Some components on POS-478E are very sensitive to static discharges. To protect
it from unintended damage, be sure to follow these precautions:
1. Ground yourself to remove any static charge before touching your POS-478E.
You can do it by using a grounded wrist strap at all times or by frequently touching
any conducting materials that is connected to the ground.
2. Handle your POS-478E by its edges. Don't touch IC chips, leads or circuitry if not
necessary.
3. Do not plug any connector or jumper while the power is on.
4. Do not put your POS-478E unprotected on a flat surface, as the board has
components on both sides.
