How to setup speakers to zone 2 on a B&K AVR202

Can anyone please tell me how to setup speakers on the 2nd zone of my B&K AVR202? It has zone outputs and line outputs and I'm not sure how to set it up. I am trying to run two outdoor speakers for around the pool and want to be able to play my iTunes music through my received on the 2nd zone to the outdoor speakers. I know I am doing something wrong because first of all I have two speaker wires and only one output for zone 2 on either the zone or line, so that right there tells me something is off, but just not sure what I am supposed to do. Any help would be greatly appreciated!!!

Thanks a lot,
