The Master Controller Device contains a master processor that controls a GPS receiver, an RF (radio frequency) transmitter, digital memory storage, visual display, rechargeable power supply and a keypad used to access databases of locations, audio commentary lists, safety message file names and menu options within the master controllers digital memory storage and set the instruction parameters that the Master Controller Device processor instructs the RF Transmitter to broadcast as a short burst of encoded instruction packets to the Personal Wireless Receiver Devices that contain an RF receiver, RF receiver master processor, visual display, digital memory storage, rechargeable power supply, digital audio processor with analogue output and a keypad used to access data stored on the digital memory storage including a database of tour options, a database of language options and a database of digital audio files pertaining to each tour option and language option. Upon receiving an encoded instruction to play a digital audio file the Personal Wireless Receiver Device master processor verifies the language and tour pre-set on the Personal Wireless Receiver Device and then locates the digital audio file specified by the file name in the encoded instruction from the database of files stored in the Personal Wireless Receiver Device internal memory and sends that digital audio file to the Personal Wireless Receiver Device digital audio processor where it is converted to an analogue audio signal which is output to the headphone connector into which a set of headphones are plugged. This arrangement enables the participants of a group tour wearing the Personal Wireless Receiver Devices to hear the audio commentary in their selected language option.
