Notice
Please read manual carefully before install, operate, or transport Leetop device.
Ensure that the correct power range is being used before powering the device.
Avoid hot plugging.
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.
Do not use cables or connectors other than described in this manual.
Do not use Leetop device near strong magnetic fields.
Backup your data before transportation or Leetop device is idle.
Recommend to transport Leetop device in its original packaging.
Warn! This is a Class A product, in a living environment this product may cause radio
interference. In this case, the user may be required to take practicable measures against the
interference.
Working in a high temperature environment for a long time, it is not recommended to touch
the shell to avoid burns.
ESD Warning
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 whe
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 sa
areas, which may include ESD floor and
table mats, wrist strap stations and ESD
safe lab coats.
• Avoidin handling circuit boards in
carpeted areas.
• Try t handle the board by the edges,
avoiding contact with components.
