2.2Unpacking Precautions
Some components on ROCKY-3702EV SBC are very sensitive to
static electric charges and can be damaged by a sudden rush of
power. To protect it from unintended damage, be sure to follow
these precautions:
üGround yourself to remove any static charge before touching your
ROCKY-3702EV SBC. 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.
üHandle your ROCKY-3702EV SBC by its edges. Don’t touch IC
chips, leads or circuitry if not necessary.
üDo not plug any connector or jumper while the power is on.
üDo not put your ROCKY-3702EV SBC unprotected on a flat surface
because it has components on both sides.
