"At one point in my career I ended up as the Technical Manager for the group within Philips that supported this gizmo.

(I remember how I found that out too - one day I found a stash of them in a store cupboard, and called the Philips Support main product support line to see if they could put me through to the tech support for it. Every time I tried it was busy, so after 3 or 4 attempts I asked if I could have the name and number, which they wouldn't normally give, but since it was an internal call, they trusted me. They gave me my own name and number...)

I've got a copy of the English user manual, and I'm happy to take requests for individual copies until I can get it scanned in and PDF'd. If there's enough demand I can do that over the coming holidays."
