I recently purchased a brand new D-Light Sync Pak for home use and I think it's awesome! I do have one issue with it, though. It seems the mechanism inside squeaks. This occurs in both fixtures. That is, when the mechanism moves, it squeaks...like it needs lubrication or something.
The manual says there are no user-serviceable parts, inside, but it would seem to me that some silicone lubricant should fix the problem.
Has anyone had this issue, before? Any suggestions, besides making the music louder? LOL
