inlet. After 10 seconds, the pump shuts off and
the “Occlusion” pop-up window displays.
2. Remove the finger and press

moisture trap is not inserted properly.
4. Remove and reinsert the moisture trap in the
monitor.
5. Repeat occlusion test.
The monitor has an internal
air leak.
Verify that there is not an internal leak to the
pump by creating an occlusion:

2. Using a finger, cover the small
hole in the recessed area of
the monitor (see arrow in
