Please go to the system settings, in the【System Upgrade】item, click the【Check for Update】button.
If it finds that there is a new version that can be updated, click the【Download】button and wait for the update to be completed, then you can start to use the pen scanner.
Attention before update!!
Before executing the system update, the scanner must have sufficient battery power (more than 50%, and the power cord is connected to keep charging), please do not do any operation during the system installation, so as to avoid the interruption of the system installation, the upgrade failure, and the pen cannot be used normally!
