YouLe Solar-Powered Outdoor Triple-Head Ultrasonic Dog Bark Deterrent, 65 Feet

I. Product Overview

The YouLe Ultrasonic Bark Deterrent features a multi-directional ultrasonic emission design and offers three ultrasonic modes: pulse, continuous, and variable frequency. It gently prompts dogs to stop barking using high-frequency ultrasonic waves inaudible to the human ear—no electric shocks or vibrations, making it more pet-friendly. Equipped with a high-definition LCD display, its operating status is clearly visible at a glance; it supports Type-C charging and features a built-in 2000mAh lithium battery with a battery life of up to 17 days. An optional solar panel is also available to further extend battery life. It can be used indoors, on balconies, or in yards to help correct your dog’s habit of barking without cause.

III. Operating Principle

The device has a built-in sound sensor that automatically activates the ultrasonic emitter when it detects a dog barking. Humans cannot hear ultrasonic waves, but dogs have keen hearing and can detect these warning sounds, causing them to stop barking. With consistent and proper use over time, this device helps dogs develop a conditioned response, reducing excessive barking. It is considered a gentle pet training tool.

IV. Explanation of the Three Ultrasound Modes

• Pulsed Ultrasound (Gentle Setting): Intermittent ultrasonic emissions cause minimal irritation, making this mode ideal for puppies and timid or sensitive dogs; it is recommended for first-time use.
• Continuous Ultrasound (Standard Mode): Emits a continuous ultrasonic signal, making it suitable for dogs that bark habitually on a daily basis.
• Variable-Frequency Ultrasound (High-Intensity Setting): Automatically adjusts the ultrasonic frequency to prevent dogs from developing a tolerance, making it ideal for dogs that bark persistently.

V. Instructions for Use

1. Equipment Placement Install or place the anti-bark device in an area where your dog frequently barks. Position it in a high place to prevent your dog from chewing on it. Aim the ultrasonic emitter toward the area where your dog is active, and do not block the emitter, as this will reduce its effectiveness. You can mount it on the wall using the holes on the back to save space.
2. Powering On and Adjusting Modes Turn on the device by turning the knob, and use the knob to switch between the three ultrasonic modes: pulse, continuous, and variable frequency. The LCD screen displays operating parameters and remaining battery life in real time, making it easy to check the device’s status. The device automatically emits ultrasonic waves when it detects a dog barking and automatically enters standby mode when it is quiet.
3. Shut Down and Store When not in use, turn the knob to the "OFF" position to turn off the device. It is recommended to fully charge the device before long-term storage. If you have the optional solar panel version, place it in a location with ample sunlight to help recharge the battery.

VI. Charging Instructions

1. Use the included Type-C cable to connect the device to the power adapter for charging; it takes about 4 hours to fully charge the device.
2. The LCD screen displays the battery level. When the battery is low, ultrasonic transmission performance will decrease; please recharge the device promptly.
3. Choose a model with a solar panel option to enable auxiliary charging in sunny conditions, extending the device’s overall battery life. Solar power serves only as a supplemental power source; when the battery is fully depleted, you’ll still need to use a Type-C wired fast charger.

Tip: Do not leave the device plugged in to charge for extended periods; unplug it as soon as it is fully charged.

VII. Important Notes

1. This product is a behavioral training aid for pets and is not a substitute for the owner’s companionship or positive reinforcement training. Results may vary depending on the dog’s breed, age, and hearing ability. For dogs with hearing loss, the bark deterrent effect will be very limited.
2. Do not block the device's ultrasonic emitter to prevent sound waves from propagating properly.
3. Place the device where your dog cannot chew on it to prevent damage to the device and avoid safety hazards.
4. Do not disassemble or modify the device on your own; do not use it close to a person's ear, an infant, or other small animals.
5. When using the device outdoors, avoid prolonged exposure to heavy rain to prevent water damage.

VIII. Frequently Asked Questions

1. Is your dog still barking, and is the device not working? ① Check that the device has sufficient battery power; ② Make sure the ultrasonic emitter is not blocked; ③ Try switching to the next higher ultrasonic mode; ④ Adjust the device’s position to bring it closer to the dog; ⑤ It may take some time for the dog to develop a conditioned response, so please continue training.
2. The screen isn't displaying, and the device won't turn on? The battery is completely drained. Charge it using a Type-C cable for a while, then try turning it on again.
3. Shorter battery life Frequent use of the ultrasonic function will increase power consumption; for the solar panel version, when there is insufficient sunlight, the solar charging efficiency decreases, resulting in a shorter battery life; if the device is not used for an extended period, it is recommended to recharge it periodically.
