Non-critical
Cause: The controller has flushed the cache
and any data in the cache has been lost. This
may happen if the system has memory or
battery problems that cause the controller to
distrust the cache. Although user data may have
been lost, this alert does not always indicate
that relevant or user data has been lost.

are functioning properly.

Cause: The controller battery is unable to
maintain cached data for the required period
of time. For example, if the required period of

normal to receive this alert during the battery
Learn cycle as the Learn cycle discharges the
battery before recharging it. When
discharged, the battery cannot maintain
cached data.
Action: Check the health of the battery. If the
battery is weak, replace the battery pack.
