•Do not use or store the projector in places where high and low temperature extremes occur, or where the temperature can change suddenly.
•Do not set up the projector in places where it might be subjected to vibration or shock.
•Do not set up the projector near high-voltage electrical wires or sources of magnetic fields.
•Do not store the projector standing on its side.
•Do not block the slots and openings in the projector case. They provide ventilation and prevent the projector from overheating. If you are setting up the 
projector near a wall, leave at least 19.7 inches (50 cm) of space between the wall and the air exhaust vent.
•Do not operate the projector in a closed-in cabinet unless proper ventilation is provided.
•You may need to clean the air filter and intake vent. A clogged air filter or vent can block ventilation needed to cool the projector.
•Do not use or store the projector outdoors for an extended length of time.
•Do not use the projector outside the required temperature range (sp.201). Doing so may cause an unstable display and could lead to projector damage.
•Do not store the projector outside the required temperature range (sp.201) or in direct sunlight for long periods of time. Doing so may cause damage 
to the case.
•Do not touch the plug during an electrical storm. Otherwise, you may receive an electric shock.
•Unplug the projector when it will not be used for extended periods. Place the projector near an outlet where the plug can be easily unplugged.
•Unplug the projector from the wall outlet and refer servicing to qualified service personnel under the following conditions: If it does not operate normally 
when you follow the operating instructions, or exhibits a distinct change in performance; If smoke, strange odors, or strange noises come from the 
projector; If the power cord or plug is damaged or frayed; If liquid or foreign objects get inside the projector, or if it has been exposed to rain or water; If 
it has been dropped or the housing has been damaged.
•Except as specifically explained in this User’s Guide, do not attempt to service this product yourself. Refer all servicing to qualified personnel. Opening 
or removing covers may expose you to dangerous voltages and other hazards.
•Never open any covers on the projector except as specifically explained in this User’s Guide. Never attempt to disassemble or modify the projector. Refer 
all repairs to qualified service personnel.
•Use the type of power source indicated on the projector. Use of a different power source may result in fire or electric shock. 
If you are not sure of the 
power available, consult your dealer or power company.
•If you use the projector in the country where it was purchased, only use the power cable that came with the projector. If you use the projector in a country 
other than where you purchased it, use the correct power cord for that country.
•Do not overload wall outlets, extension cords, or power strips. Do not insert the plug into a dusty outlet. This can cause fire or electric shock. 
						

							General Notes
212
•Take the following precautions when handling the plug: Do not hold the plug with wet hands. Insert the plug firmly into the outlet. Do not pull the power 
cord when disconnecting the plug; always be sure to hold the plug when disconnecting it. Failure to comply with these precautions could result in fire or 
electric shock.
•Do not place the projector where the cord can be walked on.
• The lamp(s) in this product contain mercury. Please consult your state and local regulations regarding disposal or recycling. Do not put in the trash.
•Do not place anything that can become warped or damaged by heat near the exhaust vents. Do not bring your hands or face close to the vents while 
projection is in progress.
•Do not bring your face close to the projector while it is in use.
•Do not disassemble or damage the lamp or subject it to any impacts.
•Before you move the projector, make sure its power is turned off, the plug is disconnected from the outlet, and all cables are disconnected.
•Do not project images while the detachable lens cover is still attached. Heat may cause the lens cover to melt, and if you touch the lens cover you could 
get burned.
•Do not touch the lens with bare hands.
•Always attach the lens cover to the lens when not using the projector, to prevent the lens from becoming dirty or damaged.
•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 your eyes or mouth. If you 
do inhale gases or gases come in contact with your eyes or mouth, seek medical advice immediately.
•If the projector is mounted overhead and the lamp breaks, be careful to prevent pieces of glass from falling into your eyes when you open the lamp cover.

The GNU General Public License Version 2 is as follows. You also can see the GNU
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 Foundation’s 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.
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 author’s 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. 
						

							General Notes
216
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 everyone’s 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 Program" 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 Program 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.
1. You may copy and distribute verbatim copies of the Program’s 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. 
						

							General Notes
217
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:
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 c
ompliance.
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. 
						

							General Notes
218
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.
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 aversion 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.
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 
						

							General Notes
219
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 FOR 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)  
This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free 
Software Foundation; either version 2 of the License, or (at your option) any later version.
This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of 
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 
Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
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. 
						

							General Notes
220
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.
, 1 April 1989
Ty Coon, President of Vice
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.
