The stethoset receiver automatically deactivates itself the moment that it is taken off, meaning battery life will be preserved. No longer will the tourguide need to check all of the sets after one tour finishes and before the next tour starts. Your tour participants will be able to individually adjust the volume through a rotary control on the receiver, without the need to even take the device off. An LC display will clearly confirm the volume, battery status, quality of reception and the channel being listened to. Channels can easily be set and adjusted by using the middle buttons.
The reception range is about 100 m if your tour is outdoors and about 50 m if your tour is indoors.
