My dog is not responding when I press the STIM button.
Check to see if the E-collar Module has been turned on.
If your range has reduced from the first time you have used it, please check to see if the battery is low in either the Handheld Device or E-collar Module.
Many factors can impact the range you have with the TEK SERIES Location and Training System.
You can verify the E-collar Module is delivering stimulation to your dog by placing the test light, enclosed in your kit, on the contact points.
