GNU Public License
Version 3, 29 June 2007
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not
allowed.
Preamble
The GNU General Public License is a free, copy left license for software and other kinds of works.
The licenses for most software and other practical works are designed to take away your freedom to share
and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom
to share and change all versions of a program--to make sure it remains free software for all its users. We, the
TS-x73U User Guide
Notices 56
Free Software Foundation, use the GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. 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 them 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 prevent others from denying you these rights or asking you to surrender
the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify
it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the
recipients the same freedoms that you received. 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.
Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software,
and (2) offer you this License giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free
software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed,
so that their problems will not be attributed erroneously to authors of previous versions.
Some devices are designed to deny users access to install or run modified versions of the software inside
them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting
users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products
for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this
version of the GPL to prohibit the practice for those products. If such problems arise substantially in other
domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed
to protect the freedom of users.
Finally, every program is threatened constantly by software patents. States should not allow patents to
restrict development and use of software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could make it effectively proprietary. To
prevent this, the GPL assures that patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and modification follow.
Terms and Conditions
1. Definitions.
“This License” refers to version 3 of the GNU General Public License.
“Copyright” also means copyright-like laws that apply to other kinds of works, such as semiconductor
masks.
“The Program” refers to any copyrightable work licensed under this License. Each licensee is
addressed as “you”. “Licensees” and “recipients” may be individuals or organizations.
To “modify” a work means to copy from or adapt all or part of the work in a fashion requiring copyright
permission, other than the making of an exact copy. The resulting work is called a “modified version” of
the earlier work or a work “based on” the earlier work.
A “covered work” means either the unmodified Program or a work based on the Program.
To “propagate” a work means to do anything with it that, without permission, would make you directly or
secondarily liable for infringement under applicable copyright law, except executing it on a computer or
modifying a private copy. Propagation includes copying, distribution (with or without modification),
making available to the public, and in some countries other activities as well.
To “convey” a work means any kind of propagation that enables other parties to make or receive
copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not
conveying.
An interactive user interface displays “Appropriate Legal Notices” to the extent that it includes a
convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2)
TS-x73U User Guide
Notices 57
tells the user that there is no warranty for the work (except to the extent that warranties are provided),
that licensees may convey the work under this License, and how to view a copy of this License. If the
interface presents a list of user commands or options, such as a menu, a prominent item in the list
meets this criterion.
2. Source Code.
The “source code” for a work means the preferred form of the work for making modifications to it.
“Object code” means any non-source form of a work.
A “Standard Interface” means an interface that either is an official standard defined by a recognized
standards body, or, in the case of interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The “System Libraries” of an executable work include anything, other than the work as a whole, that (a)
is included in the normal form of packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that Major Component, or to implement
a Standard Interface for which an implementation is available to the public in source code form. A
“Major Component”, in this context, means a major essential component (kernel, window system, and
so on) of the specific operating system (if any) on which the executable work runs, or a compiler used
to produce the work, or an object code interpreter used to run it.
The “Corresponding Source” for a work in object code form means all the source code needed to
generate, install, and (for an executable work) run the object code and to modify the work, including
scripts to control those activities. However, it does not include the work's System Libraries, or general-
purpose tools or generally available free programs which are used unmodified in performing those
activities but which are not part of the work. For example, Corresponding Source includes interface
definition files associated with source files for the work, and the source code for shared libraries and
dynamically linked subprograms that the work is specifically designed to require, such as by intimate
data communication or control flow between those subprograms and other parts of the work.
The Corresponding Source need not include anything that users can regenerate automatically from
other parts of the Corresponding Source.
The Corresponding Source for a work in source code form is that same work.
3. Basic Permissions.
All rights granted under this License are granted for the term of copyright on the Program, and are
irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a covered work is covered by this
License only if the output, given its content, constitutes a covered work. This License acknowledges
your rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not convey, without conditions so long as
your license otherwise remains in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you with facilities for running those
works, provided that you comply with the terms of this License in conveying all material for which you
do not control copyright. Those thus making or running the covered works for you must do so
exclusively on your behalf, under your direction and control, on terms that prohibit them from making
any copies of your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under the conditions stated below.
