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. Caution: Any changes or modifications to this device not explicitly approved by manufacturer could void your authority to operate this equipment. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Country Code selection feature to be disabled for products marketed to the US/Canada. This device is intended only for OEM integrators under the following conditions: The antenna must be installed such that 20 cm is maintained between the antenna and users, and The transmitter module may not be co-located with any other transmitter or antenna, As long as the two conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed. Important Note: In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End Product Labeling The final end product must be labeled in a visible area with the following: Contains FCC ID: 2BQYGCTCCMGM240PFC Integration instructions ========================= Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01 **2.1 List of applicable FCC rules** CFR 47 FCC PART 15 SUBPART C has been investigated. It is applicable to the modular transmitter **2.2 Specific operational use conditions** This module is stand-alone modular. If the end product will involve the Multiple simultaneously transmitting condition or different operational conditions for a stand-alone modular transmitter in a host, host manufacturer have to consult with module manufacturer for the installation method in end system. **2.3 Limited module procedures** Not applicable **2.4 Trace antenna designs** Not applicable **2.5 RF exposure considerations** This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. **2.6 Antennas** This radio transmitter FCCID: 2BQYGCTCCMGM240PFC has been approved by Federal Communications Commission to operate with the antenna types listed below, with the maximum permissible gain indicated. Antenna types not included in this list that have a gain greater than the maximum gain indicated for any type listed are strictly prohibited for use with this device. .. list-table:: :widths: 25 25 25 25 :header-rows: 1 * - Antenna No. - Operate Frequency Band - Antenna Type - Maximum Antenna Gain * - AGP-I240501SMR - 2400-2500 MHz - Dipole Antenna - 2.48 dBi * - GW.51.5153 - 2400-2500 MHz - Dipole Antenna - 5.23 dBi **2.7 Label and compliance information** The final end product must be labeled in a visible area with the following" Contains FCCID: 2BQYGCTCCMGM240PFC" **2.8 Information on test modes and additional testing requirements** Host manufacturer is strongly recommended to confirm compliance with FCC requirements for the transmitter when the module is installedin the host. **2.9 Additional testing, Part 15 Subpart B disclaimer** Host manufacturer is responsible for compliance of the host system with module installed with all other applicable requirements for the system such as Part 15 B.    **2.10 Note EMI Considerations** Host manufacture is recommended to use D04 Module Integration Guide recommending as "best practice" RF design engineering testing and evaluation in case non-linear interactions generate additional non-compliant limits due to module placement to host components or properties. **2.11 How to make changes** This module is stand-alone modular. If the end product will involve the Multiple simultaneously transmitting condition or different operational conditions for a stand-alone modular transmitter in a host, host manufacturer have to consult with module manufacturer for the installation method in end system. According to the KDB 996369 D02 Q&A Q12, that a host manufacture only needs to do an evaluation (i.e., no C2PC required when no emission exceeds the limit of any individual device (including unintentional radiators) as a composite. The host manufacturer must fix any failure.
