Abstract
A method and system of establishing a wireless network for audio data transmission with a first and second audio devices having first and second transceivers, the first audio device being an audio signal transmission unit with a user operable switch, and the first and second audio devices being assistive listening devices. Periodically the second transceiver listens for pairing information, at at least one public frequency channel; operating the switch by the user to initiate pairing at any time during operation of the first audio device; the first transceiver transmitting pairing information at said at least one public frequency channel upon operation of the switch. The second audio device automatically pairs to the first audio device upon reception of pairing information from the first transceiver. The first and second transceivers are controlled so that reception of the pairing information from the first audio device is accepted by the second audio device.
