parasound remotes

Gentlemen;

If only out of a sheer lack of any info at all on Parasound equipment online, I find myself in dire need of help with my Parasound zpre2 and my newly acquired RM5 remote courtesy of parasound. It doesn’t seem to want to communicate with the preamp except to make the zone lamp light up red. I understand through what limited info I find online that the remote and the amp must be synchronized to the same zone, but nothing I do seems to accomplish this.

The instructions for the original remote don’t apply because the buttons are different and they don’t correspond. Does anyone know the secret to getting this remote taking to my preamp?

Mike
