Product Usage Instructions
- This module should be installed in the host device according to
the interface specification. - For users in Canada, the host device must comply with
Innovation, Science and Economic Development Canada’s applicable
licence-exempt RSSs. The device should not cause interference and
must accept any interference that may cause undesired operation of
the device. - For users in the United States, the host device must comply
with part 15 of the FCC Rules. The device should not cause harmful
interference and must accept any interference received, including
interference that may cause undesired operation. - The host device or user manual of the host device should
indicate the following statement: “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.” - The product contains a transmitter module with FCC ID:
2A6NFES2811. If the FCC ID is not visible when the module is
installed inside another device, then the module is installed must
also display a label referring to the enclosed module. - Any changes or modifications not approved by the party

operate the equipment. - The modular transmitter is only FCC authorized for specific
rule parts listed on the grant. The host product manufacturer is
responsible for compliance with any other FCC rules that apply to
the host not covered by the modular transmitter grant of
certification. The final host product still requires Part 15
Subpart B compliance testing with the modular transmitter
installed. - The antenna used for this transmitter must not be co-located or
operating in conjunction with any other antenna or
transmitter. - The output power of the module can only be changed by the
application software developed by the module installer. End users
cannot change the output power. - Antenna List: No.1 – Antenna Category: Monopole
