FCC application
This device complies with Part 15 of the FCC Rules . Operation is subject to the following two conditions: this device may not cause harmful interference, and this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 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.
MPE Requirements
To satisfy FCC RF exposure requirements, a separation distance of 20 cm or
more should be maintained between the antenna of this device and persons
during device operation. To ensure compliance, operations at closer than this
distance is not recommended.
Region Selection
Limited by local law regulations, the version for North America does not
have region selection option.
Label
Host labeling requirement: Contains transmitter module FCC ID：2AXSR-
COZYMATE001.

Limited module procedures
The module is a single module, so this requirement is not applicable to the
product.
Trace antenna designs
The module uses the permanent PIFA antenna, so this requirement is not
applicable to the product.
RF exposure considerations
The host device manufacturer should confirm that a separation distance of
20 cm or more should be maintained between the antenna of this host device and
persons during the host device operation.
Antennas
For Bluetooth: PCB antenna, 3.0dBi
Label and compliance information
If this certified module is installed inside the host device, then the
outside of the host must be labeled with “Contains FCC ID: 2AXSR-COZYMATE001
”.
Information on test modes and additional testing requirements
The host manufacturer can use the software of Combo Tool to make the
Bluetooth transmit continuously, and the software of QA Tool to make the wifi
transmit continuously.
Additional testing, Part 15 Subpart B disclaimer
The module only complies with the FCC Part 15.247. If the module is
installed in the host device, the host manufacturer is responsible for
compliance to any other FCC rules that apply to the host not covered by the
modular transmitter grant of certification. For example, if the host
manufacturer markets their product as being Part 15 Subpart B compliant (when
it also contains unintentional-radiator digital circuity), then the host
manufacturer shall provide a notice stating that the final host product still
requires Part 15 Subpart B compliance testing with the modular transmitter
installed.
