                                           RF EXPOSURE

The subjest device is a Low Power Device Transmitter and is subject to FCC radiation limits in
15.231(e) and IC limits in RSS—210, Sec. 6.1.1. At the frequency of operation of 315 MHz, the
maximum allowed field at 3 meters, for both FCC and IC, is 67.7 dBuV/m. This corresponds to
an EIPR of —27.5 dBm or 0.002 mW.

Assuming a model of apoint source radiator, the power density would be 0.0006 mW/cm2 at 0.5
cm distance, a distance that is well inside the plastic case of the device.

FCC
This estimate definitely meets the FCC guideline of 1 mW/cm2.

IC
Since the radiated power is less than 200 mW, the device is exempt from RF Exposure regulations
(RSS—102, 4.2).
