Abstract:
1. A method, comprising: receiving a sample signal using a receiving circuit of a transceiver, said sample signal having sample transmission values; comparing the sample transmission values of the sample signal to transmission values stored in a memory of the transceiver, said transmission values stored in the memory to correspond to a plurality of receivers; associating a first switch of the transceiver with a first set of transmission values and corresponding transmission frequency in memory for a first receiver of the plurality of receivers when the first set of transmission values stored in memory for the first receiver match the sample transmission values from the sample signal; retrieving, upon detecting a user selection of the first switch, the first set of transmission values and corresponding transmission frequency stored in memory for the first receiver, and causing a signal to be transmitted at a predetermined frequency, said signal capable of activating the first receiver; comparing an actual signal frequency for the signal, as received by the receiving circuit, to a reference frequency; and adjusting the predetermined frequency of the signal when the actual signal frequency and the reference frequency differ by other than a predetermined difference.
