WARNING: ENSURE THE UNIT HAS BEEN CLEANED PER THE
CLEANING INSTRUCTIONS IN SECTION 2.2.
5.2. General Procedures
5.2.1. Inspect the unit for cosmetic damage prior to disassembly or
troubleshooting. External damage may be helpful in
determining the root cause of the failure.

placed by the end user. Duplicate or transfer this information in
the event the housing or ancillary components are replaced.
5.2.3. Make note of the unit’s serial number.

5.3. Troubleshooting

needed to perform the Performance Verification in Section 4

evaluation purposes only and not to determine if an oximeter is “calibrated”.
