A trainable transmitter includes a receiver circuit and a control circuit. The receiver circuit is configured to receive signals. The control circuit is coupled to the receiver circuit and is configured to determine a noise level for a frequency range of the receiver circuit. The control circuit is further configured to select and provide a receiver threshold to the receiver circuit. The receiver threshold is variable based on the noise level. The trainable transmitter may be integrated in a vehicle, in particular a vehicle interior element.
