FCC Warning Statement Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 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 antenna. ‐‐ 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.

Bluetooth Speaker Model No.: BTS-12 Internal Battery: 3.7V Input: 5 V FCC ID: RMZBTS-12 Richen Industrial Co., Ltd. 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.

Maximum Permissible Exposure Applicable Standard Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess limit for maximum permissible exposure. In accordance with 47 CFR FCC Part 2 Subpart J, section 2.1091 this device has been defined as a mobile device whereby a distance of 0.2m normally can be maintained between the user and the device.
