ABSTRACT:
An apparatus for locating and recovering a misplaced remote unit includes a base unit including a radio frequency transmitter adapted to produce radio signals in response to a user command and a remote unit adapted to control at least one function of the base unit. The remote unit includes a radio frequency receiver adapted to receive the radio signals from the radio frequency transmitter, and an audio circuit adapted to produce audible musical signals as sensory input to the user in response to the received radio signals. The musical signals are capable of calming the user when the user is under stress such that location and recovery of the remote unit may be obtained.
