2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate the equipment.
NOTE:
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation.
This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, 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.
This module must be installed and operated in accordance with provided instructions and the antenna used for this
transmitter must be installed to provied a separation distance of at least 20 cm from all persons and must not be
co-located or operating in conjunction with any other antenna or transmitter. End-uses and installers must be
provide with antenna installation instructions and transmitter operating conditions for satisfying RF exposure
compliance.
Host device of OEM integrator must be labeled with: CONTAINS TX FCC ID: YWTWF53721MX
