Please keep discussions of radiation safety serious. The XLt 898 contains a shielded X-ray tube (not a radioactive isotope, so no NRC license required in the US – but still dangerous). Never point it at people or animals. Always use the provided safety interlock (if your unit still has the rear connector – jumper pins 1 & 2 if missing).
I’ll watch for your Archive.org link. If anyone needs the in the future, reply here and I’ll forward the PDF once I have it.
