This device complies with part 15 of the FCC Rules. 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. Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. 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 communications. 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 output on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. _________________________________________________________ www.btwtag.com 3 Ver. 2.0 Contents Description .............................................................................................................................................. 5 Getting Started ........................................................................................................................................ 6 Signing in ............................................................................................................................................. 6 Menu ...................................................................................................................................................... 7 Dashboard ........................................................................................................................................... 7 Today Balance ................................................................................................................................. 9 Active Tags ...................................................................................................................................... 9 Contacts Metrics ............................................................................................................................ 10 Real Time Areas ............................................................................................................................. 10 Real Time Gates ............................................................................................................................. 11 Last Activities ................................................................................................................................. 12 Latest Contact Events .................................................................................................................... 12 Contact Events................................................................................................................................... 12 Contact Tracing ................................................................................................................................. 14 People ................................................................................................................................................... 15 Man -Tags .......................................................................................................................................... 15 Device Configuration ..................................................................................................................... 16 Massive Configuration ................................................................................................................... 19 Creating a Group ........................................................................................................................... 21 Employees ......................................................................................................................................... 23 Environment ......................................................................................................................................... 26 Areas ................................................................................................................................................. 26 Gates ................................................................................................................................................. 29 btwTAG Configuration ........................................................................................................................... 32 Single btwTAGs .................................................................................................................................. 32 Multiple btwTAGs .............................................................................................................................. 40 Programmer Mode ............................................................................................................................ 41 Live Configuration ...................................…

Authorized Agent: Radiometrics Midwest Corporation (815) 293-0772 RF Exposure FCC ID: 2AWIV-20A061 1.0 INTRODUCTION These calculations are based on the highest average power from the EUT. The 915 MHz transmitter operates for 6.4 mSec every 528 mS for a duty cycle of 1.21%. The Wi-Fi Module will only be operated at a duty cycle of much less than 10% over any six-minute period. Therefore, 10 % was used in the calculations. For the d For all calculations 1 dB was added to the power for tune up tolerance. 2.0 FCC SAR TESTING EXCLUSION: In accordance with FCC KDB Publication 447498 D01 V05R02 Clause 4.3.1(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)]x[√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 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. This table is for devices with a separation less than 50 mm.
