Flexible Operating Modes

  • Standard Toggle Mode: Standard press-on/press-off operation, ideal for general conferencing applications.
  • Auto-On Startup Mode: Device powers on in the "Open" state automatically; press the button to switch the microphone off.
  • Push-to-Talk (PTT): Microphone is active only while the button is held down and mutes immediately upon release.
  • Push-to-Mute (PTM): Microphone remains active by default; pressing and holding the button silences the output for private asides.
  • Remote Control Mode: Allows for external triggering via network protocols or central control systems, with fully customizable logic.
