Using windows explorer, look in:
c:\progam files\respironcis\Encore Pro\Utilities
There are to files with an .reg extension:
Erase data after download.reg
Don't erase data after download.reg
Double clicking either of these files will setup your encore pro to erase or not erase the data from the card after downloading. You can run either of these files as much as you want without any risk to your registry.
Hope this is what you guys are talking about.
