The two-way portable Wireless Audio Transceiver (WAT) WAT-01TW system consists of an audio transmitter and a set of receiver/transmitters. The guide can speak to the transmitter and visitors can hear from the receivers. When a visitor presses a button on the receiver, he can speak to the handset and all the others will hear him.
