Using the Medical/Emergency button

Emergency buttons only work when a computer knows its location. At each workstation where the emergency buttons are inactive, go to Menu>User and Location. You should see a drop-down menu under Location Settings. Choose the corresponding location of the computer, be sure to Save, and then you can test the button to make sure that it has been properly activated.

The emergency button (High Alert button) can only be cleared at the location where it was activated as  well,  if you ever have one that turns on but no one can figure out why it's not shutting off. On newer versions, you can shut off the High Alert button from the System Manager by choosing Menu > Clear All Active High Alerts.
