If it's hiding nearby, such as under a cupboard or in the next room, you can easily followthe sound to find it. 3.2 Automatical ly restore connection af ter disconnection If the distance between the paired MyTag and the iOS device exceeds the Bluetooth connection distance (In the closed barrier-free space is 50m), when you click "Pl ay Sound" in the Fi nd My app, it will prompt that the connection cannot be made; If MyTag and the iOS device are in Bluetooth connection distance, click "Pl ay a Sound" in the Fi nd My app, it will play consecutive sounds, and you can find the items just following the sound. 3.3 Fi nd items with help fromhundreds of millions of friends. Fi nd My Network will help you find your belongi ngswhen they are left far behind, like at the beach or gym. As long as iOS device users allowFi nd My network access, MyTag will send out a secure Bluetooth signal that can be detected by nearby iOS devices in Fi nd My network, these devices send the location of your MyTag device to iCloud, then you can goto the Fi nd My app and see it on the map. The whole process is anonymous and encrypted to protect your privacy. And it’s efficient, so there is no need to worry about the battery life and data usage. 3.4 Lost Mode - Fi nd things eas ier Just like other Apple devices, MyTag can be put into Lost Mode. You'll automatically get a notification when it’s detected by other devices in the Fi nd My network. You can activate Lost Mode in Fi nd My app by following the onscreen instructions, adding your phone number or email account. Soif others pick up your MyTag,they c an knowmore info about it and know howto contact you by following the learning more pageinstruction in Fi nd My app . 3.5 Prevent unwanted trac king To prevent unwanted tracking,when someone else's MyTag device is mixed into your belongi ngs, your Apple device will find it and send you an alert notification. If you haven't found this device after a while, it will play a sound so you can find it. But don't worry, if someone next to you wearing a MyTag device, as long as the device does not leave the owner, you will not receive a notification. 3.6 Privac y protection Only you can see where your MyTag is. No location data or location history is physically stored inside MyTag. Communication with the Fi nd My network is end-to-end encrypted so that only the owner of a device has access to its location data, and no one, including Apple, knows the identity or location of any device that helped find it. 深圳瑞福来智能科技股份有限公司 Shenzhen Reflyi ng Electron ic Co.,Ltd FCC Cau tion This de vi ce compl ies with pa rt 15oftheFCCRul es.Ope rationis su bj ect to the fol lowingtwo conditions:(1)This de vi ce may notcauseha rmfulint erference, and(2) thi s de vi ce mustacceptany int erferenc e received,inc ludingint erference tha t may cause undesi red operation.

RF EXPOSURE EVALUATION METHOD FCC ID:A7M-0355474 Applicable standard： In accordance with FCC 47 CFR part 2 (2.1093) this device has been defined as a portable device which is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user. Portable devices must be evaluated using the specified in FCC 47 CFR part 2 (2.1093) and ANSI/IEEEC95.1-1992. and had been tested in accordance with the measurement methods and procedures specified in IEEE 1528-2003. Per FCC KDB 447498 D01 v06, the 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances s 50 mm are determined by: SAR Test Exclusion Thresholds for 100 MHz – 6 GHz and ≤ 50 mm Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. 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. BLE Modulation Test Channel Output Power (dBm) Limit (dBm) GFSK 1Mbps Low 3.96 30 GFSK 1Mbps Middle 3.57 30 GFSK 1Mbps High 3.21 30 GFSK 2Mbps Low 3.90 30 GFSK 2Mbps Middle 3.47 30 GFSK 2Mbps High 3.12 30 max possible output power (PK,conducted)：4±1dBm -6.02dBi logarithmic terms convert to numeric result is nearly 0.250 5dBm=3.16mW 2402MHz [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance,mm)] · [√f(GHz)]=3.16/5*√2.402 =0. 98≤3.0 2440MHz [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance,mm)] · [√f(GHz)]=3.16/5*√2.440=0.99≤3.0 2480MHz [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance,mm)] · [√f(GHz)]=3.16/5*√2.48=1.00≤3.0 Conclusion: 1. [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] * [√f(GHz)] < 3.0. 2. SAR Test Exclusion Thresholds is 3.0 for separation distance 5mm. Therefore, SAR test is not required.
