Checking normal operation
Before monitoring a patient, always check that the oximeter is operating normally.
WARNING: Patient safety. Never test or perform maintenance on the oximeter while
using it to monitor a patient.
WARNING: Failure of operation.
• Do not use the oximeter if it fails to function as described or if the validity of
data is questionable. Refer to the appropriate sections of this manual to
identify and correct the malfunction.
• It is possible for any device to malfunction; therefore, always verify unusual
data by performing a formal patient assessment.

illuminate briefly, then all turn off.

batteries as instructed in chapter 3.