Sublicensing is not allowed; section 10 makes it unnecessary.
4. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological measure under any applicable law
fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such measures.
When you convey a covered work, you waive any legal power to forbid circumvention of technological
measures to the extent such circumvention is effected by exercising rights under this License with
respect to the covered work, and you disclaim any intention to limit operation or modification of the
work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid
circumvention of technological measures.
5. Conveying Verbatim Copies.
TS-x73U User Guide
Notices 58
You may convey 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; keep intact all notices stating that this License and any non-permissive terms added in accord
with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey, and you may offer support or
warranty protection for a fee.
6. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to produce it from the Program, in
the form of source code under the terms of section 4, provided that you also meet all of these
conditions:
a. The work must carry prominent notices stating that you modified it, and giving a relevant date.
b. The work must carry prominent notices stating that it is released under this License and any
conditions added under section 7. This requirement modifies the requirement in section 4 to “keep
intact all notices”.
c. You must license the entire work, as a whole, under this License to anyone who comes into
possession of a copy. This License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts, regardless of how they are packaged.
This License gives no permission to license the work in any other way, but it does not invalidate
such permission if you have separately received it.
d. If the work has interactive user interfaces, each must display Appropriate Legal Notices; however,
if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work
need not make them do so.
A compilation of a covered work with other separate and independent works, which are not by
their nature extensions of the covered work, and which are not combined with it such as to form a
larger program, in or on a volume of a storage or distribution medium, is called an “aggregate” if
the compilation and its resulting copyright are not used to limit the access or legal rights of the
compilation's users beyond what the individual works permit. Inclusion of a covered work in an
aggregate does not cause this License to apply to the other parts of the aggregate.
7. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of sections 4 and 5, provided that
you also convey the machine-readable Corresponding Source under the terms of this License, in one of
these ways:
a. Convey the object code in, or embodied in, a physical product (including a physical distribution
medium), accompanied by the Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b. Convey the object code in, or embodied in, a physical product (including a physical distribution
medium), accompanied by a written offer, valid for at least three years and valid for as long as you
offer spare parts or customer support for that product model, to give anyone who possesses the
object code either (1) a copy of the Corresponding Source for all the software in the product that
is covered by this License, on a durable physical medium customarily used for software
interchange, for a price no more than your reasonable cost of physically performing this conveying
of source, or (2) access to copy the Corresponding Source from a network server at no charge.
c. Convey individual copies of the object code with a copy of the written offer to provide the
Corresponding Source. This alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord with subsection 6b.
d. Convey the object code by offering access from a designated place (gratis or for a charge), and
offer equivalent access to the Corresponding Source in the same way through the same place at
no further charge. You need not require recipients to copy the Corresponding Source along with
TS-x73U User Guide
Notices 59
the object code. If the place to copy the object code is a network server, the Corresponding
Source may be on a different server (operated by you or a third party) that supports equivalent
copying facilities, provided you maintain clear directions next to the object code saying where to
find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you
remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
e. Convey the object code using peer-to-peer transmission, provided you inform other peers where
the object code and Corresponding Source of the work are being offered to the general public at
no charge under subsection 6d.
A separable portion of the object code, whose source code is excluded from the Corresponding
Source as a System Library, need not be included in conveying the object code work.
A “User Product” is either (1) a “consumer product”, which means any tangible personal property
which is normally used for personal, family, or household purposes, or (2) anything designed or
sold for incorporation into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular product received by a
particular user, “normally used” refers to a typical or common use of that class of product,
regardless of the status of the particular user or of the way in which the particular user actually
uses, or expects or is expected to use, the product. A product is a consumer product regardless of
whether the product has substantial commercial, industrial or non-consumer uses, unless such
uses represent the only significant mode of use of the product.
