Fitting the Collar Receiver
Proper fit of the collar receiver is crucial for consistent and effective operation. An improperly fitted collar may lead to inconsistent stimulation or skin irritation.
- The collar should fit snugly around your dog's neck, ensuring the contact points (probes) maintain consistent contact with the skin without rubbing.
- You should be able to fit only one finger comfortably between the collar strap and your dog's neck.
- Recheck the collar fit after several minutes of wear to ensure it remains secure and comfortable.

Operating Instructions
Operational Modes
The collar features three distinct operational modes, allowing you to select how it responds to your SportDOG system:
- Remote Trainer Mode: The collar responds only to signals from the Remote Transmitter. Use the dial to select one of 7 static stimulation levels (low, medium, or high ranges) and buttons for momentary (nick) or continuous stimulation. Vibration (buzz) and tone (beep) options are also available.
- Containment Mode: The collar responds only to the In-Ground Fence Transmitter. As your dog approaches the boundary, it will receive a warning tone and vibration, followed by one of 7 static stimulation levels, adjustable based on your dog's temperament.
- Combined Mode: The collar responds to both the Remote Transmitter and the In-Ground Fence Transmitter.
Tone, Vibrate, and Static Stimulation
The collar provides progressive feedback to your dog:
- Tone (Beep): An audible warning signal.
- Vibration (Buzz): A tactile warning signal.
- Static Stimulation: Seven levels of static correction are available, which you can select to match your dog's sensitivity and training needs.
