REGULATORY COMPLIANCE INFORMATION

As noted in the EVM User’s Guide and/or EVM itself, this EVM and/or accompanying hardware may or may not be subject to the Federal
Communications Commission (FCC) and Industry Canada (IC) rules.

For EVMs

not

subject to the above rules, this evaluation board/kit/module is intended for use for ENGINEERING DEVELOPMENT,

DEMONSTRATION OR EVALUATION PURPOSES ONLY and is not considered by TI to be a finished end product fit for general consumer
use. It generates, uses, and can radiate radio frequency energy and has not been tested for compliance with the limits of computing
devices pursuant to part 15 of FCC or ICES-003 rules, which are designed to provide reasonable protection against radio frequency
interference. Operation of the equipment 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.

General Statement for EVMs including a radio

User Power/Frequency Use Obligations: This radio is intended for development/professional use only in legally allocated frequency and
power limits. Any use of radio frequencies and/or power availability of this EVM and its development application(s) must comply with local
laws governing radio spectrum allocation and power limits for this evaluation module. It is the user’s sole responsibility to only operate this
radio in legally acceptable frequency space and within legally mandated power limitations. Any exceptions to this are strictly prohibited and
unauthorized by Texas Instruments unless user has obtained appropriate experimental/development licenses from local regulatory
authorities, which is responsibility of user including its acceptable authorization.

For EVMs annotated as FCC – FEDERAL COMMUNICATIONS COMMISSION Part 15 Compliant
Caution

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause
harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the
equipment.

FCC Interference Statement for Class A EVM devices

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be required to correct the interference at his own expense.
