These limits are designed to provide reasonable protection against harmful inte rference in a residential installation. This equipment generates uses and can radiate radio frequency energy a nd, if not installed and used in accordance with the instructions, may cause harmful interference to radio com munications. 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 turn ing 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 important announcement Important Note: Radiation Exposure Statement 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: 1. The antenna must be installed such that 20 cm is maintained between the antenna and users, and 2. The transmitter module may not be co-located with any other transmitter or antenna, 3. For all products market in US, OEM has to limit the operation channels in NFCby supplied firmware programming tool. OEM shall not supply any tool or info to the end- userregarding to Regulatory Domain change. As long as the three 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. Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01r01 2.2 List of applicable FCC rules CFR 47 FCC Part 15 Subpart C has been investigated. It is applicable to the modular transmitter. 2.3 Specific Operational Use Conditions - Antenna Placement Within the Host Platform The module is tested for standalone mobile RF exposure use condition. ● The antenna must be installed such that 20cm is maintained between the antenna and users ● The transmitter module may not be co-located with any other transmitter or antenna. 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. 2.4 Limited Module Procedures Not applicable 2.5 Trace Antenna Designs Not applicable 2.6 RF Exposure Considerations This device complies with FCC radiation exposure limits set forth for an uncontrolled environment.
