Charging and Battery
The device is equipped with a built-in 1500mAh rechargeable lithium battery. To charge:
- Connect the provided USB cable to the charging port on the device.
- Plug the other end of the USB cable into a compatible USB power source (e.g., charger, power bank, computer USB port, USB socket).
- The charging indicator light will show the charging status.
- A full charge typically takes 5 hours and provides approximately 30 days of standby use.
- Important: Do not use the device while it is charging.
Light Indicators:
- Low Battery: Flashes red constantly.

Important Considerations
For optimal effectiveness and safety, please note the following:
- Adaptation Period: Each dog learns at a different pace. Allow your dog up to 2 weeks to adapt to the device.
- Effective Range: While the device detects up to 33 feet, the best effect is typically within 25 feet. A smaller range generally yields better results.
- Obstacles: Low battery levels and physical obstacles (walls, dense foliage) will decrease the effectiveness of the bark control. Ensure a clear line of sight to the barking dog.
- Not for All Dogs: This device may not be suitable for:
- Dogs with hearing problems.
- Aggressive or violent dogs.
- Dogs under 6 months or over 8 years of age.
- Dogs weighing more than 50 pounds (some sources suggest this, though the product claims "all breeds and sizes").
- Environments with noisy surroundings that might interfere with bark detection.
- Situations with two or more dogs together, as it might be difficult to target specific barking.
