3. Reboot Pi-Order

• Unplug the Pi-Order from the power outlet then from the ethernet connection
• Place Pi-Order where you would like it to reside then plug back into a power outlet

4. Select Product for Ordering

• Spin selection knob until the lighting tree shows the colors corresponding to the product you would like to order
