→Troubleshooting 8- SHS-3321 How to change the door direction

1. When you unplug the reed switch (sensor) and plug into the other port, it doesn’t detect the magnet at the first time.
2. You need to press “Open button” couple of times while the magnet is placed close to the reed switch (sensor)
3. Then the door lock will recognize the sensor from the other port.
4. After this, the door direction is already changed.
