PA1 label again.

ter inside "diS" folder, not to be confused
with PA2 label inside "CnF" folder.
If specified, level 2 parameters are hidden
to user; accessing the "CnF" folder the
level 2 access PASSWORD will be request-
ed and (if the correct password is entered)
the label of the first folder in the pro-
gramming menu will follow.

tioning on regulation and delay time
occuring.

parameters. In the standard configuration
passwords are not present. To enable

menu, within the folder with the "diS"
label. If passwords are enabled, they will
be requested:

label containing level 1 parameters.
