I am presuming that all those asking for service manuals are aware that, on the Avea at least, the service menu can only be accessed after entering a password and that the password is unique for each device. Where I worked previously we were only able to obtain the service passwords for our machines via our local engineer, who had obtained them from Germany, after we had completed service training. There is also a separate manufacturer password and boy do things get interesting following hardware changes of any major assembly.
