How does it work?
Insert a standard 9-volt battery into the Ultrasonic Dog Bark Controller in Birdhouse Shape. The unit is automatically activated by the sound of barking. When the device is within the range of a barking dog, the microphone will isolate and pick up the barking to emit an ultrasonic sound to silence the dog. The anti-bark device has three range levels, including a test mode, and is effective up to 50 feet.

Note:
This product is only suitable for outdoor use.
Don't touch by children.
The product will not work on deaf or hearing impaired dogs.
Human cannot hear the ultrasonic sound, however precautions should be taken when preparing the outdoor bark control for use.
The Ourdoor Bark Contral is weatherproof.However,if water enters into the microphone it may disrupt the unit's operation. After the micorphone is dry it will resume working properly.
