When the outdoor bark control device detects dog barking within its effective range, its built-in microphone captures the sound, triggering automatic activation.
The device then emits an ultrasonic sound—audible to dogs but inaudible to humans.
The high-pitched ultrasonic sound startles the dog, prompting it to stop barking. Over time, the dog learns to associate its barking with this unpleasant sound, forming a long-term training effect.
Equipped with 3 adjustable range levels and a test mode, the device effectively covers distances up to 50 feet (15 meters).
Once the dog stops barking, the ultrasonic sound automatically ceases, ensuring a gentle yet highly effective training method.

Frequency & Range Settings
Hold down the Sensitivity button to adjust the sensitivity level between 1–4. The activation of the ultrasonic sound is triggered by the volume and distance of the detected dog barking. Three range levels are available for precise adjustment:
Low Range: Up to 15 feet (5 meters) – Recommended for indoor testing.
Medium Range: Up to 30 feet (10 meters).
High Range: Up to 50 feet (15 meters).

Important Pre-Use Information
This bark control device is designed to provide pet owners with a professional, hassle-free pet training solution. It automatically activates when detecting barks within 50 feet, emits ultrasonic sound to stop barking, and shuts off the sound once the dog quiets down. Key product features:
Durable and weatherproof, suitable for outdoor use.
LED light flashes to indicate low battery.
Powered by a 9V battery (not included).

Safety & Usage Notes
During setup, mounting, or hanging, keep the device at least one arm's length away from human ears. This prevents potential hearing damage if a dog barks and triggers the ultrasonic sound during these processes.
Dogs that are deaf or hearing-impaired may not respond to the device.
Some dogs may initially feel afraid or dislike the ultrasonic sound and fail to stop barking immediately. Please allow up to 2 weeks of consistent use for effective training results.
If the device shows no effect on your dog, try adjusting the frequency (sensitivity level) and complement the training with reward-based positive reinforcement and appropriate disciplinary measures.
