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
first 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.
Close the gate.
