Setting up your Wireless Dog Fence will only take a few minutes and is easy. The wireless fence transmitter plugs into any standard 110 volt outlet. Since the signal will transmit reliably through walls and other obstructions, it can be placed in any convenient and discreet location, typically in the garage, tool shed, or a closet. Once you have set up the Instant wireless dog fence, you can now adjust the range that is appropriate for your dog and your yard.
