Summarize:

If you have children to prevent them from treating the treadmill as if it were a toy. Position the television on stable furniture far enough away where you cannot fall into it and where it is not affected by any bouncing caused by the treadmill.
Place your treadmill in a safe location away from walls, windows, or mirrors that can cause extreme injuries if you fall down or off the treadmill. Remove any existing sharp objects or household goods from around the treadmill, such as pointy sculptures or furniture with sharp corners. Place power cords or cables away from foot traffic surrounding the treadmill so you do not trip or fall as you step on and off the treadmill. Store your treadmill in a locked room. Place a television straight across the room in front of your treadmill so you can see it easily while you exercise.
