8.2. Automatic Mic-Off Function
Using the Automatic mic-off setting switch of the TS-770 Central Unit, the automatic mic-off function can be
set. Whenever a break in speech exceeds a specified period of time, the Central unit presumes speech
completion and automatically turns off the microphone. Delegate unit's microphone turns off after the preset
period of time even if a speaker forgets to turn it off after use.
The break time can be set for either 20 (20s position) or 40 (40s position) seconds. Set the switch to OFF if
this function is unnecessary.

8.3 All Mic-On Function
It is possible to turn on the microphones of all connected conference units by setting the Central unit's All Mic-
On switch to ON. In this event, no sound is output from Chairman and Delegate unit's internal speakers,
however audio signals are output from their Recording/Headphone Output terminals.
All conference units can speak at any time without requiring Talk key operation, regardless of the Speaker
Restriction function setting. The All Mic-On function is especially useful when wishing to record small
conferences or broadcast conference contents to other areas.
Note
When the All Mic-On function is enabled and it is desirable to have a remote party speak by way of the
Remote Delegate Interface unit, be sure to set the unit's Auto/Manual Selector switch to MANUAL. The party
cannot speak if the switch is set to AUTO.

Notes
• When the automatic mic-off function is selected, any break in speech exceeding the preset time during
speech will automatically turn off the microphone. Therefore, for conferences in which long breaks in speech
are expected, set the automatic mic-off setting switch to the OFF position.
• In areas with high levels of background noise, the Central unit may mistake the noise to be speech and the
automatic mic-off function will not operate correctly. In such cases, this function should be disabled by
placing the switch in the OFF position.
• In the system employing 2 or 3 Central units, it is not possible to operate the units with each different setting.
Perform the same setting for all connected Central units.
