Applications Soundbar and Subwoofer (FW dependent) Bluetooth portable speaker phone Multi-speaker (FW dependent) Bluetooth headset www.sunitec-cn.com BMS001 User Manual FCC Statement List of applicable FCC rules This device complies with FCC part 15C : 15.247. Specific operational use conditions This device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter. And the module should be installed at a minimum distance of 5 mm away from person nearby. The host product manufacturer should state this information to the host instruction manual. Limited module proceduresApplicable. ( See the "Features", "Applications" of the catalog) Manufacturer reviews detailed test data or host designs prior to giving the host manufacturer approval. The module is installed in the host, and the host needs to be tested according to relevant regulations. For additional hosts other than the specific host originally granted with a limited module, a C2PC application is required on the module grant to register the additional host as a specific host also approved with the module. Trace antenna designsNot applicable. FCC Radiation Exposure Statement This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. This modular must be installed and operated with a minimum distance of 5 mm between the radiator and user body. Antenna Information Antenna Type: PCB Antenna Antenna Gain: 2.84 dBi The antenna is permanently attached and not consideration of replacement. Label and compliance information 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. Caution: The user is cautioned that changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 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 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. If the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: Contains Transmitter Module FCC ID: 2AMX3BMS001 Or Contains FCC ID: 2AMX3BMS001. Information on test modes and additional testing requirements Any final host product with the modular transmitter installed should be under test according to guidance given in KDB 996369 D04. To enter test mode for module, WCN_combo_tool software and command is necessary. When something wrong happens in configuring test modes for host product with module, host product manufacturer should coordinate with module manufacturer for technical support. It is recommended that some investigative measurements should be taken to confirm that host product with module installed does not exceed the spurious emissions limits or band edge limits. Part 15 Subpart B disclaimer The modular transmitter is only FCC authorized for the specific rule parts (FCC Part 15.247) list 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 modular transmitter grant of certification.
