However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment to an outlet on a circuit different from that to which the television receiver is connected. 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. Note: Modifications to this product will void the users authority to operate this equipment. RF Radiation Exposure Statement:
1.This Transmitter must not be colocated or operating in conjunction with any other antenna or transmitter. 2.This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body. FCC Information to OEM integrator The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user manual of the end product. The user manual which is provided by OEM integrators for end users must include the following information in a prominent location. 1.To comply with FCC RF exposure compliance requirements, the antenna used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co located or operating in conjunction with any other antenna or transmitter, except in accordance with FCC multitransmitter product procedures. 2. Only those antennas with same type and lesser gain filed under this FCC ID number can be used with this device. 3. The regulatory label on the final system must include the statement: Contains FCC ID: 2ACP4-
SPBPT or using electronic labeling method as documented in KDB 784748. 4. The final system integrator must ensure there is no instruction provided in the user manual or customer documentation indicating how to install or remove the transmitter module except such device has implemented twoways authentication between module and the host system AC410x family+BT-V2.0 Users Manual 14 3/14/2014
