The T4 IFB transmitter is FCC type accepted under Part 74:470 -
608MHz and 944.1 - 951.9 MHz
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 20cm (8 inches) must be maintained to comply
with
the FCC Radio Frequency Maximum Permissible Exposure (MPE)
requirements. |
