Additional testing, Part 15 Subpart B disclaimer The final host / module combination need to be evaluated against the FCC Part 15B criteria for unintentional radiators in order to be properly authorized for operation as a Part15 digital device. The host integrator installing this module into their product must ensure that the final composite product complies with the FCC requirements by a technical assessment or evaluation to the FCC rules, including the transmitter operation and should refer to guidance in KDB 996369. For host products with certified modular transmitter, the frequency range of investigation of the composite system is specified by rule in Sections 15.33(a)(1) through (a)(3), or the range applicable to the digital device, as shown in Section 15.33(b)(1), whichever is the higher frequency range of investigation. When testing the host product, all the transmitters must be operating. The transmitters can be enabled by using publiclyavailable drivers and turned on, so the transmitters are active. In certain conditions it might be appropriate to use a technology-specific call box (test set) where accessory devices or drivers are not available. When testing for emissions from the unintentional radiator, the transmitter shall be placed in the receive mode or idle mode, if possible. If receive mode only is not possible then, the radio shall be passive (preferred) and/or active scanning. In these cases, this would need to enable activity on the communication BUS (i.e., PCIe, SDIO, USB) to ensure the unintentional radiator circuitry is enabled. Testing laboratories may need to add attenuation or filters depending on the signal strength of any active beacons (if applicable) from the enabled radio(s). See ANSI C63.4, ANSI C63.10 and ANSI C63.26 for further general testing details. 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. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

We, Butlr Technologies Inc., hereby declare that the product: Butlr Wireless Module, FCC ID:2AZPC-B-WM-01. model: B-WM-01-B,B-WM-01-C is electrically identical with the model:

B-WM-01-A which was tested by China Certification ICT Co., Ltd (Dongguan) with the same electromagnetic emissions and electromagnetic compatibility characteristics. The antenna parts of the wireless models have been designed based on compatibility, below figures are the schematic design and PCB layout. Descriptions of the differences among the three models that are declared similar are as follows.They are almost the same product and just the different model name and antenna types are different:

1) B-WM-01-B:

External antenna locates outside and connects to the PCBA by using connector. This model removes R2 and C13 components and keeps R1 and J1 components for antenna function, 2) B-WM-01-A and B-WM-01-C:

Their antennas both locate on PCBA and just the different model name means different antenna manufacturer.The two models remove R1 and J1 components and keeps R2 and C13 components for antenna function The rest are the same.The detail information,please check the reports. Please contact me should there be need for any additional clarification or information. Best Regards, Signature:
