The static electricity on fingers or other electrical conductors may damage the mainboard or other electrostatic-sensitive devices and shorten the product life.

Observe the following:

  • Place unused products into ESD bags to prevent direct contact with humans during transportation and storage.
  • Before products arrive at an ESD area, store them in their own packages.
  • Place the product package on a grounded surface before taking out the product.
  • Do not touch pins or circuits.
