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.
