Each headset and microphone unit comes with a windscreen. Windscreens reduce breathing and other
background noises that can make it hard for the terminal to understand what an operator is saying. For more
information about windscreen care and maintenance, see the Procedures section below.
Note: Vocollect strongly recommends that operators do not share headsets. Assigning one
headset to each operator reduces the likelihood that germs will pass between operators.
