Is the “High-Low” dial on the side of the unit used to adjust Volume?
The high-low dial on the side of the unit is used to customize the microphone sensitivity. This is not a volume setting. You may adjust the sensitivity of the bark sensor between High (if the dog is far away) and Low (if the dog is close to the unit, or if the unit is being used indoors). We recommend you start with the unit on low, and then increase the sensitivity as needed. There is no volume adjustment necessary on the Dog Silencer Pro, as the ultrasonic frequencies can travel up to 300 feet in a clear, unobstructed path. [Back to Top] I know it’s a training device, but my dog has no immediate/ initial reaction to the DSP sounds. It can be difficult to “wait” for this to work, but please be patient. This product is not designed to work instantly, but over a short training period. The dog needs time to learn that he’s going to hear this irritating noise each and every time he barks. Each dog will learn at their own pace, and unfortunately some dogs are more stubborn than others. Rem
