The PR-75a personal receiver is simple to use, reliable, and affordable. This unique receiver will automatically turn itself on and initiate its AutoSmart-Tuning process when the earphone is plugged in. The PR-75 receiver selects the closest appropriate transmitter in its vicinity and then sets itself to this channel. A convenient, one-button tuning control will cause the PR-75 to reinitiate the AutoSmart-Tuning process allowing the receiver to re-tune to a different compatible transmitter at venues where multiple transmitters are in use.
