Note 1: Per Industry Canada Section 5.3 - The rated output power of this equipment is for single
carrier operation. For situations where multiple carrier signals are present, the rating would have
to be reduced by 3.5 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.
