Setup
1. Charging the System
The SportTrainer SD-875E system utilizes quick-charge lithium-ion batteries. Before first use, fully charge both the Remote Transmitter and the Collar Receiver. A full charge typically takes approximately 2 hours.
- Connect the charging adapter to the charging ports on both the remote and collar.
- The charging indicator lights will show the charging status. Refer to the device's display for battery life.
2. Fitting the Collar Receiver
Proper fit of the Collar Receiver is crucial for effective and humane operation. The collar should be snug, allowing the contact points to make consistent contact with your dog's skin without causing discomfort.

- Position the Collar Receiver on your dog's neck, ensuring the contact points are beneath the neck.
- The collar should be centered, and the contact points should touch the skin.
- Check the fit by attempting to slide one finger under the strap. If more than one finger fits, the collar is too loose. If no fingers fit, it is too tight.
- Recheck the fit after several minutes of wear to ensure it remains secure and comfortable.
3. Powering On/Off
To power on the Collar Receiver, press and hold the power button until the indicator light illuminates. To power off, press and hold the power button until the indicator light turns off. The Remote Transmitter typically remains in a standby mode and does not have a dedicated power-off button, conserving battery life automatically.

3. Multi-Dog Training

Maintenance
1. Cleaning
Regular cleaning of the Collar Receiver is recommended, especially after use in wet or dirty conditions. Clean with water and a mild soap as needed. Ensure all components are dry before charging or storing.
2. Battery Care
To maximize battery life, fully charge the Remote Transmitter and Collar Receiver when the battery indicator shows low power. Avoid prolonged storage of the device with a completely depleted battery. The system is designed for hours of runtime on a single charge.
3. Contact Point Inspection
Periodically inspect the contact points on the Collar Receiver for any signs of wear or corrosion. Ensure they are clean and free of debris to maintain effective contact with your dog's skin.
Troubleshooting
- Collar Receiver Not Responding: Ensure the collar is powered on and fully charged. Verify that the Remote Transmitter is also charged and within range. Check if the collar is properly paired with the remote.
- No Stimulation/Tone/Vibration: Confirm the collar is fitted correctly and the contact points are making proper skin contact. Increase the stimulation level on the remote. Test the function in a controlled environment.
- Charging Issues: Ensure the charging adapter is securely connected to both the device and a working power outlet. Check the charging ports for any debris. If the issue persists, contact customer support.
- Inconsistent Range: Environmental factors such as terrain, weather, and electromagnetic interference can affect range. Ensure a clear line of sight between the remote and collar when possible.
