5.2. Automatic Mic-Off Function
The automatic mic-off function automatically turns off the in-use microphone when a break in speech exceeds
30 seconds.
By using this function, the Delegate unit's microphone turns off after 30-second break even if a speaker forgets
to turn it off after use.
[Setting]
Set the Automatic mic-off setting switch to the ON (30 seconds of time out) position.
Tip
Set this switch to OFF if this function is unnecessary.
5.3. Test Function
The test function is especially useful to check operation of all connected conference units.
This function allows the microphones of all connected conference units to turn on. In this event, no sound is output
from their internal speakers, but audio signals are output from their Recording/Headphones output terminal.
All conference units can speak without operating the Talk key regardless of the Delegate unit ON/OFF switch setting.
[Setting]
Set the Test switch to the ON position.
Tip
After test completion, be sure to set this switch to OFF.
Notes
• 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.
