Just bought a new TSN 883 and there doesn't seem to be any warranty papers with the item. I'm not sure if there should be any. I checked on their European website and it says the item has a 10 year warranty but there doesn't seem to be anywhere to register the product. I do have a receipt for the item so do you just contact them through their website if there is an issue and use the receipt as proof of purchase and date for any warranty issues? Just to add, I do not currently have an issue but would like to know for future reference.
