2.1 Anti-static Precautions
WARNING:
Failure to take ESD precautions during installation
may result in
permanent damage to the PUZZLE-M902 and severe injury to the user.
Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the PUZZLE-M902. Dry climates are especially susceptible to ESD. It is
therefore critical that whenever the PUZZLE-M902 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 PUZZLE-M902, place it on an
anti-static pad. This reduces the possibility of ESD damaging the
PUZZLE-M902.
2.2 Unpacking Precautions
When the PUZZLE-M902 is unpacked, please do the following:
Follow the anti-static precautions outlined in Section 2.1.
Make sure the packing box is facing upwards so the PUZZLE-M902 does not
fall out of the box.
Make sure all the components shown in Section 2.3 are present.
