Chapter 4 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 International After-sale Dept.
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 Chapter 7 Disassembly Procedure 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 6.
