It advertises data in a Minew-defined format. Featuring 2-meter safe social distancing alarm and USB direct charging, the tag supports data interaction with MWristband APP. 3.Features Introduction Proximity Alerts When tag wearer A is within 2-meter of wearer B, it is an alarm distance. The wristbands of both wearer A and B will vibrate, and red lights flash. Store Contact Information Enable data storage function of B8 wristband through Demo APP. When tag A detects tag B within 2-meter, tag A will automatically store the ID and contact dates of tag B, and vice versa. If more tags come within a 2-meter range, tag A will automatically store the contact information of all other tags. 4.Turn On/Off Turn On: Press the Touch Button until the blue indicator light flash, meaning the device is activated. Turn Off: The tag can not be turned off via the Touch Button. Users can turn it off via APP.

Standalone SAR test exclusion considerations Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Exclusion Threshold condition, listed below, is satisfied. 4.1.2 Limits 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 17 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 Shenzhen Huaxia Testing Technology Co., Ltd Report No.: CQASZ20200700754E-02 Page: 6 of 6 4.1.3EUT RF Exposure 1) For BLE Measurement Data GFSK mode Test channelPeak Output Power (dBm) Tune up tolerance (dBm) Maximum tune-up Power (dBm)(mW) Lowest(2402MHz)3.553.0±14.02.512 Middle (2440MHz)3.392.5±…
