Sometimes it's useful for the GLD log files to be copied to a USB drive so they can be inspected by a third party. To do this:

- Ensure a USB key is inserted in the USB socket 
- Press the hardware "Setup" button (or the "Setup" soft key in Editor)
- Select the "Utility" tab at the top of the screen
- Select "Copy Logs To USB Key"

This will create a folder structure (if it does not already exist) and a file on the USB drive named something along the lines of "20170421-124005.tar" dependant on the date, in the folder /AllenHeathGLD/EventLogs.

This .tar file contains the logs you have just saved.
