Please note: The update consists of a complete Main System software update, which needs to be run from a USB data carrier. To run this update, you need:

• A USB memory device (e.g. USB stick) with at least 2 GB storage capacity.
• A PC or notebook.

Step 1, Download and update USB stick preparation

1. Download the software update from https://xzent.com/support/software/. Unzip the update file.
