    For Canadian users, during the programming the customers hand-held transmitter may automatically stop programming after 1 or 2 seconds. This may not be long enough to program the HomeLink™ transmitter. If you are programming with one of these transmitters, the light on the HomeLink™ transmitter may prompt you to reactivate the hand-held transmitter with a series of double flashes. After the hand-held transmitter reactivates, the light on the HomeLink™ transmitter will flash rapidly. The flashing indicates that the transmitter has been successfully programmed. If the light returns to a slow flash, reactivate the hand-held transmitter until the light flashes rapidly.

  9. If the light does not perform as indicated, or the opener does not function properly, Refer to Garage Door Opener System Check .
