Regulatory USA The IK-CSR8645 module has been labeled with its own FCC ID number, and if the FCC ID is not visible when the module is installed inside host audio device. Then the outside of the finished product into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording as follows: Contains FCC ID: VNH-IK-CSR8645 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 A user’s manual for the product should include the following statement The following statement must be included as a CAUTION statement in manuals to alert users of FCC RF exposure compliance:
