yep i found it. I can take some pics tomorrow night if it helps.I found the section on changing battery ... other? . can send email to firstname.lastname@example.org ... i sent one asking if they had a soft copy.
I ran into the same issue a few years ago. It took Hendsoldt a few days to respond, but they sent me the user manual in PDF (actually, they sent the arabic one first by accident). I've attached it here since when I posted it in the past, I think we were still on the Scout site.
