The Spectra system performs the tests in order. In each test, the
system moves valves and changes pump flow rates to create a
specific alarm condition. If the correct alarm occurs when the alarm
limit is reached, the Spectra system proceeds to the next alarm test.

screen appears:
ALARM TEST FAILED!
Press CONTINUE to retry alarm tests.
