The FCC requires that the following statement be included in this
manual:
This device complies with FCC radiation exposure limits as set forth for
an uncontrolled environment. This device should be installed and
operated so that its antenna(s) are not co-located or operating in
conjunction with any other antenna or transmitter. A separation
distance of at least 20 cm (8 inches) must be maintained to comply with
the FCC Radio Frequency Maximum Permissible Exposure (MPE)
requirements.
