2. Important Safety Information
- Age and Health: This collar is suitable for dogs weighing 5 to 150 lbs and with neck sizes 8 to 25 inches. Do not use on puppies under 6 months old or dogs with health issues, skin conditions, or heart problems. Consult a veterinarian if unsure.

- Duration of Wear: Do not leave the collar on your dog for more than 12 hours per day. Prolonged wear can lead to pressure necrosis (bed sores).

- Supervision: Always supervise your dog when the collar is in use, especially during initial training sessions.
- Water Exposure: The receiver collar is IP67 waterproof, but the remote control is not. Keep the remote away from water.
- Accidental Activation: Utilize the security on/off switch on the remote to prevent accidental activation of training functions.
- Not for Aggressive Dogs: This device is not intended for use with aggressive dogs. Seek professional behavioral consultation for aggression issues.

5.2 Attaching Contact Points and Protective Covers
Select the appropriate metal prongs based on your dog's coat length. Use shorter prongs for short-haired dogs and longer prongs for long-haired dogs. Always use the protective rubber covers to prevent skin irritation.
- Screw the chosen metal prongs onto the receiver collar.
- Place the protective rubber covers over the metal prongs.
5.3 Fitting the Collar
Proper fit is crucial for both comfort and effectiveness.
- Place the receiver collar around your dog's neck, ensuring the contact points are positioned underneath, touching the skin.
- Adjust the strap so it is snug but not tight. You should be able to fit two fingers comfortably between the strap and your dog's neck.

6.2 Selecting Collar Modes
The collar offers three distinct modes, selectable via the remote control:
- Bark Control Mode: The receiver collar operates automatically, detecting and responding to your dog's barking with pre-set corrections (beep + vibration, or beep + vibration + shock). The remote is not required for this mode to function.
- Dog Training Mode: The receiver collar responds only to commands sent from the remote control. This mode is used for active training sessions.
- All Mode: The receiver collar functions as both an automatic bark control device and responds to remote commands.

6.3 Using Training Functions (Dog Training Mode / All Mode)

- Vibration Function: Delivers a tactile vibration. Adjustable levels 1-16. A gentle deterrent or attention-getter.

7. Bark Control Mode
In Bark Control Mode, the collar automatically detects and corrects excessive barking. It uses an advanced smart chip to distinguish your dog's barking from other noises and vocal cord vibrations.
7.1 Adjustable Sensitivity
The bark collar has 5 adjustable sensitivity levels. A higher sensitivity level means the collar will detect barking more easily. Adjust this based on your dog's barking habits and environmental noise.
7.2 Working States
The bark control mode offers two working states:
- Beep + Vibration: Provides an audible warning followed by a vibration.
- Beep + Vibration + Shock: Provides an audible warning, then vibration, and finally a static stimulation if barking persists.
Select the appropriate working state and sensitivity level via the remote control settings for Bark Control Mode.

- Strap Inspection: Periodically check the collar strap for wear and tear. Replace if damaged.
- Storage: When not in use, store the device in a dry place at room temperature.
- Battery Care: Avoid fully discharging the batteries frequently. Charge them when the low battery indicator appears.
