FCC Conformance information
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 causeu desired 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 to 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.
This device is intended only for OEM integrators under the following conditions: (For module device use)
- The antenna must be installed such that 20 cm is maintained between the antenna and the users, and
- The transmitter module may not be co located with any other transmitter or antenna. As long as 2 conditions above are met, further transmitter test will not be required.
However, the OEM integrator is still responsible for testing their end product for any additional compliance requirements required with this module installed.
Important Notice to OEM integrators
- This module is limited to OEM installation ONLY.
- This module is limited to installation in mobile applications, according to Part 2.1091(b).
- The separate approval is required for all other operating configurations, including portable configurations with respect to Part 2.1093 and different antenna configurations
- For FCC Part 15.31 (h) and (k): The host manufacturer is responsible for additional testing to verify compliance as a composite system. When testing the host device for compliance with Part 15 Subpart B, the host manufacturer is required to show compliance with Part 15 Subpart B while the transmitter module (s) are installed and operating. The modules should be transmitting, and the evaluation should confirm that the module’s intentional emissions are compliant (i.e., fundamental and out-of-band emissions). The host manufacturer must verify that there are no additional unintentional emissions other than what is permitted in Part 15 Subpart B, or that emissions are compliant with the transmitter(s) rule(s). The Grantee will provide guidance to the host manufacturer for Part 15 B requirements if needed.
Important Note
Notice that any deviation(s) from the defined parameters of the antenna trace, as described by the instructions, require that the host product manufacturer must notify Rolling Wireless S.a.r.l… that they wish to change the antenna trace design. In this case, a Class IIA permissive change application is required to be filed by the USI, or the host manufacturer can take responsibility through the change in FCC ID (new application) procedure, followed by a Class II permissive change application.
End Product Labeling
When the module is installed in the host device, the FCC label must be visible through a window on the final device or it must be visible when an access panel, door or cover is easily removed. If not, a second label must be placed on the outside of the final device that contains the following text: “Contains FCC ID: 2AX2URW 520GL.” The FCC ID can be used only when all FCC compliance requirements are met.
Antenna Installation
- The antenna must be installed such that 20 cm is maintained between the antenna and the users.
- The transmitter module may not be co-located with any other transmitter or antenna.
- Only antennas of the same type and with equal or less gain than those shown below may be used with this module. Other types of antennas and/or higher gain antennas may require additional authorization for operation.
In the event that these conditions cannot be met (for example, certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid, and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for reevaluating the end product (including the transmitter) and obtaining a separate FCC authorization.

Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product that integrates this module. The end user manual shall include all required regulatory information/warnings as shown in this manual.
Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance 20 cm between the radiator & your body.47 CFR Part 22, 24, 27, 90 This module can be used in IOT devices; the input voltage to the module is nominally 3. 3V. This module is a single module. The antenna is not a trace antenna.
IC Conformance information
Industry Canada Statement
This device complies with Industry Canada’s licence-exempt RSSs. Operation is subject to the following two conditions:
- This device may not cause interference, and
- This device must accept any interference, including interference that may cause undesired operation of the device.
Radiation Exposure Statement
This equipment complies with IC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20 cm between the radiator & your body.
This device is intended only for OEM integrators under the following conditions: (For module device use)
- The antenna must be installed such that 20 cm is maintained between the antenna and the users, and
- The transmitter module may not be co-located with any other transmitter or antenna. As long as 2 conditions above are met, further transmitter tests will not be required. However, the OEM integrator is still responsible for testing their end product for any additional compliance requirements required with this module installed.
IMPORTANT NOTE
In the event that these conditions cannot be met (for example, certain laptop configurations or colocation with another transmitter ), then the Canada authorization is no longer considered valid, and the IC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including thetransmitter) and obtaining a separate Canada authorization.
End Product Labeling
This transmitter module is authorized only for use in devices where the antenna may be installed such that 20 cm may be maintained between the antenna and the users. The final end product must be labeled in a visible area with the following: “Contains IC: 26644 RW 520GL
