7.2.3. Entries and changes using the operation panel
Changes on the device are always made in the following steps:
• Log into the device
• Complete and confirm the changes on the device
• Log out of the device
Use the Users main display to log in, confirm and log out  see section 7.3.11 System display Users
(Login/Logout / Password). The procedure for changing parameters is also described there.
Values which can be changed are displayed in white boxes. These are editable boxes. These editable
boxes appear depending on the login status and user rights. Changes are not finally entered and
saved to the device until the user has explicitly confirmed them. If the user has logged out
beforehand or is logged out due to another event without confirming the changes, any changes that
have been made will be discarded.

small gray box with a triangle next to the
value to be changed, in this example after
month and day.
The view will change when you click on it, in
the example the year.
