* - Per Industry Canada Section 5.3 - The 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 3.5 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.
