Important Safety Information
- This device is intended for training purposes only and should not be used on aggressive dogs. Consult a professional trainer if your dog exhibits aggressive behavior.
- Do not leave the collar on your dog for more than 12 hours per day. Prolonged wear can lead to skin irritation.
- Regularly check your dog's neck for any signs of irritation, redness, or sores. If irritation occurs, discontinue use and consult a veterinarian.
- Ensure the collar is fitted correctly, allowing two fingers to fit snugly between the collar and your dog's neck. A collar that is too tight can cause discomfort or skin damage, while one that is too loose may not function effectively.
- Keep out of reach of children.

2. Fitting the Collar
Proper fit is crucial for the collar's effectiveness and your dog's comfort. The DINJOO Bark Collar is adjustable and suitable for dogs weighing 8-120 pounds with neck sizes ranging from 6-27 inches.
- Choose the appropriate length of contact points (long for thick coats, short for thin hair) and screw them securely onto the collar.
- Place the collar around your dog's neck, ensuring the main unit is positioned centrally on the dog's throat.
- Adjust the strap so that it is snug but not too tight. You should be able to comfortably fit two fingers between the collar and your dog's neck. The contact points must touch your dog's skin.
- Trim any excess strap length if necessary, ensuring a comfortable and secure fit.

3. Adjusting Sensitivity Levels
The collar features 8 adjustable sensitivity levels (1-8). A higher number indicates higher sensitivity, meaning the collar will activate with less intense barking. To adjust the sensitivity, short press the Sensitivity Adjustment button (M). The sensitivity level will be displayed on the screen.
- Levels 1-3: Recommended for noisy environments (e.g., dog park, areas with music or TV).
- Levels 4-5: Suitable for normal environments (e.g., during conversations, typical daily activity).
- Levels 6-8: Ideal for very quiet environments (e.g., during sleep time or late evening).

4. Smart Anti-Interference Technology
The DINJOO Bark Collar incorporates an advanced intelligent dog barking recognition chip and motion detection technology. This ensures that the collar only activates when your dog's vocal movement and barking are detected, effectively filtering out false triggers from other dogs' barking, head shaking, or environmental noise.

Maintenance
- Cleaning: Regularly clean the collar strap and the main unit with a damp cloth. Ensure the contact points are free of dirt or debris. Do not submerge the main unit in water, although it is IP67 waterproof, excessive exposure to water or harsh chemicals should be avoided.
- Storage: When not in use, store the collar in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Charge the collar when the battery indicator shows low power.
