Epson Powerlite Pro G5550nl Users Guide

							Notices181 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 (including consumables). 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.
■Take the following precautions when handling the plug: Do not 
overload wall outlets, extension cords, or power strips. Do not hold the 
plug with wet hands. Do not insert the plug into a dusty outlet. 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 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.
■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 block the light coming from the projector with any object. The 
object may be damaged or the reflected light may heat the lens and 
damage the projector.
■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.

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 
						

							186Notices
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.
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 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. 
						

							Notices187
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 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. 
						

							188Notices
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 compliance. 
						

							Notices189
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.
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. 
						

							190Notices
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.
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 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.
