Once the parameter is flashing, use the UP and DOWN buttons to adjust the parameter value. The parameter is instantly updated while it is being adjusted - you should hear changes as the parameter is changing. RS-232 control strings are also sent via the RS-232 port so your remote control device is instanta- neously updated as well.

If the reflected signal picked up by the microphone is higher than the level of the signal sent to the line output to your amplifier, that microphone channel has positive room gain. The more positive the room gain, the harder the AEC must work to determine which signal is an echo and which is a local speech signal INDEX Mic/Line Inputs, Line Inputs, Line Outputs Page Page Phone 800 932-2774, 404 Polycom, Inc Installed Voice Business Group1725-80098-001-C 1720 Peachtree Street NW, Suite 220 Atlanta, GA
