Setup
1. Charging the Collar
Before first use, fully charge the collar. Connect the USB charging cable to the collar's charging port and a compatible USB power source (e.g., USB adapter, power bank, car charger, laptop/PC).
- Charging time: Approximately 2 hours.
- Battery life: Up to 15 days of work time on a full charge.

2. Attaching Contact Points and Protective Covers
Screw the appropriate contact points onto the collar module. For added comfort and protection, especially for dogs with sensitive skin or short fur, place the silicone protective covers over the contact points.

3. Fitting the Collar
Proper fit is crucial for the collar's effectiveness and your dog's comfort. The collar should be snug enough for the contact points to touch the skin, but not so tight as to restrict breathing or cause discomfort.
- Place the collar around your dog's neck.
- Adjust the strap so that you can fit one or two fingers comfortably between the collar and your dog's neck.
- Ensure the contact points are positioned under your dog's throat, making good contact with the skin.
- The collar is suitable for dogs weighing 8 to 150 lbs with neck sizes ranging from 7.8" to 27".


Operating Instructions
1. Power On/Off
Press and hold the On/Off button (often labeled 'M' or a power symbol) for a few seconds to turn the collar on or off. The display will light up when powered on.
2. Selecting Working Mode
The collar offers two primary working modes:
- No Shock Mode: Beep + Vibration (Green Light on display).
- Shock Mode: Beep + Vibration + Static Shock (Red Light on display).
Press the 'M' button briefly to switch between these modes. Choose the mode that best suits your dog's training needs and temperament.


3. Adjusting Sensitivity Levels
The collar has 5 adjustable sensitivity levels (0-5). A higher number indicates higher sensitivity, meaning the collar will activate with less intense barking. Adjust the sensitivity using the dedicated buttons (often '+' and '-' or similar) on the collar module.
- Levels 3-5: Recommended for quiet environments or dogs with softer barks.
- Levels 1-3: Recommended for noisy environments or dogs with louder barks.

4. Intelligent Protection System
To ensure your dog's safety and prevent over-correction, the collar incorporates an intelligent protection system. If the collar activates 6 times continuously within a short period, it will automatically stop working for 30 seconds. The digital display will show "8" during this protection period. This feature prevents unnecessary punishment and allows your dog to calm down.

Maintenance
- Cleaning: Wipe the collar module and strap with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Contact Points: Regularly check the contact points for dirt or debris and clean them to ensure proper conductivity.
- Storage: When not in use for extended periods, store the collar in a cool, dry place. Ensure it is fully charged before storing to prolong battery life.
- Waterproof Care: Although IP67 waterproof, always ensure the charging port cover is securely closed before exposing the collar to water.
