Manual Part 2

Precautions
The radiated output power of this device is below the FCC radio frequency
exposure limits based on that human proximity to the antenna shall not be less
than 20cm during normal operation.
IC notice
To reduce potential radio interference to other users, the antenna type and its
gain should be so chosen that the equivalent isotropically radiated power
(e.i.r.p.) is not more than that permitted for successful communication.
