As the password needs to be generated by Viasys (now Zoll in Europe) using the following information:

1. The facility Name.
2. The S/N of the Unit and UIM.
3. The current Configuration of the unit (HELIOX, COMPRESSOR.

I dont see how this can be accessed.

Maybe someone with a password and the above information can reverse engineer the PW but its a long shot I think.
.
Here in Italy you have to open a job ticket and even then they will not supply the PW.
