it is an emergency and requires immediate action.
Any interpreter or technician can press the “Wrong Channel” quick message button and a message will be transmitted in the chat that an interpreter is broadcasting on the wrong channel.
Another option is to tell your boothmate over InterStar ICP to change to the correct outgoing channel. Because it is going to be inside InterStar ICP only, the listeners will not hear that communication, however make sure that your microphone in the main event is muted.