“Installation Information” for a User Product means any methods, procedures, authorization keys,
or other information required to install and execute modified versions of a covered work in that
User Product from a modified version of its Corresponding Source. The information must suffice
to ensure that the continued functioning of the modified object code is in no case prevented or
interfered with solely because modification has been made.
If you convey an object code work under this section in, or with, or specifically for use in, a User
Product, and the conveying occurs as part of a transaction in which the right of possession and
use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless
of how the transaction is characterized), the Corresponding Source conveyed under this section
must be accompanied by the Installation Information. But this requirement does not apply if
neither you nor any third party retains the ability to install modified object code on the User
Product (for example, the work has been installed in ROM).
The requirement to provide Installation Information does not include a requirement to continue to
provide support service, warranty, or updates for a work that has been modified or installed by the
recipient, or for the User Product in which it has been modified or installed. Access to a network
may be denied when the modification itself materially and adversely affects the operation of the
network or violates the rules and protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided, in accord with this section
must be in a format that is publicly documented (and with an implementation available to the
public in source code form), and must require no special password or key for unpacking, reading
or copying.
8. Additional Terms.
“Additional permissions” are terms that supplement the terms of this License by making exceptions
from one or more of its conditions. Additional permissions that are applicable to the entire Program
shall be treated as though they were included in this License, to the extent that they are valid under
applicable law. If additional permissions apply only to part of the Program, that part may be used
separately under those permissions, but the entire Program remains governed by this License without
regard to the additional permissions.
When you convey a copy of a covered work, you may at your option remove any additional permissions
from that copy, or from any part of it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place additional permissions on material,
added by you to a covered work, for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you add to a covered work, you may (if
authorized by the copyright holders of that material) supplement the terms of this License with terms:
TS-x73U User Guide
Notices 60
a. Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this
License; or
b. Requiring preservation of specified reasonable legal notices or author attributions in that material
or in the Appropriate Legal Notices displayed by works containing it; or
c. Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of
such material be marked in reasonable ways as different from the original version; or
d. Limiting the use for publicity purposes of names of licensors or authors of the material; or
e. Declining to grant rights under trademark law for use of some trade names, trademarks, or service
marks; or
f. Requiring indemnification of licensors and authors of that material by anyone who conveys the
material (or modified versions of it) with contractual assumptions of liability to the recipient, for any
liability that these contractual assumptions directly impose on those licensors and authors.
All other non-permissive additional terms are considered “further restrictions” within the meaning
of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further restriction, you may remove that term.
If a license document contains a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms of that license document,
provided that the further restriction does not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you must place, in the relevant
source files, a statement of the additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the form of a separately written
license, or stated as exceptions; the above requirements apply either way.
9. Termination.
You may not propagate or modify a covered work except as expressly provided under this License. Any
attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your license from a particular copyright holder is
reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your
license, and (b) permanently, if the copyright holder fails to notify you of the violation by some
reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is reinstated permanently if the copyright
holder notifies you of the violation by some reasonable means, this is the first time you have received
notice of violation of this License (for any work) from that copyright holder, and you cure the violation
prior to 30 days after your receipt of the notice.
Termination of your rights under this section does not terminate the licenses of parties who have
received copies or rights from you under this License. If your rights have been terminated and not
permanently reinstated, you do not qualify to receive new licenses for the same material under section
10.
10. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run a copy of the Program. Ancillary
propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to
receive a copy likewise does not require acceptance. However, nothing other than this License grants
you permission to propagate or modify any covered work. These actions infringe copyright if you do not
accept this License. Therefore, by modifying or propagating a covered work, you indicate your
acceptance of this License to do so.
11. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically receives a license from the original
licensors, to run, modify and propagate that work, subject to this License. You are not responsible for
enforcing compliance by third parties with this License.
