In response the selected Alarm Masks Configuration Submenu screen is displayed.
You may want to begin by using the [8] All Alarms Control command to set all alarms
Reported or all alarms Masked, depending on how you intend to set the majority of the
alarm options. If you intend to change only selected items, go to step 4.

pears on the All Alarms Control current setting field. Before it’s highlighted the field can
display one three values: Masked, Reported, or Mixed. Masked and Reported are the values
to which you can set the field; Mixed is a display-only setting that the unit itself writes to
the field when it is appropriate. If Mixed is displayed before you select the option, it disap-
pears the first time you toggle the field.
3.
Use the arrow keys to toggle between the two potential settings, Masked and Reported, and
press the Enter key when the field displays your selected setting. The current setting fields
for all the individual alarms change to match your selection.
Go to step 9 if you don’t need to change any of the individual alarm options. If you do need
to change individual options, follow steps 4 through 8.

of Masked and Reported settings.
7.
Repeat steps 4 through 5 for each option you need to change.
