5.1 FCC Notice 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 the receiver. - Connect the equipment to 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. 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 of the device. Any changes or modifications in construction of this device which are not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

6.1 Industry Canada Statement This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canada’s licence-exempt RSS(s). Operation is subject to the following two conditions: (1) This device may not cause interference. (2) This device must accept any interference, including interference that may cause undesired operation of the device. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) L'appareil ne doit pas produire de brouillage, et (2) L'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. Please notice that if the IC 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 IC : 2703N-LCB003” any similar wording that expresses the same meaning may be used. L’étiquette d’homologation d’un module d’Innovation, Sciences et Développement économique Canada devra être posée sur le produit hôte à un endroit bien en vue, en tout temps. En l’absence d’étiquette, le produit hôte doit porter une étiquette sur laquelle figure le numéro d’homologation du module d’Innovation, Sciences et Développement économique Canada, précédé du mot « contient », ou d’une formulation similaire allant dans le même sens et qui va comme suit : Contient IC : 2703N-LCB003 est le numéro d’homologation du mo Bluetooth module specifications Model LCB-003 Frequency Range 2402 MHz - 2480 MHz EIRP (Max) 7.07 dBm Antenna Gain 2.76 dBi

1. Applicable FCC Rules a. CFR 47 Part 15.247 2. Operational Condition The module is limited to OEM installation ONLY. The OEM integrator is responsible for ensuring that the end-user has no manual instruction to remove or install module. A separate approval is required for all other operating configurations, including portable configurations with respect to Part 2.1093, Part 15 Subpart B, and difference antenna configurations. 3. Limited Module Procedure: N/A 4. Trace antenna designs: N/A 5. RF Exposure consideration This modular complies FCC/ISED RF exposure requirement at 15 mm distance. Any host equipment that has separation distance less than 15 mm shall require additional RF exposure assessment. 6. Antennas This modular has PCB pattern antenna. Any changes of antenna designs might require additional assessment. Antenna type shall be same type and antenna gain shall be less or equal to certified antenna. 7. Label and compliance information The end user manual shall include all required regulatory information/warning as shown in this manual. 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 FCC ID : BEJ-LCB003” any similar wording that expresses the same meaning may be used. 8. Information on test modes and additional testing requirements This modular was tested in standalone configuration. Integration of this modular into a host equipment would require additional testing.

9. Additional testing, Part 15 Subpart B disclaimer The grantee should include a statement that the modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules) listed 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. If the grantee markets their product as being Part 15 Subpart B compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.
