Note
Synchronize reader time of day
Note that the reader clock corresponds to UTC time and cannot be adapted to time zones.
You can, however, transfer the local time of day stored in your operating system to the
reader. This time of day is retained on the reader for at least two days even without a power
supply. If the reader is disconnected from the power supply for a longer period, the time will
need to be reset. This can be done manually via the WBM, using NTP or in a program.
Later in the document, these symbols will help your orientation and will show you whether
the section is of interest to you or not. Only the sections with user-specific content, in other
words content that is tool/interface-specific contain these symbols. Sections without these
symbols are general and relevant for both areas of application.
