The DOGLinsen 2-in-1 Bark and Shock Collar system consists of a remote control and a receiver collar. The receiver can function independently as an automatic bark collar or be controlled via the remote for training purposes.

- Automatic Bark Collar & Protection Mode: Automatically detects barking and pauses for 30 seconds after 7 consecutive triggers to prevent over-correction.
- 4 Effective Training Modes: Beep, Vibration (1-100 levels), Safety Shock (1-100 levels), and Automatic Mode with 5 adjustable sensitivity levels.
- Long Battery Life & Extended Range: Up to 30 days with remote use, 90 days for receiver only. Remote range up to 2800 feet.

4. Setup
4.1 Charging the Device
Before first use, fully charge both the remote control and the receiver. Use the provided 2-in-1 USB-C charging cable. The indicator light on the devices will show charging status.

Figure 4.1: Charging the remote and receiver.
4.2 Attaching the Collar Strap and Contact Points
Thread the collar strap through the receiver. Select the appropriate length of metal contact points (long or short) based on your dog's fur length. For dogs with shorter fur, use the shorter contact points. For dogs with longer or thicker fur, use the longer contact points to ensure proper contact with the skin. Place the black rubber sleeves over the metal contact points for comfort and to prevent direct metal-to-skin contact, especially for static shock mode.
4.3 Fitting the Collar
Proper fit is crucial for the collar's effectiveness and your dog's comfort. The collar should be snug but not too tight. You should be able to fit two fingers comfortably between the collar and your dog's neck. Ensure the contact points touch your dog's skin. If the collar is too loose, the stimulation may not be consistent, and if it's too tight, it could cause skin irritation.
