In fact, thissetting determines the correct operation of the product.It ensures detection of any barking but helps avoid unnecessary detection.The detection, must therefore be sufficiently sensitive but not overly sensitive. In factory, barkingdetection sensitivity is set on the maximum position (maximum sensitivity).To adapt the detection sensitivity to the barking strength of your dog, you should proceed asfollows:- Remove the 2 screws from the battery cover with a screwdriver.- Remove the battery cover.- Carefully turn the setting screw according to the sensitivity you wish (See. Diagram 5)Caution: the adjustment system has a stop for the minimum sensitivity and a stop for themaximum sensitivity. Turn delicately and without forcing with the supplied screwdriver.Number of beep sounds heard whenswitching modes Mode Operation1 1 ultrasounds only2 2 vibrations only3 3 ultrasounds + vibrations
