Setup
1. Charging the Units
Both the handheld transmitter and the collar receiver are powered by rechargeable lithium-ion batteries. Fully charge both units before initial use. Charging typically takes approximately 2 hours.
- Connect the charging adapter to a power outlet.
- Attach the charging clips to the charging ports on both the transmitter and receiver.
- The indicator lights will show charging status (refer to the specific LED indicators in your quick start guide for details).
2. Fitting the Collar Receiver
Proper fit of the collar receiver is crucial for consistent stimulation and accurate health monitoring. The contact points must make direct contact with your dog's skin.
- Ensure the collar is centered on your dog's neck, with the receiver positioned below the chin.
- Adjust the strap so it is snug, allowing only one finger to fit comfortably between the strap and your dog's neck.
- If your dog has long or thick fur, use the longer contact points provided to ensure proper skin contact.

- Place the test light tool over the contact points on the collar receiver.
- Select a low stimulation level on the transmitter.
- Press the static stimulation button. The test light should illuminate, indicating the stimulation is functioning.

Maintenance
To ensure the longevity and optimal performance of your SportDOG FieldSentinel 1825 system, follow these maintenance guidelines:
- Keep Dry: While the units are waterproof, it is recommended to dry them thoroughly after exposure to water.
- Clean as Needed: Regularly clean the collar receiver, especially the contact points, to remove dirt, debris, and oils that can affect performance. Use a damp cloth and mild soap if necessary.
- Charge Batteries: Recharge the lithium polymer batteries as required to maintain battery health and ensure the system is ready for use. Avoid fully depleting the batteries frequently.
- Inspect Components: Periodically inspect the collar strap, contact points, and charging ports for any signs of wear or damage. Replace worn parts as needed.
Troubleshooting
If you encounter issues with your FieldSentinel 1825 system, consider the following troubleshooting steps:
- No Stimulation/Vibration/Tone:
- Ensure both the transmitter and receiver are fully charged.
- Verify the collar receiver is turned on and properly paired with the transmitter.
- Check that the contact points are making proper skin contact. Adjust the collar fit or use longer contact points if necessary.
- Test the static stimulation with the test light tool.
- Poor Range:
- Ensure the transmitter antenna is not obstructed or damaged.
- Environmental factors (e.g., dense foliage, terrain, large metal structures) can affect range.
- Check battery levels on both units.
- Inaccurate Health Alerts:
- Ensure the collar is fitted snugly and the sensors are making good contact with the dog's skin.
- Clean the sensor area on the collar receiver.
- Ensure the dog is not excessively wet or dirty, which can interfere with sensor readings.
- Unit Not Turning On:
- Ensure the unit is fully charged.
- Attempt a reset by holding the power button for an extended period (refer to the full product manual for specific reset procedures).
