If the optional battery is not installed, the alarm history record data will be initial-
ized when the PT’s power is turned OFF.
Initialize the alarm history record data by following the menu operations from the
Maintenance Mode Menu as shown below.
Select Memory Init..
Select Alarm History.
Select Yes.
The alarm history record data is initialized.
During initialization, the message Initializing
is displayed.
If No is selected, the NT21 returns to the MEMORY INIT. MENU screen without
initializing the alarm history record data.
On completion of alarm history record data initialization, the message Finished
is displayed and the NT21 returns to the MEMORY INIT. MENU screen.
6-4-4 Initializing the Memory Tables
It is possible to initialize the numeral memory table and character string memory
table in the NT21.
When these tables are initialized, the values are returned to those set by the NT
Support Tool (they are not cleared).
When the memory tables are initialized, they are returned to their initial values
regardless of the setting made for the resume function (page 140).
If ON is set for the Resume Function memory switch, the initial values set with
the NT Support Tool will not be recorded in the memory tables unless they are
initialized.
