Use of Bluetooth specifications by members of Bluetooth SIG is governed by the membership

agreements posted on Bluetooth SIG’s website located at www.bluetooth.com. Any use of this
specification by a member that is not in compliance with the applicable membership and other
related agreements is prohibited and, among other things, may result in (i) termination of the
applicable agreements and (ii) liability for infringement of the intellectual property rights of
Bluetooth SIG and its members. This specification may provide options, because, for example,
some products do not implement every portion of the specification. Each option identified in the
specification is intended to be within the bounds of the Scope as defined in the Bluetooth
Patent/Copyright License Agreement (“PCLA”). Also, the identification of options for
implementing a portion of the specification is intended to provide design flexibility without
establishing, for purposes of the PCLA, that any of these options is a “technically reasonable
non-infringing alternative.”
Use of this specification by anyone who is not a member of Bluetooth SIG is prohibited and is an
infringement of the intellectual property rights of Bluetooth SIG and its members. The furnishing

AND DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY
WARRANTIES OF MERCHANTABILITY, TITLE, NON-INFRINGEMENT, FITNESS FOR ANY
PARTICULAR PURPOSE, OR THAT THE CONTENT OF THIS SPECIFICATION IS FREE OF
ERRORS. For the avoidance of doubt, Bluetooth SIG has not made any search or investigation
as to third parties that may claim rights in or to any specifications or any intellectual property that
may be required to implement any specifications and it disclaims any obligation or duty to do so.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, BLUETOOTH SIG, ITS
MEMBERS AND THEIR AFFILIATES DISCLAIM ALL LIABILITY ARISING OUT OF OR
RELATING TO USE OF THIS SPECIFICATION AND ANY INFORMATION CONTAINED IN
THIS SPECIFICATION, INCLUDING LOST REVENUE, PROFITS, DATA OR PROGRAMS, OR
BUSINESS INTERRUPTION, OR FOR SPECIAL, INDIRECT, CONSEQUENTIAL,
INCIDENTAL OR PUNITIVE DAMAGES, HOWEVER CAUSED AND REGARDLESS OF THE
THEORY OF LIABILITY, AND EVEN IF BLUETOOTH SIG, ITS MEMBERS OR THEIR
AFFILIATES HAVE BEEN ADVISED OF THE POSSIBILITY OF THE DAMAGES.
Products equipped with Bluetooth wireless technology ("Bluetooth Products") and their
combination, operation, use, implementation, and distribution may be subject to regulatory
controls under the laws and regulations of numerous countries that regulate products that use
wireless non-licensed spectrum. Examples include airline regulations, telecommunications
regulations, technology transfer controls, and health and safety regulations. You are solely
responsible for complying with all applicable laws and regulations and for obtaining any and all
required authorizations, permits, or licenses in connection with your use of this specification and
development, manufacture, and distribution of Bluetooth Products. Nothing in this specification
provides any information or assistance in connection with complying with applicable laws or
regulations or obtaining required authorizations, permits, or licenses.

not the final version adopted by Bluetooth SIG’s Board of Directors, it may not be adopted. Any
specification adopted by Bluetooth SIG’s Board of Directors may be withdrawn, replaced, or
modified at any time. Bluetooth SIG reserves the right to change or alter final specifications in
