How to it works:
At the first bark, the Collar applies a short warning tone .If a second bark occurs within thirty seconds, a more intense tone is sounded. From the third bark, a more intense tone is sounded along with a short , mild shock. This pattern is repeated through 7 correction levels.
If your dog continues to bark, the more intense sound and shock are applies until your dog stops for thirty seconds, and then it will automatically resets to the first "tone only" level of correction.If the continuous stimulus reaches the 7 levels, then the Collar will stop working for 1 minutes to protect the dog.
There is a test light which you can contact the electrodes (on the collar) and the wires (in the tester), then blow air into the sensing hole (between the tow electrodes), the light will start to light up on your 3rd time to blow, and will be brighter and brighter on your following times to blow.
