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.
