How to Test it: 1. Adjust the knob to "TEST" button. 2. Place the device in a position close to you. 3. Whistle to the microphone of the item loudly, if the LED blinks Green, and you can hear beeping noise, then the item works properly.

How it works:
When the device is within range of the barking dog, an internal microphone picks up the sound and automatically emits a low-intensity ultrasonic sound which can be heard by dogs but is silent to humans.
Startled by the sound which is safe for humans and other pets yet effective , the dog should stop barking, as the dog stops barking the ultrasonic sound also stops.

Notes:
You should notice a reduction in the dog barking within the first two weeks after usage. Please note this product may not work on deaf or hearing-impaired dogs. It is recommended to be used outdoor, but the device can be used indoor
There are some situations where dogs become desensitized. To avoid this, when used indoor, only turn the device on during periods of unwanted barking.
