Perform a Self-Test (See “Performing the SpO2/Pleth Module Self-Test” on page 5-
43). If the SpO2/Pleth test numerics read exactly the listed values, proceed to the
next step, if not, replace the module.
6WHS
Refer to the following table. Correct the possible cause identified by the INOP
message and verify that the INOP disappears. If the problem still exists, replace the
module.

Patient movement or electrical
interference are causing irregular
pulse patterns. Make sure that patient does not move
strongly. If INOP persists, move cable
away from power cords.

not measure pulse rate.
Cover transducer against ambient light
