Abstract: An apparatus and method suitable for use as an electronic remote locating device. The method including synchronizing an unprogrammed receiver with a transmitter so that the unprogrammed receiver responds only to the transmitter. The transmitter continuously increments a storage element when electrical power is initially applied to the transmitter and halts incrementing of the storage element when a first event is detected. Next, the transmitter saves the value of the storage element in memory as the unique identification code. The transmitter then transmits the identification code for a first predetermined length of time at a preselected frequency. The receiver monitors the preselected frequency searching for a received identification code for a predetermined period of time after electrical power is applied to the receiver. The receiver then verifies the validity of the received identification code and determines whether a prior identification code exists in the memory of the receiver.
