2.3.1 Changing values
The methods of entering and changing values differ depending on the value. These are
therefore subdivided into so-called "data classes" (abbreviation: "DC"). Values in the same
data class are treated identically during entry. A prerequisite for an entry is that the lock
assigned to the value is open.
The following data classes (DC) are present in the EK220:
DC
Type Entry, change using "ENTER"
1 Display test No change possible.
2
Function Triggers the function by entering "1".

With an open lock, the combination is changed by the entry.

class by the keypad, since the key <ENTER> is then used for branching into the submenu.
