Electronic components and circuits are sensitive to
ElectroStatic Discharge (ESD). When handling any
circuit board assemblies including Leetop Tech COM
Express carrier assemblies, it is recommended that
ESD safety precautions be observed. ESD safe best
practices include, but are not limited to: • Leaving
circuit boards in their antistatic packaging until
they
are ready to be installed. • Using a grounded wrist
strap when handling circuit boards, at a minimum
you should touch a grounded metal object to
dissipate any static charge that may be present on
you. • Only handling circuit boards in ESD safe areas,
which may include ESD floor and table mats, wrist
strap stations and ESD safe lab coats. • Avoiding
handling circuit boards in carpeted areas. • Try to
handle the board by the edges, avoiding contact
with components.

要正确关闭电源，请先关闭Ubuntu系统，然后再切断电源。由于Ubuntu系统的特殊性，在Nvidia的开发套件 (沥拓
套件)上，如启动未完成的时候强行断电，会有0.03%的概率出现异常，进而导致设备无法启动。
To properly turn off the power, please shut down the Ubuntu system first, and then cut off the power. Due to
the particularity of the Ubuntu system, on the Nvidia developer kit, if the power is turned off when the
startup is not completed, there will be a 0.03% probability of abnormality, which will cause the device to fail
to start. Due to the use of the Ubuntu system, the same problem also exists on the Leetop device.
