Electronic components and circuits are very sensitive to electrostatic discharge. Although our company
designs anti-static protection for the main interfaces on the card when designing circuit board products,
it is difficult to achieve anti-static safety protection for all components and circuits. Therefore, it is
recommended to observe anti-static safety precautions when handling any circuit board component
(including RTSS-X502N). Anti-static safety protection measures include, but are not limited to the
following:
a) The smart box should be placed in an anti-static bag during transportation and storage, and then the
board should not be taken out during installation and deployment.
b) Before touching the smart box, discharge the static electricity stored in the body: wear a discharge
grounding wrist strap.
c) Operate the smart box only within the safe area of the electrostatic discharge point.
d) Avoid moving smart boxes in carpeted areas.
