you will also have to synchronize the garage
door system with the integrated garage door
opener in the rear-view mirror. To do this you
will need to use the programming button on
the door drive control panel. The program-
ming button may be positioned in different
places depending on the manufacturer. It is
usually located on the door drive unit on the
garage ceiling.

drive operating instructions, e.g. under "Pro-
gramming of additional remote controls",

Notes on programming the remote con-
trol
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals after broadcasting for a few seconds.
Therefore, these signals may not last long
enough for the integrated garage door
opener. The signal is not recognized during
programming. Comparable with Canadian
law, some U.S. garage door openers also fea-
ture a "break".
