This modular should be installed and operated with minimum distance 20 cm between the radiator& your body. 3. The maximum antenna gain is 0dBi.For situations where the host manufacturer is responsible for an external connector, the integration instructions shall inform the installer that a unique antenna connector must be used on the Part 15 authorized transmitters used in the host product. 4. When the module is installed in the host device, the FCC ID label must be visible through a window on the final device or it must be visible when an access panel, door or cover is easily removed. If not, a second label must be placed on the outside of the final device that contains the following text: ―Contains FCC ID: 2AWQ6BT11 5. The Xiamen Apt Electronic Tech. Co., Ltd uses various test mode programs for test set up which operate separate from production firmware. Host integrators should contact Xiamen Apt Electronic Tech. Co., Ltd for assistance with test modes needed for module/host compliance test requirements. 6. The Xiamen Apt Electronic Tech. Co., Ltd Bluetooth module is FCC authorized for the FCC Part15.247 listed on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the Bluetooth module grant of certification. If the grantee markets their product as being Part 15 Subpart B compliant, then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the Bluetooth module installed. 7. The module is limited to use in the host.the host FCC ID is 2AWQ6CB821,product name is thermal printer,main model is CB821-USEB. the limited module manufacturer reviews detailed test data or host designs prior to giving the host manufacturer approval.
