FCC Warning: 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. -- Consult the dealer or an experienced radio/TV technician for help. RF Exposure Statement To maintain compliance with FCC’s RF Exposure guidelines, This equipment should be installed and operated with minimum distance between 20cm the radiator your body: Use only the supplied antenna. -- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. 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.

FCC ID: OKUTSB65528 Portable device According to §15.247(e)(i) and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to KDB447498 D01 General RF Exposure Guidance V05 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] * [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where f(GHz) is the RF channel transmit frequency in GHz； Power and distance are rounded to the nearest mW and mm before calculation； The result is rounded to one decimal place for comparison； The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. We use 5mm as separation distance to calculate. Maximum measured transmitter power: Bluetooth: Transmit Frequency (GHz) Mode Measured Power (dBm) Tune-up power (dBm) Max tune-up power(dBm) Result calculation 1-g SAR 2.402 GFSK 3.35 4±1 5 0.9802 3.0 2.441 GFSK 4.11 4±1 5 0.9881 3.0 2.480 GFSK 4.27 4±1 5 0.9960 3.0 2.402 π/4-DQPSK 2.20 2±1 3 0.6185 3.0 2.441 π/4-DQPSK 2.68 2±1 3 0.6235 3.0 2.480 π/4-DQPSK 2.53 2±1 3 0.6284 3.0 2.402 8DPSK 2.43 2±1 3 0.6185 3.0 2.441 8DPSK 2.98 2±1 3 0.6235 3.0 2.480 8DPSK 2.84 2±1 3 0.6284 3.0 Conclusion: For the max result : 0.9960≤ 3.0 for 1-g SAR extremity SAR, No SAR is required.
