"CAUTION: Exposure to Radio Frequency Radiation.
Antenna shall be mounted in such a manner to minimize the potential for human
contact during normal operation. The antenna should not be contacted during
operation to avoid the possiblility of exceeding the FCC radio frequency exposure
limit. The minimum separation distance of 20cm from the antenna to the body of
user required."
