Is there a way to reset back to English language on Grundig GU19WDVD10?

4 year old daughter has somehow changed the language to what looks like arabic on her elder sisters TV...as the set up menu is now in arabic i do not know where to start to change the language back to English. is there a simple way of doing this ie putting it back to factory settings or can someone who has similar TV talk me through screen by screen as i am not expert in Arabic!? Thank you
