ESD prevention
• The equipment and floor are properly grounded.
• The equipment room is dust-controlled.
• Humidity and temperature are maintained at proper
levels.
• Wear an ESD-preventive wrist strap when inspecting or
handling a circuit board.
• Place any removed memory module, CF card, or
interface module face-up on an antistatic workbench or
in an antistatic bag.
• Touch only the edges, not any electronic components,
when inspecting or handling a memory module, CF
card, or interface module.
EMI prevention
• Take measures to protect the power system from the
power grid system.
• Keep the protection ground of the router as far away
from the grounding device or lightning protection
grounding device as possible.
• Keep the router far away from radio transmitters, radar,
and high-frequency or high-voltage devices.
• Use electromagnetic shielding when necessary.
