<br />How it works:				
<br />  An internal microphone picks up the sound and the unit is automatically activated. The bark control collar starts with emitting an ultrasonic sound of 1 second as a warning at the first bark. At the second bark the collar emits an ultrasonic sound of 2 seconds. From the third bark the collar emits a 3 seconds ultrasonic sound and gives 2-3 seconds static shock. The dog should stop barking. If the dog barks within 1 minute after the first static shock, the collar sends out a 3 second ultrasonic sound and 2-3 second of static shock. If the dog stops barking, the collar resets itself to the lowest level and repeats the first 3 steps. The shock levels can be adjusted with the delivered screwdriver.
