Installing the Certificate

US320f protects the thin client from erroneous writing to the flash memory by UWF (Unified Write Filter). Writing to flash
is valid as long as the thin client is active, but it will be lost if the thin client is restarted or shut down. Certificates installing
UWF in a valid state are lost when you restart or shut down the thin client.
