Sennheiser TourGuide is a short range, battery powered radio system which transmits an audio message from presenter to listener. TourGuide uses a radio microphone for the presenter, and personal ultra-light receivers for each listener. It is completely portable so parties can stop or move around at will. Pre-recorded messages can be transmitted instead of your own "live" message, and you can move from one source to the other.

If you can switch on and listen to a portable radio, you can use TourGuide! You switch on the transmitter, ask your listeners to switch on their receivers, adjust their volume to suit - and then start speaking into the microphone.
