FCC Warnings

This equipment is intended for use in a laboratory test environment only. It generates, uses, and can radiate radio frequency
energy and has not been tested for compliance with the limits of computing devices pursuant to subpart J of part 15 of FCC rules,
which are designed to provide reasonable protection against radio frequency interference. Operation of this equipment in other
environments may cause interference with radio communications, in which case the user at his own expense will be required to
take whatever measures may be required to correct this interference.

EVM TERMS AND CONDITIONS

Texas Instruments (TI) provides the enclosed Evaluation Module and related material (EVM) to you, the user, (you or user)
SUBJECT TO the terms and conditions set forth below. By accepting and using the EVM, you are indicating that you have read,
understand and agree to be bound by these terms and conditions. IF YOU DO NOT AGREE TO BE BOUND BY THESE TERMS
AND CONDITIONS, YOU MUST RETURN THE EVM AND NOT USE IT.

This EVM is provided to you by TI and is intended for your INTERNAL ENGINEERING DEVELOPMENT OR EVALUATION
PURPOSES ONLY
. It is provided “AS IS” and “WITH ALL FAULTS.” It is not considered by TI to be fit for commercial use. As
such, the EVM may be incomplete in terms of required design-, marketing-, and/or manufacturing-related protective considerations,
including product safety measures typically found in the end product. As a prototype, the EVM does not fall within the scope of the
European Union directive on electromagnetic compatibility and therefore may not meet the technical requirements of the directive.

Should this EVM not meet the specifications indicated in the EVM User’s Guide, it may be returned within 30 days from the date of
delivery for a full refund of any amount paid by user for the EVM, which user agrees shall be user’s sole and exclusive remedy.
THE FOREGOING WARRANTY IS THE EXCLUSIVE WARRANTY MADE BY TI TO USER, AND IS IN LIEU OF ALL OTHER
WARRANTIES, EXPRESSED, IMPLIED, OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS
FOR ANY PARTICULAR PURPOSE OR NON-INFRINGEMENT.

TI shall have no obligation to defend any claim arising from the EVM, including but not limited to claims that the EVM infringes third
party intellectual property. Further, TI shall have no liability to user for any costs, losses or damages resulting from any such
claims. User shall indemnify and hold TI harmless against any damages, liabilities or costs resulting from any claim, suit or
proceeding arising from user’s handling or use of the EVM, including but not limited to, (i) claims that the EVM infringes a third
party’s intellectual property, and (ii) claims arising from the user’s use or handling of the EVM. TI shall have no responsibility to
defend any such claim, suit or proceeding.

User assumes all responsibility and liability for proper and safe handling and use of the EVM and the evaluation of the EVM. TI
shall have no liability for any costs, losses or damages resulting from the use or handling of the EVM. User acknowledges that the
EVM may not be regulatory compliant or agency certified (FCC, UL, CE, etc.). Due to the open construction of the EVM it is the
user’s responsibility to take any and all appropriate precautions with regard to electrostatic discharge.

EXCEPT TO THE EXTENT OF THE USER’S INDEMNITY OBLIGATIONS SET FORTH ABOVE, NEITHER PARTY SHALL BE
LIABLE TO THE OTHER FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES WHETHER TI IS
NOTIFIED OF THE POSSIBILITY OR NOT.

TI currently deals with a variety of customers for products, and therefore our arrangement with the user is not exclusive.

TI assumes no liability for applications assistance, customer product design, software performance, or infringement of
patents or services described herein.

User agrees to read the EVM User’s Guide and, specifically, the EVM warnings and Restrictions notice in the EVM User’s Guide
prior to handling the EVM and the product. This notice contains important safety information about temperatures and voltages.

It is user’s responsibility to ensure that persons handling the EVM and the product have electronics training and observe good
laboratory practice standards.

By providing user with this EVM, product and services, TI is NOT granting user any license in any patent or other intellectual
property right.

EVM WARNINGS AND RESTRICTIONS

It is important to operate this EVM within the input voltage range of 2.7 V to 5.5 V and the output
voltage range of 2.5 V to 5.5 V.

Exceeding the specified input range may cause unexpected operation and/or irreversible damage
to the EVM. If there are questions concerning the input range, please contact a TI field
representative prior to connecting the input power.

Applying loads outside of the specified output range may result in unintended operation and/or
possible permanent damage to the EVM. Please consult the EVM User's Guide prior to
connecting any load to the EVM output. If there is uncertainty as to the load specification, please
contact a TI field representative.
