6.3 Menu HISTORY INFO (IRDH375B)
99 events with date and time stamp can be stored in the memory database.
The database is designed as a ring memory, i.e. the eldest entry is overwritten.
Data is written into a non-volatile memory and therefore provides protection
against voltage failure.
Before storing the events with the actual date and time stamp, set the real-
time clock in the ISO ADVANCED menu (refer to page 59).
The following function keys are provided to query data from the
"HISTORY INFO" menu: the UP/DOWN keys to change the data record number,
the ENTER key to change from the data record number to the menu item
"Clear all:on" to delete the memory storage, and the ESC key to leave the
menu.
A new entry into the memory is signalled with an "H" on the display in the
standard mode. The "H" will be deleted as soon as the "HISTORY INFO" menu
is called up.
