self-test, the audible alarm emits a slow modulating tone and
the visual alarm flashes slowly. Sensor fail display advises
failed sensor:
Self-Test Pass
If the detector passes the self-test, the detector begins
normal operation. The display shows the ambient gas
readings:
The detector starts recording the maximum gas exposure
and calculating the TWA (time-weighted average).
Self-Test Fail
If the detector fails the self-test, see the section, “If the
Detector Does Not Work.”
