TALKER DETECTION BACKWARD PROTECTION TIME SETTING
VOICE RELATED
SUMMARY: When automatically switching on detection of voice, protection time is set until 
the start of switching, after detection of voice, by recognizing that conference 
room in which  the voice was detected.
STEP PROCEDURE 
Note:
Set talker detection backward protection time with the factory shipment value (0BH
) as a 
general rule.  If change is...

TALKER DETECTION FORWARD PROTECTION TIME SETTING
VOICE RELATED
SUMMARY: When automatically switching on detection of voice, protection time is set until 
the start of detecting the voice of another talker after disappearance of the current 
voice signal.
STEP PROCEDURE 
Note:
Set talker detection forward protection time with the factory shipment value (0DH
) as a 
general rule.  If change is necessary for any reason, be...

TALKER DETECTION VOICE LEVEL SETTING
VOICE RELATED
SUMMARY: Set the threshold level for voice prominence decision when automatically 
switching on detection of voice.
STEP PROCEDURE 
Note:
Use as a general rule the factory shipment value (06H
) for the talker detection voice level.  
Adjust the detection level higher if required (if the conference room is noisy, etc.).  The 
parameter can be set for every connecting...
