Federal Communication Commission Interference Statement
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.
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.
Any changes or modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate this equipment. This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.
List of applicable FCC rules
This module has been tested and found to comply with part 22, part 24, part 27, part 90, part 96
requirements for Modular Approval.
The modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules)
listed on the grant, and that the host product manufacturer is responsible for compliance to any other
FCC rules that apply to the host not covered by the modular transmitter grant of certification. If the
grantee markets their product as being Part 15 Subpart B compliant (when it also contains unintentional-
radiator digital circuity), then the grantee shall provide a notice stating that the final host product still
requires Part 15 Subpart B compliance testing with the modular transmitter installed.
