When the Antibarking Dog Silencer within range of a barking dog, an internal microphone picks up the sound and the unit is automatically activated and emits an ultrasonic sound. This signal can be heard by dogs but is silent to humans. Startled by the high-pitched sound that is safe and effective, the dog should stop barking, as it will associate its bark with this unpleasant noise. When the dog stops barking the ultrasonic sound stops as well. If there is a continuous use of the Dog Silencer some dogs may become desensitized. To avoid this, only turn the outdoor bark control on during periods of unwanted barking (e.g. switch off while the dog sleeps). How to Test it: 1. Adjust the knob to "TEST" button. 2. Place the item to a position which is one arm's length away from you. 3. Whistle to the microphone of the item loudly, if the LED blinks green and you can hear beeping noise, then the device is working properly. Effective Range: Level 1: Up to 15 feet Level 2: Up to 30 feet Level 3: Up to 50 feet
