Notice

Please read manual carefully before install, operate, or transport MiiVii 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
Miivii device.
Do not use cables or connectors other than described in this manual.
Do not use MiiVii device near strong magnetic fields.
Backup your data before transportation or MiiVii device is idle.
Recommend to transport MiiVii device in its original packaging.
