Pairing the Receiver Collar and Remote
If your collar is not responding, it may need to be re-paired. Follow these three simple steps:
- Press and hold the receiver's power button for 3 seconds until the red light flashes. Release immediately.
- Turn on your remote transmitter.
- Select a channel (1, 2, or 3) on the remote and press any vibration button. When you feel the collar vibrate, pairing is successful.

Fitting the Collar
Proper fit is crucial for the effectiveness and comfort of the collar:
- Ensure the receiver is centered on your dog's neck.
- Adjust the strap so that you can comfortably fit one finger between the collar and your dog's neck. It should be snug but not too tight.
- Limit collar wear to a maximum of 12 hours daily. Regularly check your dog's neck every 1-2 hours for any signs of irritation.
- The adjustable collar fits dogs with neck sizes from 8 to 27 inches, suitable for breeds weighing 10-120 lbs.
