Hi Tony, I have very much a mish mash of NSM documentation but here is a copy of the ES/ES2 programming guide https://www.dropbox.com/scl/fi/w3qo9mq30ypmw398g94l4/ES___ES2_PROGRAMMING_GU... https://www.dropbox.com/scl/fi/w3qo9mq30ypmw398g94l4/ES___ES2_PROGRAMMING_GUIDE.pdf?rlkey=xp47yvi8xa1evdewgouocf0ez&st=r8xotzl9&dl=0 With regard to scanning once and not picking up, that usually indicates an opto problem (ie clean it!). You can also see it pulsing at the CCU with logic probe.

I'll have to read the manual better. I bought new ones that weren't programed and it acted the same as with a bad one. I think it scans once but doesn't pick up a record. If you happen to find that in the manual, I'd love to know where. On 4/18/2025 6:17 AM, NORMAN MACRAE via Jukebox-list wrote: > > It's an ER1400.
