To get these tunings back you'd need to have saved them to your computer, or you can simply recreate them in Variax WorkBench.  If the tunings were part of the original factory settings, you can perform a factory reset to the guitar, but if you have any special presets you should save these to computer before resetting the guitar.

From the documentation on this site:

VARIAX Electric and Acoustic Guitars and Basses

You will have to connect your VARIAX to the WORKBENCH, POD XT/X3 LIVE, or VETTA II to reset your factory default settings. Then you will have to connect your interface to your computer. Here are the instructions for each:

Variax Electric 300, 500, 600, 700

  These instruments can only be returned to factory reset by reinstalling the flash memory.   Connect the Variax digital guitar cable to your Variax interface (you will need to have the unit powered the with TRS cable unless you are using a POD XT/X3 Live or Vetta) to the Line 6 Monkey, select your variax instrument, choose firmware (in the updates tab), and select “reinstall latest”.
