About Q&A:
Q1: Will this device hurt my dog?
A1: No. uses 25kHz non-invasive ultrasound, which is inaudible to humans but audible to dogs. It does not cause pain or harm, but only reminds dogs to stop inappropriate behavior through discomfort. It is a gentle and proven training method.
Q2: Do all dogs react to this device?
A2: Most dogs that are sensitive to sound (especially dogs between 6 months and 8 years old) will react to ultrasound. However, a small number of dogs that are too old or have hearing loss may not react significantly. It is recommended to use commands and positive rewards during training for better results.
Q3: Do I need to get very close when using it?
A3: No. The effective distance is 35 feet (about 10 meters), which is very suitable for most indoor and outdoor scenes. You can safely control the dog's behavior at a certain distance and avoid getting too close to large or aggressive dogs.

Usage Steps:
1. Power-on preparation: Press and hold the main button for 2 seconds to start the device. The LED indicator lights up, indicating that it is ready.
2. Training starts: Aim the device at the dog (1-10 meters is the best distance, and the maximum support is 10 meters).
3. Press and hold the "transmit button" to emit 25kHz ultrasonic waves. It is recommended that each time should not exceed 10 seconds.
4. Observe the dog's reaction: If the dog stops barking or shows alert behavior, stop the ultrasonic wave immediately and give verbal praise or snack rewards.
5. Repeated training: After 7-10 days of positive training, the dog can gradually establish the behavioral logic of "barking = discomfort = no barking = reward".

Precautions:
1. Precautions for use: Avoid long-term continuous use. It is recommended to control each use within 10 seconds to avoid anxiety or resistance in the dog.
2. Not suitable for hearing-impaired or elderly dogs: The ultrasonic effect depends on the dog's hearing sensitivity. Dogs with hearing loss may react weakly.
3. Do not use it for a long time towards people or ears: Although humans cannot hear it, it is still recommended to avoid continuous emission towards human ears or other animals at close range.
4. Training with rewards is more effective: training with commands and snack rewards can enhance the dog's enthusiasm for learning good behaviors.
5. Avoid storage in humid environments: Although it supports outdoor use, the device is not waterproof, so avoid rain and water splashes.
6. Charge in time: If you find that the red light is flashing, please use the included 5V/2A adapter to charge in time, and it will be fully charged in about 1 hour.
7. Storage temperature recommendation: -10°C to 45°C: Do not store or use in extreme temperature environments to avoid affecting the life of the device.
