8.1

Overview

This chapter describes how to troubleshoot common problems while using the 
Nellcor™ Bedside SpO

2

 Patient Monitoring System.

8.2

General

WARNING:
Check the patient's vital signs by alternate means should there be any doubt 
about the accuracy of any measurement. Request a qualified service 
technician confirm the monitoring system is functioning correctly.

WARNING:
Only a qualified service technician should remove the cover or access any 
internal components. 

If the monitoring system detects an error, it displays an appropriate error code. 
The 

Service Manual

 lists all error codes. If an error occurs, check and reseat all 

power connections and ensure the battery is fully charged. If the error persists, 
write down the error code and contact Technical Services or a qualified service 
technician.