TS-x73U User Guide
Notices 61
An “entity transaction” is a transaction transferring control of an organization, or substantially all assets
of one, or subdividing an organization, or merging organizations. If propagation of a covered work
results from an entity transaction, each party to that transaction who receives a copy of the work also
receives whatever licenses to the work the party's predecessor in interest had or could give under the
previous paragraph, plus a right to possession of the Corresponding Source of the work from the
predecessor in interest, if the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the rights granted or affirmed under this
License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights
granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in
a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or
importing the Program or any portion of it.
12. Patents.
A “contributor” is a copyright holder who authorizes use under this License of the Program or a work on
which the Program is based. The work thus licensed is called the contributor's “contributor version”.
A contributor's “essential patent claims” are all patent claims owned or controlled by the contributor,
whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by
this License, of making, using, or selling its contributor version, but do not include claims that would be
infringed only as a consequence of further modification of the contributor version. For purposes of this
definition, “control” includes the right to grant patent sublicenses in a manner consistent with the
requirements of this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the
contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify
and propagate the contents of its contributor version.
In the following three paragraphs, a “patent license” is any express agreement or commitment, however
denominated, not to enforce a patent (such as an express permission to practice a patent or covenant
not to sue for patent infringement). To “grant” such a patent license to a party means to make such an
agreement or commitment not to enforce a patent against the party.
If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of
the work is not available for anyone to copy, free of charge and under the terms of this License, through
a publicly available network server or other readily accessible means, then you must either (1) cause
the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of
this License, to extend the patent license to downstream recipients. “Knowingly relying” means you
have actual knowledge that, but for the patent license, your conveying the covered work in a country, or
your recipient's use of the covered work in a country, would infringe one or more identifiable patents in
that country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by
procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving
the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered
work, then the patent license you grant is automatically extended to all recipients of the covered work
and works based on it.
A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the
exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically
granted under this License. You may not convey a covered work if you are a party to an arrangement
with a third party that is in the business of distributing software, under which you make payment to the
third party based on the extent of your activity of conveying the work, and under which the third party
grants, to any of the parties who would receive the covered work from you, a discriminatory patent
license (a) in connection with copies of the covered work conveyed by you (or copies made from those
copies), or (b) primarily for and in connection with specific products or compilations that contain the
covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28
March 2007.
Nothing in this License shall be construed as excluding or limiting any implied license or other defenses
to infringement that may otherwise be available to you under applicable patent law.
13. No Surrender of Others' Freedom.
TS-x73U User Guide
Notices 62
If 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
convey a covered work so as to satisfy simultaneously your obligations under this License and any
other pertinent obligations, then as a consequence you may not convey it at all. For example, if you
agree to terms that obligate you to collect a royalty for further conveying from those to whom you
convey the Program, the only way you could satisfy both those terms and this License would be to
refrain entirely from conveying the Program.
14. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have permission to link or combine any
covered work with a work licensed under version 3 of the GNU Affero General Public License into a
single combined work, and to convey the resulting work. The terms of this License will continue to apply
to the part which is the covered work, but the special requirements of the GNU Affero General Public
License, section 13, concerning interaction through a network will apply to the combination as such.
15. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of the GNU 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 that a certain numbered
version of the GNU General Public License “or any later version” applies to it, you have the option of
following the terms and conditions either of that numbered version or of any later version published by
the Free Software Foundation. If the Program does not specify a version number of the GNU General
Public License, you may choose any version ever published by the Free Software Foundation.
If the Program specifies that a proxy can decide which future versions of the GNU General Public
License can be used, that proxy's public statement of acceptance of a version permanently authorizes
you to choose that version for the Program.
Later license versions may give you additional or different permissions. However, no additional
obligations are imposed on any author or copyright holder as a result of your choosing to follow a later
version.
16. Disclaimer of Warranty.
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.
17. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY
COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 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.
18. Interpretation of Sections 16 and 17.
If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect
according to their terms, reviewing courts shall apply local law that most closely approximates an
absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of
liability accompanies a copy of the Program in return for a fee.
