WARNING:
Failure to take ESD precautions during the maintenance of the
AFL2-W21A/AB-H61 may result in permanent damage to the
AFL2-W21A/AB-H61 and severe injury to the user.
Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the AFL2-W21A/AB-H61. Dry climates are especially susceptible to ESD. It is
therefore critical that whenever the AFL2-W21A/AB-H61 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 AFL2-W21A/AB-H61, place it
on an antic-static pad. This reduces the possibility of ESD damaging the
AFL2-W21A/AB-H61.
 Only handle the edges of the PCB: - When handling the PCB, hold the PCB
by the edges.
