Do the stealth tutorial, which should be available at level 1 these days.

Pick up the guard's phone and look around. You should see some white outlines around the map for unused pager detectors, which you can see through walls as long as you're holding a guard's phone. You need to tap/hold the guard's phone against one of the unused detectors (green light / had a white outline) and it will resolve the condition.

Each location can only be used once. When a pager detector location has been used, it will be red and NOT have a white outline through walls.
