Warranty question

Hey guys.
I just have a question about warranty.
Do I need to send the yellow slips in? I have an extra two years warranty from Harvey Norman... what exactly do I need if something goes wrong in about two years? Just provide proof of purchase and the warranty information?
Thanks.
Owen.
