Product Description The Swimmersive Zygo is a communication system for swimmers and swimming coaches. The Zygo system has 2 components. A transmitter to stream music to swimmers or for a coach to talk to his swimmers, called the Zygo Transmitter. A headset, worn by the swimmers, called the Zygo 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. When coach’s use the unit to give instructions the unit operates push-to-talk (PTT) and the Bluetooth link is not active. In this mode the unit is handheld. The Zygo transmitter operates in the 174-216 MHz VHF band and 2.4 GHz ISM bands. The Zygo headset operates in the 174-216 MHz. The unit is battery powered. Zygo Radios The Zygo system headset has a low frequency transmitter, that operates in the 174-216 MHz band. The measured powers were: Frequency (MHz) Power (dBm) 175.0 15.736 194.5 15.314 209.5 14.565 The highest measured power was with the low frequency radio channel. The low channel is at 175.0 MHz with a measured power of 37.46 mW (15.736 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 calculation31 • 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 W • 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 a numeric threshold of 3.0 the maximum power is 32.3 mW • for a numeric threshold of 7.5 the maximum power is 80.7 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 Bands). Section 2.5.1, Exemption Limits for Routine Evaluation – SAR Evaluation, provides the following exclusion limits: The values listed are for a 1 gram tissue value. If a device is worn on a limb and subject to the 10 gram value the values in the table are multiplied by 2.5: For limb-worn devices where the 10 gram value applies, the exemption limits for routine evaluation in Table 1 are multiplied by a factor of 2.5. Hence for the headset the limit is 71 mW. Product Analysis VHF Radio The low frequency radio has a 5.3 dB duty cycle It meets both the FCC and ISED test exclusion criterion. Conclusion This analysis concludes that the radio in the Zygo2H head…
