Tour Guide System
Cordless tour-guide sets were, as the name suggests, designed for professional guiding on visits to factories, museums or tourist excursions, frequently associated with mobility of listeners and groups.
Nowadays they are also suited to use as whispering equipment for interpreters under certain circumstances. This usually means when it is not possible to set up standard interpretation booths and equipment, e.g. for lack of space. They are no substitute for regular interpretation equipment in large halls.
