work based on it, under Section  2) in object code or executable form under the terms of Sections 1 and 2 above 
provided that you also do one of the following: 
						

							
Notices167
a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above 
on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any  third party, for a charge no more than your cost of physically performing 
source distribution, a complete machine-readable copy of the 
corresponding source code, to be distributed under the terms of Sections 1 
and 2 above on a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute  corresponding source code.  (This alternative is allowed only for 
noncommercial distribution and only if you received the program in object 
code or executable form with such an offer, in accord with Subsection b 
above.)
The source code for a work means the preferred form of the work for making 
modifications to it.  For an executable work, complete source code means all the 
source code for all modules it contains, plus any associated interface definition 
files, plus the scripts used to control compilation and installation of the 
executable.  However, as a special exception, the source code distributed need 
not include anything that is normally distributed (in either source or binary form) 
with the major components (compiler, kernel, and so on) of the operating 
system on which the executable runs, unless that component itself 
accompanies the executable.
If distribution of executable or object code is made by offering access to copy 
from a designated place, then offering equivalent access to copy the source 
code from the same place counts as distribution of the source code, even 
though third parties are not compelled to copy the source along with the object 
code.
4. You may not copy, modify, sublicense, or distribute the Program except as  expressly provided under this License.  Any attempt otherwise to copy, modify, 
sublicense or distribute the Program is void, and will automatically terminate 
your rights under this License. However, parties who have received copies, or 
rights, from you under this License will not have their licenses terminated so 
long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not signed it.   However, nothing else grants you permission to modify or distribute the 
Program or its derivative works.  These actions are prohibited by law if you do 
not accept this License.  Therefore, by modifying or distributing the Program (or 
any work based on the Program), you indicate your acceptance of this License to 
do so, and all its terms and conditions for copying, distributing or modifying the 
Program or works based on it.
6. Each time you redistribute the Program (or any work based on the Program), the  recipient automatically receives a license from the original licensor to copy, 
distribute or modify the Program subject to these terms and conditions.  You 
may not impose any further restrictions on the recipients exercise of the rights 
granted herein. You are not responsible for enforcing compliance by third parties 
to this License. 
						

							
168Notices
7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on 
you (whether by court order, agreement or otherwise) that contradict the 
conditions of this License, they do not excuse you from the conditions of this 
License.  If you cannot distribute so as to satisfy simultaneously your obligations 
under this License and any other pertinent obligations, then as a consequence 
you may not distribute the Program at all.  For example, if a patent license would 
not permit royalty-free redistribution of the Program by all those who receive 
copies directly or indirectly through you, then the only way you could satisfy 
both it and this License would be to refrain entirely from distribution of the 
Program.
If any portion of this section is held invalid or unenforceable under any particular 
circumstance, the balance of the section is intended to apply and the section as 
a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or other 
property right claims or to contest validity of any such claims; this section has 
the sole purpose of protecting the integrity of the free software distribution 
system, which is implemented by public license practices.  Many people have 
made generous contributions to the wide range of software distributed through 
that system in reliance on consistent application of that system; it is up to the 
author/donor to decide if he or she is willing to distribute software through any 
other system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be a 
consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in certain countries  either by patents or by copyrighted interfaces, the original copyright holder who 
places the Program under this License may add an explicit geographical 
distribution limitation excluding those countries, so that distribution is permitted 
only in or among countries not thus excluded.  In such case, this License 
incorporates the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of the  General Public License from time to time.  Such new versions will be similar in 
spirit to the present version, but may differ in detail to address new problems or 
concerns.
Each version is given a distinguishing version number.  If the Program specifies 
a version number of this License which applies to it and any later version, you 
have the option of following the terms and conditions either of that version or of 
any later version published by the Free Software Foundation.  If the Program 
does not specify a version number of this License, you may choose any version 
ever published by the Free Software Foundation. 
						

							
Notices169
10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission.  
For software which is copyrighted by the Free Software Foundation, write to the 
Free Software Foundation; we sometimes make exceptions for this.  Our 
decision will be guided by the two goals of preserving the free status of all 
derivatives of our free software and of promoting the sharing and reuse of 
software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO  WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE 
COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM 
AS IS WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR 
IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 
MERCHANTABILITY AND FITNESS FO R A PARTICULAR PURPOSE.  THE 
ENTIRE RISK AS TO THE QUALITY  AND PERFORMANCE OF THE PROGRAM 
IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME 
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN  WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO 
MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED 
ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, 
SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF 
THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT 
LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR 
LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE 
PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH 
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 
SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to 
the public, the best way to achieve this is to make it free software which everyone 
can redistribute and change under these terms.
To do so, attach the following notices to the program.  It is safest to attach them to 
the start of each source file to most effectively convey the exclusion of warranty; and 
each file should have at least the copyright line and a pointer to where the full notice 
is found. 
Copyright (C)

Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this when it starts in an 
interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes 
with ABSOLUTELY NO WARRANTY; for details type `show w. This is free 
software, and you are welcome to redistribute it under certain conditions; type 
`show c for details.
The hypothetical commands `show w and `show c should show the appropriate parts 
of the General Public License.  Of course, the commands you use may be called 
something other than `show w and `show c; they could even be mouse-clicks or 
menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your school, if 
any, to sign a copyright disclaimer for the program, if necessary.  Here is a sample; 
alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program 
`Gnomovision (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into 
proprietary programs.  If your program is a subroutine library, you may consider it 
more useful to permit linking proprietary applications with the library.  If this is what 
you want to do, use the GNU Lesser General Public License instead of this License.
