It is possible to upgrade the S-Series application license by browsing to Options - License. From this page it will be possible to upgrade user licenses.
Note: An operator will consume one user license.
If user licenses are to be upgraded (increased) click the Get Challenge button to generate a challenge and click the Copy button to copy this value to the PC clipboard. Paste this value to a text file and send this to your vendor that provided the S-Series. The vendor can then generate a new license key, which should be entered into the Upgrade field and click the Upgrade button to complete the license upgrade.
Note: It is possible to have up to 10 concurrent license requests that can be sent to the vendor. For example, if a request for 10 new licenses is sent to a vendor and in the time while waiting for the vendor to issue a new license key it was determined that a further 5 licenses were required, a new request could be sent for an additional 5 licenses. When the response is returned simply apply the new license keys.
