- Place the receiver on your dog's neck, ensuring the unit is positioned centrally under the chin or on the side of the neck.
- Adjust the strap so it is snug but not too tight. You should be able to fit two fingers comfortably between the collar and your dog's neck.
- Trim any excess strap length if necessary, and use the provided clip or loop to secure the loose end.
- Do not leave the collar on your dog for more than 12 hours a day to prevent skin irritation.

1. Pairing the Receiver with the Remote (if necessary)
If your receiver is not responding to your remote, it may need to be paired. Refer to your remote's manual for specific pairing instructions. Generally, the process involves:
- Turn on the receiver.
- Press and hold the power button on the receiver until the indicator light flashes rapidly.
- Within a few seconds, activate a command (e.g., vibration or beep) on your remote.
- The receiver's light should become solid, indicating successful pairing.
2. Training Modes
The PD520V receiver supports three primary training modes:

- Beep Mode: Emits an audible tone. Useful for initial attention-getting or as a warning signal.
- Vibration Mode (1-10 Levels): Delivers a gentle vibration. The intensity can be adjusted from level 1 (mildest) to level 10 (strongest) via the remote. Start with lower levels and increase as needed.
- Beep & Vibration Mode (1-10 Levels): Combines an audible beep with vibration. This can be used for more pronounced cues or for dogs that respond better to a combined stimulus.
Always use the lowest effective level for training. Consistent and positive reinforcement training methods are recommended.
3. Waterproof Feature (IPX7)
The receiver is IPX7 waterproof, meaning it can withstand immersion in water up to 1 meter for 30 minutes. This allows your dog to wear it during swimming, bathing, or in rainy/snowy conditions.

While waterproof, it is recommended to dry the receiver thoroughly after exposure to water to prolong its lifespan.
