Operation Manual SUPREMA
4. Operation of the System
After an output number is selected, the rest of the menu is filled, if settings have already been
entered for that output. This input field can be accessed without a key switch or password if an
output is entered for which parameters have already been set. If a number is entered that has
not been used before, authorisation by means of password or key switch is required.
This makes it easy to copy the settings from one input to another. If an input is displayed that
has not yet been configured, default values are use as the preliminary settings for the input of
the certain fields.
This selection field can be accessed without a key switch or password if an input is entered for
which input parameters have already been set. If a number is entered that has not been used
before, authorisation by means of password or key switch is required.
