4 Testing and Maintenance
4.1 Introduction
To ensure the patient monitor always functions properly, qualified service personnel should perform regular inspection,
maintenance and test. This chapter provides a checklist of the testing procedures for the patient monitor with
recommended test equipment and frequency. The service personnel should perform the testing and maintenance
procedures as required and use appropriate test equipment.
The testing procedures provided in this chapter are intended to verify that the patient monitor meets the performance
specifications. If the patient monitor or a module fails to perform as specified in any test, repairs or replacement must be
done to correct the problem. If the problem persists, contact our Customer Service Department.
CAUTION
 All tests should be performed by qualified service personnel only.
 Care should be taken when changing the settings in Maintenance and Configuration menus to avoid loss
of data.
 Service personnel should possess a working knowledge of the test tools and make sure that test
equipment and cables are applicable.
