Panafax remote diagnostic feature software registration code

[Electrictoner]

I just got on service about 50 Models UF-595-6000 (mostly 6000) of these and am charging by click. Have any of you ever used remote diagnostics to retrive the meters? I found some info on it "see your panasonic dealer" for the software registration code for the Remote Diag program. Has anyone ever used this feature or have the/a reg code for the software I could use?
I just trying to not have to go to the various sites every month to get the billing info
Any input or help would be appreciated
Thanks
Billy

If they are using it a fax, you can setup check & call feature on them. It is in service mode.
