NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television 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 an　tenna. Increase the separation between the equipment and receiver.　 Connect the equipment into an outlet on a circuit different from that to which the 　receiver is connected. Consult the dealer or an experienced radio/TV technician for help.　 RF warning statement: The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction. Module Warning Statement: This Bluetooth module is designed to comply with the FCC statement, FCC ID is: 2ADQG-AB1126. The host system using this module, should have label in a visible area indicated the following texts: “Contains FCC ID: 2ADQG-AB1126”. This radio module must not be installed to co-locate and operated simultaneously with other radios in host system, additional testing and equipment authorization may be required to operating simultaneously with other radio.This Bluetooth module has a PCB antenna. While this module has no shielding, and therefore the host equipment shall add a shielding function, and any host with module installed, has to be retested, then additional equipment authorization shall be achieved on the host equipment that has the module installed.
