FCC Statement 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. 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. The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction. Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01 2.2 List of applicable FCC rules FCC Part 15 Subpart C 15.247 & 15.209 2.3 Specific operational use conditions The module is a Bluetooth module with Bluetooth 5.0 low energy (BLE) function. Operation Frequency: 2402-2480MHz Number of Channel: 40 Modulation: GFSK Type: PCB Antenna Gain: 2 .6 dBi Max . The module can be used for mobile or portable applications with a maximum 2.6 dBi antenna. The host manufacturer installing this module into their product must ensure that the final composit product complies with the FCC requirements by a technical assessment or evaluation to the FCC rules, including the transmitter operaition. The host manufacturer has to be aware not to provide information to the end user regarding how to install or removethis RF module in the user's manual of the end product which integrates this module. The end user manual shall inc lude all required regulatory information/warning as show in this manual. 2.4 Limited module procedures Not applicable. The module is a Single module and complies with the requirement of FCC Part 15.212. 2.5 Trace antenna designs Not applicable. The module has its own antenna, and doesn’t need a host’s printed board microstrip trace antenna etc. 2.6 RF exposure considerations and if RF exposure statement or module layout is changed, then the host product manufacturer required to take responsibilit of the module through a change in FCC ID or new application. The FCC ID of the module cannot be used on the final product. In these circumstanc es, the host manufacturer will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. 2.7 Antennas Antenna Specification are as follows: Type: PCB Antenna Gain: 2.6 dBi This device is intended only for host manufacturers under the following conditions: The transmitter module may not be co-located with any other transmitter or antenna; The module shall be only used with the internal antenna(s) that has been originally tested and certified with this module. The antenna must be either permanently attached or employa ‘unique’ antenna coupler. As long as the conditions above are met, further transmitter test will not be required. However, the host manufacturer is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emis…
