• The “FiFo” operating mode is selected with the button combination “Free” and “Requ” . Both LEDs of the
“Free” + “Requ” buttons will illuminate.
• When another microphone unit is activated, the microphone unit of the current speaker is deactivated. The limit in this
operating mode is 01.
• In the standard setting this function also refers to the chairman microphone unit. If the chairman microphone unit
is to be excluded partly or completely from this function, the values of this function have to be set to 00 in the
programming mode (refer to chapter 3.3.8 “Programming mode”). In the standard setting both functions are set
to 01.

released.

the button again) or “Auto-OFF” (after a pause of approx. 2 seconds the microphone is automatically turned off).
Furthermore, the “Prior” button can be linked with the microphone button to activate the priority function also

3.3.5 How to adjust the limit • With the “Limit” buttons you can determine the number of speakers, who are allowed to speak simultaneously
(“Free” and “Voice” mode) or who may enter a request-to-speak (“Request” mode). This option can be used for
all three operating modes.
