(3). FCC/Industry Canada Statement (to be placed on End Products) Federal Communications Commission (FCC) Statement 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.
FCC RF Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must follow the specific operating instructions for satisfying RF exposure compliance. This transmitter must not be co‐located or operating in conjunction with any other antenna or transmitter. Industry Canada (IC) Statement This device complies with Industry Canada’s licence-exempt RSSs.
Notice to OEM integrator The end user manual shall include all required regulatory information/warning as show in this manual. The OEM integrator is responsible for testing their end‐product for any additional compliance requirements required with this module installed. If the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module.
