Three selectable microphone modes are available for delegate discussion:

OPEN - allows to select the number of delegate microphones from 1 to 4 which can be simultaneously active. The delegate microphones more than the preset number cannot be activated and are unable to register a request to speak.

FIFO - allows to select the number of delegate microphones from 1 to 4 which can be simultaneously active. On a FIFO (first in first out) basis, any delegate can override another delegate simply by activating the microphone, but cannot override the chairperson.

OPERATOR - allows to select the number of delegate microphones from 1 to 4 which can be simultaneously active. Up to 8 delegates more than the preset number can register a request and wait to speak, and can be switched off manually to cancel the request.
