Troubleshooting
4.1 Introduction
In this chapter, patient monitor problems are listed along with possible causes and
recommended corrective actions. Refer to the tables to check the patient monitor, identify and
eliminate the troubles.
The troubles we list here are frequently arisen difficulties and the actions we recommend can
correct most problems, but not all of them. For more information on troubleshooting, contact
our Customer Service Department.
4.2 Part Replacement
Printed circuit boards (PCBs), major parts and components in the patient monitor are
replaceable. Once you isolate a PCB you suspect defective, follow the instructions in
Repair
and Disassembly
to replace the PCB with a known good one and check that the trouble
disappears or the patient monitor passes all performance tests. If the trouble remains,
exchange the replacement PCB with the original suspicious PCB and continue
troubleshooting as directed in this chapter. Defective PCB can be sent to us for repair.
To obtain information on replacement parts or order them, refer to
Parts.
