Playbar with one play:1 remote control problem

Hi,

I just bought myseld the playbar in combination with only one play:1. I could only set his up as stand alone speaker in other room and group together, but now the remote control only works with the playbar, while the play:1 not responds on the remote control. Any help with this?
- how to setup playbar with one play:1 in same room
- use remote control for both

Cheers!
