RF Exposure / SAR statement
Applicant: Chamberlain Group Inc.
Model: NLS1, Portable Wireless Intercom


Calculations:

The following information provides the minimum separation distance for the highest gain
antenna provided with the “NLS1” as calculated from FCC OET Bulleting 65 Appendix
A, Table (B) Limits for General Population / Uncontrolled Exposure. This calculation is
based on the highest EIRP possible from the system, considering maximum power and
antenna gain, and considering a f/1500mW/cm2 (0.601mW/cm2) uncontrolled exposure
limit. The Friis formula used was:

       P *G
S=
     4 *π * r 2

Where
        P = 54.45mW (Maximum Peak Output Power)
        G = 3.27 (Numerical Antenna Gain, 5.14dBi)
        R = 20.0cm

For NLS1 the S = 0.0354mW/cm2
