requests, click
or to select the next or previous action request
.
• Once you initiate an answer, the and buttons are desensitized.
• To cancel an answer, select

When the database is locked during OSx station synchronization, the
operator needs to be aware of the following points concerning action
requests.
•
During OSx station synchronization, the operator cannot access action
requests from any station. If an operator attempts to access an action
request while the database is locked, the system displays a message
indicating that the summary cannot be accessed while the database is
locked.
If an operator has displayed the summary before the system locks the
database, and then pressed the
Commit
button, the system does not
commit the answer until after the database is unlocked. The system
does not process any further action request selections until after it
unlocks the database.
• The action request button appears on all OSx stations except the
primary and the station that is synchronizing.
• The action request button appears on the primary for new alarms and
action requests after the system unlocks the database.
