Using the Multifunction / Audio Priority switch

If you have an auxiliary audio device connected to your headset (i.e. music player, mobile phone or GPS), you can decide how you want to hear that audio when intercom audio is present. This ensures you do not miss important information being communicated on the intercom.

Use the switch on the headset control module to select an audio priority mode:

Switch positions

Switch settings take effect after the headset has been powered on for 24 seconds.
  • Top position (Mute): When intercom audio is present, other auxiliary audio is muted until the intercom audio stops
  • Middle position (Mix): Intercom audio is heard at the same time as audio from an auxiliary audio device
  • Bottom position (Off): Only intercom audio is preset; auxiliary audio is muted
