INSIDE THE BOX - 1 x Earbud Unit - AKT1 Challenge Coin - 3 Pairs of Foam Eartips (S,M,L) - Type-C USB Charging Cable - Cable Cinch - User Manual - 3 Pairs of Silicone Eartips (S,M,L) - Carry Case The AKT1 StrikePRO HTBT earbuds operate differently than typical BT earbuds or earplugs, and especially different from earbuds for music listening and entertainment. They are first of all hearing protection devices with the primary function of protecting you from hearing loss. The hearing augmentation is state of the art digital sound enhancement with the result of very natural hear through capabilities, allowing you to maintain not only more accurate situational awareness, but increased awareness and focus on the task at hand. The BT functionality is State of the Art using BT 5.0 with better connectivity, a wider band for music listening and Qualcomm CVC noise cancellation. During phone calls, you will note better voice recognition, and more accurate sound recreation. For music listening, you will note that the latest BT version enhances clarity and bandwidth significantly. The combination of sound isolation from environmental noise and absolute design control of the bud itself with acoustics in mind with every design decision. We sincerely built these with the user in mind and made every decision without compromise. We think you will find that to be evident in use. Team AKT1 Sport www.AKT1sport.com FCC STATEMENT 1.

FCC ID: 2A5PL-STRIKEPROHTBT Portable device According to §15.247(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 V06 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: Transmit Frequency (GHz) Mode Max Conducted Power (dBm) tune up maximum power(dBm) Result calculation 1-g SAR 2.402 GFSK -4.22 -4 0.12 3 2.441 GFSK -2.65 -2 0.20 3 2.480 GFSK -1.46 -1 0.25 3 2.402 PI/4 DQPSK -3.27 -3 0.16 3 2.441 PI/4 DQPSK -1.69 -1 0.25 3 2.480 PI/4 DQPSK -0.53 0 0.31 3 2.402 8DPSK -3.00 -3 0.16 3 2.441 8DPSK -1.40 -1 0.25 3 2.480 8DPSK -0.26 0 0.31 3 Conclusion: For the max result : 0.31≤ 3.0 for 1-g SAR extremity SAR, No SAR is required.
