With a screw-driver remove the screws from the top cover of your wireless sensor.
Place the provided Type N batteries on the sensor and screw the top cover back in.
It is important to ensure that all 4 screws are tightened correctly to prevent water or moisture from entering the sensor.
Hold the wireless sensor with your hand and move the magnet between 0 and 0,2 inches next to the sensor (hold this during almost 5 seconds).
Check if the status yellow light (right) of the ismartgate device blinks faster.
If the Status light doesn´t blink faster, please write us at email@example.com
