Setup
Charging the Units
Both the remote transmitter and the receiver collar are equipped with quick-charge Lithium Ion batteries. Fully charge both units before initial use.
- Connect the charging adaptor to the charging cradle and plug it into a power outlet.
- Place the receiver collar and remote transmitter into the charging cradle. Ensure they are seated correctly for charging.
- A full charge typically takes approximately 2 hours.
- The receiver battery provides 140-160 hours of use per charge, while the transmitter battery offers 40-60 hours.
- Built-in low battery indicators will alert you when charging is needed.
Attaching Contact Points
Choose between the standard or long contact points based on your dog's coat length. The contact points must make direct contact with the dog's skin for effective stimulation. Screw the chosen contact points firmly onto the receiver.
Fitting the Collar
Proper fit of the receiver collar is essential for consistent and safe operation. The collar should be snug, allowing the contact points to make reliable contact with the skin, but not overly tight to cause discomfort or restrict breathing.
- The collar is designed for dogs weighing 8 pounds and up, with neck sizes ranging from 5 inches to 22 inches.
- Position the receiver centrally under your dog's neck.
- Verify the fit by attempting to slide one finger snugly between a contact point and your dog's neck. If you can fit more than one finger, the collar is too loose.

Operating Instructions
Transmitter Controls
The remote transmitter is designed for "no-look" operation, allowing you to focus on your dog. Familiarize yourself with the button layout and functions:
- Intensity Dial: This rotary dial allows you to select one of 21 levels of static stimulation. Turn the dial to increase or decrease the intensity.
- V/T Button: Activates either the vibration or tone function, depending on the current mode setting.
- High, Medium, Low Buttons: These dedicated buttons deliver continuous static stimulation at pre-set high, medium, or low intensity levels.

Stimulation Modes and Expandability
The SportHunter 1225X offers versatile training options:
- Static Stimulation: Provides a safe, momentary static pulse. The intensity can be precisely adjusted using the 21 levels available.
- Vibration: Delivers a non-stimulatory vibration, useful for attention-getting or as a warning.
- Tone: Emits an audible tone, which can be used for positive reinforcement or as a pre-correction warning.
The system is designed for multi-dog use and can be expanded to control up to 3 dogs simultaneously with the purchase of additional Add-A-Dog® Collars.

Troubleshooting
If you encounter issues with your SportDOG SportHunter 1225X, refer to the table below for common problems and their solutions. For more complex issues, consult the full Operating Guide or contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Collar not delivering stimulation, tone, or vibration. | Low battery in receiver or transmitter; improper contact point fit; receiver not turned on; unit not properly paired with transmitter. | Ensure both units are fully charged; adjust collar to ensure contact points touch skin; turn on receiver; re-pair transmitter and receiver according to the operating guide. |
| Reduced operating range. | Environmental obstructions (e.g., dense foliage, terrain); low battery in transmitter or receiver; loose or damaged antenna on transmitter. | Move to a more open area; fully charge both units; ensure the transmitter antenna is securely attached and undamaged. |
| Unit fails to power on. | Battery is completely drained or unit is not properly charged. | Place the unit on the charging cradle and allow it to charge for at least 2 hours. Verify charging indicator lights. |
| Dog does not respond to stimulation. | Stimulation level is too low; contact points are not making proper contact; dog has become accustomed to the level. | Increase the stimulation level gradually; ensure proper collar fit and contact point placement; re-evaluate training approach. |
