I wouldn't bother using the remote when you're typing the 568. Just use the front panel buttons.

As has been said you need to type your speakers ( you do need the remote for this) and select only one of them as master which you'll then connect to the 568 with a 5m lead. Once you've wired it only the master will respond to the clear command and allow you to set a single controller. The slave speakers will mirror the master speaker after this.

Good luck, it's worth it!
