• Make sure that the No-Bark Collar Unit is properly fitted on your dog. Loosely fitted collar will affect performance. For proper fit, the collar should be snug, yet loose enough to allow two fingers to fit between the strap and your dog's neck.
• Make sure that there is good skin contact where the No-Bark Collar Unit touches the neck area. If necessary, trim your dog’s hair to ensure good contact.
• Check if the battery has drained out.
• If you are certain that your dog gets the ultrasonic correction, however is still not responding, try the next level higher (see “Adjust Correction Level” page 11).
