how to check the region?
fgwp
E has a European plug, so I think it's pretty obvious what region it is
To remove it (basically doing a reset of the plug), on your A+ select to remove a Z-wave device (even when the plug isn't added to your A+ yet) and then triple-click the button on the plug.
Your A+ will then 'remove' it and the plug will reset.
Side note, this will NOT work when your A+ is not made for the EU-region.
