FCC Radio Frequency Interference Warnings & Instructions
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 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 methods:
-
Reorient or relocate the receiving antenna
-
Increase the separation between the equipment and the receiver
-
Connect the equipment into an electrical outlet on a circuit different from that which the radio receiver is connected
-
Consult the dealer or an experienced radio/TV technician for help.
Modifications made to the product, unless expressly approved by LumenRadio AB, could void the user’s right to operate the equipment.

Compliance Marking¶
FCC & Industry Canada
The MiraOne modules are certified for FCC as a single-modular transmitter.
MiraOne modules are FCC certified radio module that carries a “Modular” grant. MiraOne radio modules complies to the “Intentional Radiator” portion (Part 15c) for FCC certification: Part 15.247 Transmitter tests.
An end product, incorporating a MiraOne module, does not require additional testing or authorization for the MiraOne transceiver. Host end products can use the FCC ID of the certified module as the FCC ID of the host end product. A label displaying the MiraOne module’s FCC ID must be affixed and visible on the host end product for approval.
FCC IDs are required for host end products with radio transmitters.
Other Compliances
For other local compliance regulations (CE, UL, CSA, SRRC, C-Tick, etc.) you are responsible as the product manufacturer to ensure all required compliance testing is completed. LumenRadio are happy to advise on compliance testing – please contact LumenRadio for details.
