Tone codes?

I'm dropping off my Icom F5021 at a local shop for programming with the PCI Race Radio stock frequency list and the guy at the shop asked me about tone codes. I don't see it on the list and it is a new one to me. Is it something I"ll need to give him or is it not relevant for what we use the radios for?

mostly needed for repeaters. No tone needed for what youll use it for
