Hi Dave.
Thanks for posting on the forum.
Sorry to hear your having issues with your PRM-32 remote.
Have you tested other remotes from the same model of projector? Do they work first time or still intermittent?
I would recommend contacting Promethean technical support directly should you still have issues.
