operation manual

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.
4. Conveying Verbatim Copies.
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.
5. 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.
6. 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 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
