For WT-D5800, the dynamic feedback control function can be set to be turned ON/OFF.
• When the setting is ON, the parameters for the FBS filter will be automatically set to control acoustic feedback
dynamically.
• When the setting is OFF, the parameters for the FBS filter will not be set automatically and the feedback will
not be controlled dynamically.
• When the function is turned from ON to OFF, or WT-D5800’s power is turned OFF, the filter generated
automatically during feedback detection with the dynamic mode will be cleared.
