To start setting up the timing system, you need to lay out the loop cable.
- Lay out the loop cable on the ground and form a rectangle with 30 - 60 cm (1 - 2 ft.) width. To ensure accuracy, make sure the edges which are perpendicular to the direction of timing, should be as parallel as possible.
As a rough guide: If you require a very high precision (e.g. for a cycling event), you need to lay out the loop cable narrower. If you require less precision but a high read height, you need to lay out the loop cable wider. - Fix the loop cable on the ground, either using duct tape or a mat.

| Do not run other electrical sources over the loop cable. |
| Timing with the USB Timing Box can be very precise. To get the best results you also need to work precisely as well, and carefully follow all instructions. As an example, fixing the loop cable a few centimeters askew will have a negative effect on precision. |
