Chamberlain LA412 - Manual (Page 34)

NOTES:
• The gate with the longer travel span (opening) must be set as the primary gate (GATE 1).
• If one gate is overlapping the other, the gate that is overlapping must be connected to GATE 1 so it will start moving before the other
gate; gate 2 may need to be closed fi rst if there is overlap or a gate lock is being used.
• The programming can be exited at any time by pressing the RESET button. Programming times-out automatically after 60 seconds of
inactivity.
