Bram, In Drager (Draeger) equipment the code is often related to the serial number so each piece of equipment has its own code. And the user manuals are often only issued to those who have been on the service course. This might not be true of every mode but just to warn you that it might be hard to come by the code and the manual. Can I presume you have searched Google and Frank's workshop manual site before posting here? best of luck in your hunt. Robert
My spelling is not bad. I am typing this on a Medigenic keyboard and I blame that for all my typos.
