Step 4. Turn on the same number of microphones on the Conference units as the maximum number of open
microphones set at the Central unit. Speaking into the microphone, adjust the Central unit's Speech
volume control to an appropriate level.
Step 5. Initiate speech from the microphones of all Conference units, and confirm that acoustic feedback is not
produced.
If feedback occurs, widen the distance between the Chairman unit and the Delegate unit or reduce the
output volume to prevent feedback.
When feedback still remains, use the FBS function built in the Central unit, or an external graphic
equalizer to suppress it. (Refer to p. 50 "IF ACOUSTIC FEEDBACK OCCURS.")
