Product Installation:
1. Thread the dog belt through the dog belt jack on both sides of the host and the slot in front of the host, then insert and secure the dog belt buckle and fasten it.
2. Place the dog strap around the pet's neck, ensuring that the contact probe is directly below the neck and the host button is facing upwards. Adjust the tension of the dog strap until a finger can be inserted between the neck and the dog strap.
Product Testing:
1. Charging the device: First, charge the device through a charging cable. During charging, the shock mode indicator light is always red, and after fully charging, the charging indicator light is always blue.
2. Power on: Press and hold the "power button" for 3 seconds to turn on the machine. After turning on, a vibration and warning sound will sound, and the digital display light will light up for 5 seconds before turning off.
3. Click the "power button" once and the number will display "0". Blow air into the microphone sensor of the device or imitate the barking of a dog. The device will first sound a warning sound, then vibrate, and finally shock (a test light can be installed to test the shock situation)* After triggering the operation, the number will display "5" (sensitivity level 5). If the operation is not triggered, the number "5" will be automatically displayed after 10 seconds.

【 Function Operation 】:
Shutdown: Press and hold the "power button" for 3 seconds, and then shut down after a vibration.
Sensitivity setting: Click on the "power button", and the numbers will display 1-5 in sequence, representing sensitivity levels 1-5. When adjusting the sensitivity, the indicator light will light up and automatically turn off after 5 seconds of no operation.
Mode switching: Click the "Mode key" to switch modes. There are two modes as follows.
Non electric shock mode: When a barking dog is detected, a warning sound is emitted for 3 seconds, followed by a vibration for 3 seconds, continuously cycling until no barking dog is detected.
Electric shock mode (the electric shock mode indicator light remains red when triggered): When a dog barks is detected.
First time: Warning sound for 5 seconds+vibration for 3 seconds
Second time: Warning sound for 5 seconds+vibration for 3 seconds+electric shock for 1.5 seconds (weak electric shock)
Third time: Warning sound for 5 seconds+vibration for 3 seconds
Fourth time: Warning sound for 3 seconds+vibration for 3 seconds+electric shock for 1.5 seconds (conventional electric shock)
Fifth time: Warning sound for 3 seconds+vibration for 3 seconds+electric shock for 1.5 seconds (moderate electric shock)
Sixth time: Warning sound for 3 seconds+vibration for 3 seconds+electric shock for 1.5 seconds (strong electric shock)
After each triggering task is completed, it enters the sound detection state. If no dog barking is detected within 30 seconds, it will automatically reset to the first warning state for standby. If the dog barks continuously, the device will trigger the above six working modes in sequence.
Protection mode: After triggering the above six working modes, enter the 2-minute protection mode (digital display shows 8), and the electric shock mode indicator light will flash for 2 minutes before remaining on. If no dog barking is detected within 2 minutes, it will automatically reset to the first warning state for standby, and the indicator light will turn off (you can also click the "power button" to reset).
Low battery reminder: When the battery level is below 10%, the charging indicator light flashes.
