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-x53BU User Guide
Notices 46
Page: 47
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-x53BU User Guide
Notices 47
Page: 48
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-x53BU User Guide
Notices 48
Page: 49
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-x53BU User Guide
Notices 49
Page: 50
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:
