安全警示及使用注意事项 Notice
请在使用本产品前仔细阅读本手册，未经授权的操作会导致错误或意外。制造商对因错误操作而导致设
备出现的任何问题均不负责。
Please read manual carefully before install, operate, or transport Leetop device.
在给设备供电之前，确保使用正确的电源范围。
Ensure that the correct power range is being used before powering the device.
避免热插拔设备接口。 Avoid hot plugging.
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.
请勿使用本手册提及以外的线缆。
Do not use cables or connectors other than described in this manual.
避免在强磁场环境下使用本设备。
Do not use Leetop device near strong magnetic fields.
长期不使用及运输前需要对数据进行备份。
Backup your data before transportation or Leetop device is idle.
推荐使用原包装进行运输。
Recommend to transport Leetop device in its original packaging.
警告！ 此为A级产品，在生活环境中，该产品可能会造成无线电干扰。在这种情况下，可能需要用
户对干扰采取切实可行的措施。
