the power level at which your device transmits.
• This device meets the government’s requirements for exposure to radio waves.
• This device is designed and manufactured not to exceed the emission limits for exposure
to radio frequency (RF) energy set by the Federal Communications Commission of the
U.S. Government.
• This device complies with FCC radiation exposure limits set forth for an uncontrolled
environment. To ensure compliance with RF exposure guidelines the device must be used
with a minimum separation from the body listed in the table below. Failure to observe
these instructions could result in your RF exposure exceeding the relevant guideline limits.

FCC External antenna
Any optional external antenna used for this transmitter must be installed to provide a separation
distance of at least the minimum separation distance listed in the table above from all persons
and must not be co-located or operated in conjunction with any other antenna or transmitter.
Please consult the health and safety guide of the chosen antenna for specic body separation
guidelines as a greater distance of separation may be required for high-gain antennas.
Any external antenna gain must meet RF exposure and maximum radiated output power limits of
the applicable rule section. The maximum antenna gain for this device as reported to the FCC is:
