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. To maintain compliance with FCCs RF Exposure guidelines, This equipment should be installed and operated with minimum distance between 20cm the radiator your body: Use only the supplied antenna. This product should not collocate with other radio. If the FCC identification number 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. This exterior label can use wording such as the following: Contains Transmitter Module FCC ID: 2AH9Q-BLUETOOTH01 or Contains FCC ID: 2AH9Q-BLUETOOTH01. The modules antenna is internal antenna, and the antenna cant be replaced.
(a)The module should not collocate with other wireless radio
(b) PCB antenna of antenna OEM should be use. Antenna Gain is 0dBi to connect with the antenna seat. 6
