1. This barking prevention device uses harmless sound waves (15-30khz) to stop dogs from barking. It is suitable for most dogs between 6 months and 8 years old.
2. The dog barking prevention device sets three ultrasonic frequencies: sweep mode 15KHz-30KHz, fixed frequency 20KHz, and fixed frequency 15KHz. The rotary switch points to OFF for the off state. Pointing to different modes will emit sound waves of different frequencies. The sweep mode refers to the ultrasonic waveform between 15-30khz. The sweep mode refers to the ultrasonic waveform automatically switching between 15-30khz. The fixed frequency mode means that the ultrasonic waveform is fixed.
3. After turning on the switch, the anti-barking device will be in working standby mode. When the dog hears an abnormal roar, the product will automatically emit an ultrasonic frequency. At this time, the blue light will be on for 5 seconds to stop the dog from barking, and then automatically enter standby mode after 5 seconds.
4. Easy to install, can be hung on the wall, table, tree or placed in the garden.
5. Equipped with a 1200mAh battery, it can be used for a long time.
