HOMELINK Transceiver Won't Learn Remote Transmitter's Code (100100E)

HOMELINK TRANSCEIVER WON'T LEARN REMOTE TRANSMITTER'S CODE
TECHNICAL SERVICE BULLETIN

Service Information
To stretch battery life, many remote transmitters (we're talking about the ones used for controlling garage doors, lighting, or security gates-especially the ones you keep in your pocket) broadcast their codes for just 3 to 10 seconds when you push and hold their transmit button. Problem is, that's often not enough time for the HomeLink® transceiver to learn the code.
If the transceiver is having a tough time learning that transmitter's code, try pushing the transmit button again and again. This should give it enough time to learn the code.
