The module has been tested and found to comply with U.S. Federal
Communications Commission (FCC) limits for a Class A digital device,
pursuant to Part 15 of the FCC rules. These limits provide reasonable
protection against harmful interference when the module operates in a
commercial environment.
The module can radiate radio frequency energy and, if not installed and
