4.4 Travel Setting (Limit Switch Adjustment)
The SW300DC uses an electromechanical limit switch system. Before operating the gate opener for the first time, it is essential to complete the travel setting procedure.

Incorrect travel settings can lead to improper operation or damage.

- Pressing a programmed button on the remote will initiate the gate's movement (open or close).
- Pressing the button again during movement will stop the gate.
- A third press will reverse the gate's direction.
