Power-On: Setting of the internal clock after power-on
0 The internal clock is not set directly after power-on.
1 The internal clock is set directly after power-on, independent of the “lock“ status of the
reference time, i.e. eventually also by using a non-sync clock of a DCF77 or GPS
receiver.
2 After power-on the internal clock is only set, if the "lock" status of the reference time is
indicated. If the time operating mode is selected and no "lock" status is indicated within a
15 minutes period, this pre-set option is deactivated.
