• When moving a host interface from a cold place, such as an un-
conditioned store house in winter, to a warmer place such as an air-
conditioned room, the severe temperature change may result in
condensation forming.
To avoid this, allow the packed host interface sufficient time in the warmer
place (one hour for each 15°C of temperature difference) to adapt to the
new temperature.
• When handling host interfaces, make sure to wear a wrist strap or touch a
metal part to discharge the human body's natural static electricity. Failure
to discharge static electricity may cause device failure.
• Leave the host interface in its package until ready to install it.
