    • Wait for 60 s or Click OK to install the ThinOS image and application packages. The thin client reboots automatically.
    • Click Manually to display the ThinOS image and application packages list. Select the ThinOS image and the application packages that you want to install and click OK to install these files. The thin client reboots automatically.

    NOTE:If the message is not displayed, the system is likely to have a license embedded in the BIOS. Or, the network is configured to automatically configure the Wyse Management Suite information and the device already has a TAL.
