Q1
Close
All defined locks are closed.
This menu item appears being crossed out and is thus not selectable
if all locks are closed. If the calibration switch is open, all locks are
automatically open, too, and cannot be closed.
Set clock
Activate this menu item to adjust the internal device time.
You may re-enter time and date step by step via the numerical keypad in the
edit mode, i.e. after you have pressed the Enter key.
The time zone menu item offers a selection list (
summer/winter time
) for you to
choose the seasonal time zone as soon as you are in the edit mode.
However, it is also possible to operate the device throughout the year without a
seasonal time change. The seasonal time change can be prevented by
parameterisation. In such a case, the phrase
not used
appears next to
Time
zone
, and it is not possible to change to the edit mode here.
After having set the time correctly, invoke the menu. Return to the main display
without accepting the new time adjustment via
Cancel
. You may only confirm
your setting via
OK
if the acceptance of the new time is permissible

Display test
You may check whether or not the display and status LED function correctly by
performing the display test. After you have activated the
Display test
menu item,
the pixels of the display are alternately switched on and off. At the same time
the status LED shows all three colours after each other. Finish the display test
via
Back
