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.
