ADCP-75-187 • Preliminary Issue 1B • November 2005 • Section 2: DESCRIPTIONPage 2-20© 2005, ADC Telecommunications, Inc.Note 1: Per Industry Canada Section 5.3 - The rated output power of this equipment is for singlecarrier operation. For situations where multiple carrier signals are present, the rating would haveto be reduced by 3.5 dB, especially where the output signal is re-radiated and can causeinterference to adjacent band users. This power reduction is to be by means of input power orgain reduction and not by an attenuator at the output of the device.
