1. The principle of the dog repeller:

   This product, an ultrasonic dog repeller, is primarily designed for outdoor environments to prevent dogs from attacking. When you encounter a dog that is attempting to attack you, you can take out this 'super weapon' ultrasonic dog repeller and emit ultrasonic waves at the dog. The 130dB ultrasonic waves are very stimulating to a dog's hearing. The bright LED flashes can also make the dog clearly understand the source and location of the sound, thereby understanding that the weapon in your hand is aimed at it. The longer it stays in this position, the greater the harm to it, and it will panic and leave.

2. Ultrasonic Dog Repeller Usage Method:

(1) Ultrasonic dog repeller can also be used as a flashlight: turn the switch on the bottom of the product to the "Light" position, and press the "ON" button on the top of the product, and it can be used as a flashlight function.

Step 2: Train the dog with the Ultrasonic Dog Repeller: Turn the dial on the bottom of the product to the "Train" position, and press the "ON" button on the top of the device. The ultrasonic sound will be emitted, and you can then start training the dog.

(3) Ultrasonic dog repeller: Turn the switch on the bottom of the product to the "Chaser" position, and press the "ON" button on the top of the product. When used against aggressive dogs, they will flee.

3. Notes:

When this device is not in use, please set the gear selection switch to the "Chaser" position to avoid power consumption. The following conditions may not lead to significant dog driving effects:

（1）A dog that is raised by itself knows that its owner will not harm it.

（2） A dog with its master—a dog with clout; a well-trained large dog—well-trained.

When the battery voltage is too low, the ultrasonic energy emitted by the product will decrease.

 (4) In the dog-chasing mode, the power output is strong, resulting in higher power consumption. Please do not hold the switch for a long time. Generally, press it for 3-5 seconds, then release the switch before pressing it again.

This product emits a strong ultrasonic power, so please do not direct it at a person's ear when using it.
