It is indeed an Ericsson branded Psion. Cool project. I wonder if those frequencies will become open once they discontinue them for regular cell transmission.

Ohh you… That’s very nice of you to say.

No I don’t work with writing documentation, but I’ve found that often times the "how to’s " miss the explanation part between steps, or don’t show enough examples for novices. Understanding what you are doing is sort of the point, and not adding context will make it harder for the reader to navigate any roadblocks that they may encounter. A step by step instruction shouldn’t leave you stuck on a step because the writer expects that you know how to navigate or find a specific menu. Unless it is explicitly stated of course. I don’t expect expert level documentation to also go through all the basics.
