Abstract
A trainable transceiver for learning and transmitting an activation signal that includes an RF carrier frequency modulated with a code for remotely actuating a device, such as a garage door opener. The trainable transceiver includes a frequency table including a list of frequencies for remote transmitters known to transmit for only a short duration and the trainable transceiver first reads the short duration frequencies from the frequency table. The trainable transceiver may additionally include a prompting circuit for prompting an operator to cause a remote transmitter to retransmit its activation signal if the activation signal ceases before training is complete.
