This New Model VDS25 Vastar Anti-Bark Collar improved with a better senser and control chip. It helps to effectively stop barking by progressively increasing sound and shock which is controlled by a microprocessor distinguishing your dog's bark from other environmental noises and automatically delivers sound and shock after each bark, most of the pets will quickly understand the new sensation is telling her to be quiet.
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. The first two levels are only with progressively warning tone.
If your dog continues to bark through the rest five levels, 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.
Note for Use:
To test the collar: There is a test light (the clear plastic piece) in the package.If you want to test the collar with this light, just 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.
