A trainable transceiver for controlling a remote device includes a transceiver circuit, a user input device, and a control circuit. The transceiver circuit is configured to receive a first activation signal from an original transmitter and configured to transmit a second activation signal. The control circuit is coupled to the transceiver circuit and the user input device. The control circuit is configured to format and transmit the second activation signal, based on the first activation signal, in response to a user input received at the user input device. The control circuit is configured to reduce a duty cycle of the second activation signal relative to the first activation signal and increase a radio frequency power of the second activation signal relative to the first activation signal, while maintaining, for the second activation signal, an average radio frequency power over a predetermined amount of time below a predetermined limit. |
