Key Operations Step By Step - Siemens ULTRAMAT 23 Series Equipment Manual

Operation
7.4 Operating modes
With the introduction of firmware version 2.15.06 of the basic device, you can now use letters
and special characters for the code in addition to numbers.
Note
You should change the factory-set codes once you have become acquainted with operation of
the ULTRAMAT 23 (see section Configuration: Special functions: Changing the codes/language
(Page 145)).
The lowest code level (level 1) is factory-set to "111", and the higher level (level 2) to "222".
The following are protected by code level 1:
• The dialogs "Logbook/faults" and "Maintenance requests" in the menu "Analyzer status",
submenu "Status",
• the menu "Calibration" ,
and
• the menu "Parameters".
The following is protected by code level 2:
• The menu "Configuration".
Note
If the analyzer requests that you enter code level 1, you can enter the code for level 2 instead to
release this level. Level 1 is then enabled simultaneously. Level 1 is automatically enabled as
soon as the higher code level 2 has been enabled.
Following input of a code, inputs are possible until the analyzer is recoded. If no input is
registered during a time period of 30 minutes, the analyzer automatically returns to the (coded)
measuring mode.
Note
In order to code the analyzer again when the input procedures have been finished (to protect
against unauthorized and unintentional interventions), press the <MEAS> key in measuring
mode.
