About This Manual

The instructions in this manual are for the BM-850D and BM-850T. Before you start, please check your model number.

The main unit is the BM-850 for both the BM-850D and the BM-850T. You can use the BM-850D as a dictator since the BM-850D is supplied with accessories for dictating, while you can use the BM- 850T as a transcriber since the BM-850T is supplied with accessories for transcribing. Any differences in operation are clearly indicated in the text, for example, “BM-850D only”.

If you buy the accessories which your model does not have, your model works as both dictator and transcriber.
