Chapter 4 Troubleshooting Guide
4.1 Introduction
The troubles we list in this chapter frequently raise difficulties regarding the patient monitor and the actions we
recommend can correct most problems, but not all of them. For more troubleshooting information, contact our
service department.
4.2 Part Replacement
PCBs, Major parts and components in the patient monitor are replaceable. Once you isolate a PCB you suspect
is defective, follow the instructions in “Assembly and Disassembly” to replace the PCB with a known good one
and check whether the performance of the monitor is restored. If the trouble remains, exchange the replacement
PCB with the original suspicious PCB and continue troubleshooting as directed in this chapter. A defective PCB
can be sent to us for repair.
