FCC Caution Any changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. 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. To maintain compliance with FCC exposure compliance requirement, please follow operation instruction as documented in this manual. FCC Label Instructions:

The outside of final products that contains this module device must display a label referring to the enclosed module. This exterior label can use wording such as: Contains Transmitter Module FCC ID:YAIBM20,or Contains FCC ID: YAIBM20, Any similar wording that expresses the same meaning may be used. 14/14
