Open the app, go to the Dogs screen, then tap Connect to Manage. Tap Fences at the bottom of the screen then tap Add Fence and follow the step-by-step instructions in the app.
You’ll need a fully-charged collar and your phone. Go outside with the collar and the app. Follow the instructions in the app to connect your phone to the collar, wait until your collar has acquired a GPS signal, and you’re ready to create a fence.
Move to a starting landmark. Hold the collar with the GPS antenna facing the sky. Tap start on the app and walk the boundary. As you walk SpotOn automatically places one virtual fence post about every 5 feet. You don’t need to walk in straight lines--the boundary can be curved if needed. And if you stand still for a moment SpotOn will wait until you move.
When you approach the starting point the app will automatically inform you to tap finish. SpotOn will complete the fence and then ask you to name it.
