Programming the Transmitter
NOTES:
• The system accepts up to three transmitters.
• Entering the programming mode cancels all learned
transmitter codes, so none of the previously
programmed transmitters will work. You must
reprogram all of the transmitters once you are in the
programming mode.
• You must perform each of the first twelve steps
within 5 seconds of each other to enter programming
mode. Programming each transmitter (step 13) must
be done within 10 seconds.
