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)
