Creating a backup of bike controller settings

[bmwgser]

Hi. 

I have just bought the GS-911 wifi and got it working with my R1250GS and my iPhone.  I have seen advice in different places that it is a good idea to make a backup of the bike settings before changing anything so that the settings can be restored to known working values if anything should go wrong.  However, I cannot find out how to do this.  There is nothing in the User Manual about doing this.  I have reviewed the operating menus on my iPhone and tried to search this forum but no luck. 

I would much appreciate it if someone could explain how this is done and how to restore from a backup if this should be necessary. Many thanks.
