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. 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 correct the interference by one or more of the following measures: R eorient the receiving antenna. I ncrease the separation between the equipment and receiver. Connect the equipment into and outlet on a circuit different from that to which the receiver is connected. C onsult the dealer or an experienced radio/TV technician for help. Chan ges or modifications not expressly approved by the party responsible for compliance could void your authority to operate the equipment. FCC ID:2AMQ6-F10PRO

When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion Page 2 of 2 1.2 EUT RF EXPOSURE EVALUATION Operational Mode: EDR （8-DPSK worst case） Channel Maximum Peak Conducted Output Power (dBm) Tune up tolerance (dB) Maximum tune-up Power(dB m) Maximum tune-up Power(mW ) Calculated value Exclusion threshold 2402MHz 0.91 ±1 1.91 1.55 0.48 3 2441MHz 0.58 ±1 1.58 1.44 0.45 3 2480MHz 0.65 ±1 1.65 1.46 0.46 3 Conclusion: the calculated value ≤3.0, SAR is exempted.
