3.1 Anti-static Precautions
WARNING:
Failure to take ESD precautions during the maintenance may
result in permanent damage to the system and severe injury to the
user.
Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the u Smart3400. Dry climates are especially susceptible to ESD. It is
therefore critical that whenever the u Smart3400 is accessed internally, or any other
electrical component is handled, the following anti-static precautions are strictly
adhered to.
 Wear an anti-static wristband: - Wearing a simple anti-static wristband
can help to prevent ESD from damaging the board.
 Self-grounding: - Before handling the board touch any grounded
conducting material. During the time the board is handled, frequently
touch any conducting materials that are connected to the ground.
 Use an anti-static pad: - When configuring the u Smart3400, place it on
an antic-static pad. This reduces the possibility of ESD damaging the
uSmart3400.
 Only handle the edges of the PCB: - When handling the PCB, hold the
PCB by the edges.
