This device complies with Part 15 of the FCC rules and with Industry Canada licence-exempt RSS standard(s). 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. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploita- tion est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. 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 communi- cations. 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. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. Your device is a radio transmitter and receiver. It is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission of the U.S. Government.

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 Coach’s Unit. A headset, that only receives, 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 and 2.4 GHz ISM bands. The unit is battery powered. Zygo Radios The Zygo system coach’s unit has two radios, a Bluetooth radio, operating in the 2.4 GHz ISM band, and the low frequency transmitter to the headset, that operates in the 174-216 MHz band. The Bluetooth channel with the highest measured power is the low channel at 2402 MHz with a measured power of 11.0 mW (10.4 dBm). The low frequency radio channel with the highest measured power is its low channel at 176 MHz with a measured power of 67.3 mW (18.3 dBm). When used by a swimming coach the low frequency radio is a push-to-talk device. 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)] ꞏ [√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)ꞏ(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)ꞏ10]} 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: 푃ൌ푇∙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, 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 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 th…
