The complete set consists of two microphone units and an additional Bluetooth headset, providing double protection for staff and customers. If the headset battery runs out, the VoiceBridge microphone unit attached to the protective wall automatically takes over. The headset and microphone unit are paired at delivery and can be expanded to accommodate up to 8 headsets. Stay in contact with customers within a radius of 5-10 meters. The device and headset can be easily cleaned with surface cleaner or additional hygiene covers can be ordered. The personnel microphone unit is activated as soon as the headset is empty or switched off, eliminating the need for time-consuming training of personnel.
