Does anyone have the service manual for the Vitalograph Alpha Model 6000 spirometer. I have a number of units that have a warning screen flashing up saying that the unit needs to be serviced. Is there a way to get this warning cleared without paying Vitalograph £215.00 to do so.

The Service manual does not tell you how to remove this service date. After querying it with the manufacturer the only way of removing this is for it to be done by them. (business eh!)
