RF Exposure Evaluation
Limit
The criteria listed in the following table shall be used to evaluate the environment impact of human
exposure to radio frequency (RF) radiation as specified in 1.1310 & 2.1091

(B) Limits for General Population/Uncontrolled Exposure
0.3–1.34 614 1.63 *(100) 30

1500–100,000 - - 1.0 30
Note: f = frequency in MHz

Evaluation Method
Transmission formula: Pd = (Pout*G)/(4*pi*R2)
Where
Pd = power density in mW/cm2, Pout = output power to antenna in mW, G = gain of antenna in
linear scale;
Pi = 3.1416, R = distance between observation point and center of the radiator in cm

Remark:
1. Output power including tune up tolerance;
2. The maximum antenna gain is 3dBi
3. The exposure safety distance is 20cm.

Conclusion
The measurement results comply with the FCC Limit per 47 CFR 1.1310 & 2.1091 for the
uncontrolled RF Exposure and MPE complicance per KDB 447498 v06.
