6.5.2 Erasing stored annunciations and counters --- address block 82
The statistical indications (Section 6.4.4, address
5600) are stored in EEPROMs in the device. They
are therefore not erased ifthe auxiliary powersupply
fails. Additionally, annunciations and the status of
the LED memories are stored in NV---RAMs and are
thus saved provided the back-upbattery isinstalled.
These stores can be cleared in block 82. Block 82 is
called up bypaging withthe keys Ý orß ordirectly by
keying inthe code DA 8 2 0 0 E.With the exception
of resetting the LED indications (address 8201), co-
deword entry isnecessary to erase thestored items.
Reset is separate for the different groups of count-
ers, memories and annunciations. One reaches the
individual items by paging " #. Erasure requires
confirmation with the key J/Y. The display then con-
firms the erasure. If erasure is not required, press
key N or simply page on.
