Federal Communication Commission Interference Statement
FCC NOTE (for U.S.A):
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 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.
Radiation Exposure Statement
This device complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This device should be installed and operated with minimum distance 20cm between the radiator & your
body and must not be co-located in conjunction with any other antenna or transmitter.
The host device itself and with integrated RF module needs to comply with the FCC regulations.
The OEM integrator is still responsible for the FCC compliance requirement of the end product, which
integrates this module. Appropriate measurements (e.g. 15 B compliance) and if applicable additional
equipment authorizations (e.g. Verification , Doc) of the host device to be addressed by the integrator /
manufacturer."
Labelling Information
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.
Caution: Any changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate this equipment.
