Control During Operation

In the other operating modes, manual adjustments are only accepted if the synchroni-
zation is momentarily lost. The messages “time error ON” and “time error OFF” are giv-
en when manually changing the year in the IRIG B mode.
Without healthy or external time synchronisation the free running date and time can
also be relatively
adjusted (+/– 23:59:59) using the entry field 'LII²WLPH.
This input possibility is not to be confused with the parameter 2IIVHW (see Section
5.7), which affects the specific general offset to the received synchronization time of
the radio clock receiver (e.g. local time vs. GMT time).
