When using an external storage device, to ensure the consistent transfer speed and the external device and the system storage device, Techman SSD is the only available to be used. If the transfer speed is inconsistent, it will not be able to switch to the automatic mode. In addition, the same situation occurs when installed an external USB storage device to the electric control box. If unable to switch to auto mode, please check whether it installed a storage device other than Techman SSD first. If there is no way to rule out the situation, contact qualified and authorized service personnel.
