A system for locating an object, particularly a remote control, has a transmitter and a receiver, wherein the receiver has circuitry implementing power saving features. The receiver includes circuitry for turning off portions of the circuitry not essential for performing the current task. The receiver additionally only activates the wireless signal receiver portion of the circuitry periodically for short periods of time. The time of activation represents a small fraction of the operational time if the wireless signal receiver portion were to remain activated continuously.

A method of conserving power within a receiver, used in conjunction with a transmitter for generating a transmit signal, for locating a lost object, where said receiver comprises; a control circuit, a wake up timer circuit, a wireless signal receiver circuit and an audible signal generator circuit comprising the steps of: generating a periodic wake up signal using the wake up timing circuit; activating the wireless signal receiver circuit in response to receipt of said wake up signal by said control circuit for a set period of time to detect the presence of the transmit signal from the transmitter; generating a detect signal when the presence of the transmit signal is detected; activating the audible signal generator circuit upon receipt of said detect signal by said control circuit and disabling the wake up timer circuit and the wireless signal receiver circuit; and deactivating, after a preset period of time, the audible signal generator circuit, and enabling the wake up timer circuit and the wireless signal receiver circuit.
