simultaneously transmitting modules or other transmitters in a host.

FCC PART 15 SUBPART B DISCLAIMER

FCC Information to Users
This equipment has been tested and found to comply with the limits for a Class B digital devices,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in user’s installation. 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. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help.
