Hello everyone,
I am a practicing audiologist (my own practice), and just recently bought an old Beltone "15CX Clinical Audiometer" for $50 on ****, just on a whim. I just got it, and it's in mint condition (almost), but I don't know how to operate it, since it's so old and uses the old "ISO-1964" standard. Two questions:
1. Does anyone know HOW this puppy works? I mean, I've tried to find a site that sells old manuals for obsolete stuff, but haven't turned up anything yet.
2. Can I still get the 1964 ISO standards CALIBRATED so that I could actually USE this machine? It's really in great shape, and is a "clinical" audiometer that would actually be useful to my practice in a pinch.

Any input out there?

PS I just joined this forum. I hope I'm doing this right.
