Electrostatic discharge is hazardous to the electronic equipment. Wear an ESD
wrist strap and ensure that the strap is grounded properly before touching the
equipment and boards, to protect the static-sensitive components against
electrostatic discharge of the human body. Otherwise, the equipment may be
damaged or the service may be interrupted.
