Product Description The Swimmersive Zygo2 is a communication system for swimmers and swimming coaches. The Zygo2 system has 2 components. A transmitter to stream music to swimmers or for a coach to talk to his swimmers, called the Zygo Underwater Communication Radio Transmitter (Zygo transmitter or transmitter). A headset, worn by the swimmers, called the Zygo Underwater Communication Radio Headset. It’s primary use is to stream music to swimmers as they work out. It also allows a coach to give instructions to swimmers as they work out. The Zygo transmitter operates in the 174-216 MHz VHF band and 2.4 GHz ISM bands. The unit is battery powered. Zygo Radios The Zygo transmitter has two radios, a Bluetooth radio, operating in the 2.4 GHz ISM band, and the VHF transmitter to the headset, that operates in the 174-216 MHz band. For the Bluetooth radio the measured powers were: Frequency (MHz) Power (dBm) 2402 6.41 2441 6.21 2480 6.46 The Bluetooth channel with the highest measured power is the high channel at 2480 MHz with a measured power of 4.43 mW (6.46 dBm). The low frequency transmitter measured powers were: Frequency (MHz) Power (dBm) 175.0 18.861 194.5 11.328 209.5 10.785 The low frequency radio channel with the highest measured power is its low channel at 175.0 MHz with a measured power of 76.93 mW (18.861 dBm). The low frequency radio has a duty cycle of transmission for 3.4 mS followed by a 1.0 mS off time. This calculates to a duty cycle of 5.3 dB. FCC Requirements FCC KDB 447498 D01 V06 section 4.3 gives SAR test exclusion guidance: 4.3. General SAR test exclusion guidance 4.3.1. Standalone SAR test exclusion considerations .... a) For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(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, 30 where • f (GHz) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation 31 • The result is rounded to one decimal place for comparison • The values 3.0 and 7.5 are referred to as numeric thresholds in step b) below 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 according to 4.1 f) is applied to determine SAR test exclusion. b) For 100 MHz to 6 GHz and test separation distances > 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following (also illustrated in Appendix B): 1) {[Power allowed at numeric threshold for 50 mm in step a)] + [(test separation distance – 50 mm)·(f(MHz)/150)]} mW, for 100 MHz to 1500 MHz 2) {[Power allowed at numeric threshold for 50 mm in step a)] + [(test separation distance – 50 mm)·10]} mW, for > 1500 MHz and ≤ 6 GHz The formula can be used to calculate the maximum allowable power. The power of interest is the source-based time-averaged maximum conducted output power of the RF channel. The formula for the maximum allowable power, based on the guidance of section 4.3 in the KDB, is: 푃=푇∙퐷/√푓 • P is the source based time-averaged maximum conducted output power in mW • T is the numeric thresholds of 3.0 and 7.5 • D is the minimum separation distance in m • f is the RF channel transmit frequency in GHz For the highest frequency used, 216 MHz: For the highest frequency used, 2.48 GHz: • for a numeric threshold of 3.0 the maximum power is 9.6 mW • for a numeric threshold of 7.5 the maximum power is 23.8 mW ISED Canada Requirements Canadian regulation for RF exposure are contained in Spectrum Management and Telecommunications Radio Standards Specification RSS-102 Issue 5, March 2015, Radio Frequency (RF) Exposure Compliance of Radiocommunication Apparatus (All Frequency • for a numeric threshold of 3.0 the maximum power is 32.3 mW • for a numeric threshold of 7.5 the m…

Hermosa Beach, CA 90254 By TEM Consulting, LP 140 River Rd. Georgetown, TX 78628 September 2024 The Zygo Transmitter has two antennas. One is for its VHF radio. The second is for its BLE radio. The VHF antenna is a “Meandered Dipole.” See Figure 1 and Figure 2. The Bluetooth LE (BLE) is a “PIFA” trace on the main PCBA. See Figure 3. The peak gain by tested channel for the Zygo Transmitter VHF antenna is in Table 1. The peak gain for the Zygo Transmitter BLE antenna is + 3.07 dBi. See Table 2.
