* The manufacturer’s rated output power of this equipment is for single carrier operation. For situations
when multiple carrier signals are present, the rating would have to be reduced by 3 dB, especially
where the output signal is re-radiated and can cause interference to adjacent band users. This power
reduction is to be by means of input power or gain reduction and not by an attenuator at the output of
the device.
