The Collar Receiver is beeping, but the dog is not responding to the stimulation.
Make sure the Stimulation Level is set at 2 or above.
Test the Collar Receiver with the Test Light (6B, page 13).
If the Test Light flashes, check the fit of the Collar Receiver.
Trim your dog’s hair where the Contact Points touch the neck and/or switch to the longer Contact Points.
Increase the Stimulation Level to the next level. If there’s still no response, try the next level and repeat. Also see finding the right recognition level.
