Access to the system with active access control (see section 4.3).
Access control is switched off in the delivery condition.
Every user can carry out all functions.
If access control for the DIQ/S 281 is active and the administrator password is
lost, rapid administrator access to the
DIQ/S 281 is no longer possible.
To avoid losing the administrator password, we recommend saving it. This also
applies to the use of the electronic key.
To save the administrator password, you can save it on an electronic key, for
example, and/or note it down on paper or on a PC. Keep the passwords in a safe
place.
If the DIQ/S 281 is locked and the administrator password lost, you
can unlock the system with a master password. Please contact the
service department.
The master password is valid for 7 days.
If you have unlocked the DIQ/S 281 with the master password, we
recommend to note down the normal administrator password and
keep it in a safe place.
