MPE Test Report Report No.: R1908A0493‐M1V1 4 Test Result According to section 1.1310 of FCC 47 CFR Part 1, limits for maximum permissible exposure (MPE) are as following Note1. Occupational/controlled limits apply in situations in which persons are exposed as a consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure. Limits for occupational/controlled exposure also apply in situations when an individual is transient through a location where occupational / controlled limits apply provided he or she is made aware of the potential for exposure. Note2: General population/uncontrolled exposures apply in situations in which the general public may be exposed, or in which persons that are exposed as a consequence of their employment may not be fully aware of the potential for exposure or can not exercise control over their exposure.

MPE Test Report Report No.: R1908A0493‐M1V1 RF Exposure Calculations: The following information provides the minimum separation distance for the highest gain antenna provided. This calculation is based on the conducted power, considering maximum power and antenna gain. The formula shown in KDB 447498 D01 is used in the calculation. Equation from KDB 447498 D01 General RF Exposure Guidance v06 (10/23/2015) is: 2 S= PG / 4∏R 2 Where: S = power density (in appropriate units, e.g. mW/cm ) P = Time-average maximum tune up procedure (in appropriate units, e.g., mW) G = the numeric gain of the antenna R = distance to the center of radiation of the antenna (20 cm = limit for MPE) Test Result Limit Value Band PG (mW) 2 2 Conclusion (mW/cm ) (mW/cm ) Zigbee 7.691 0.002 1.000 Pass Note: R = 20cm ∏= 3.1416 Note: For transmitters, minimum separation distance is 20cm, even if calculations indicate MPE distance is less.
