Objectives
In order to meet this chapter’s objectives, you should be able to perform light maintenance
and preventive maintenance for the Monitor, the Measurement Server and, where present, the
Measurement Server Extension through the following tasks:
• Inspection of the Instrument.
• Cleaning of the Instrument.
• Replacement of Preventive Maintenance Parts
• Battery Handling, Maintenance, and Good Practices.
This chapter provides an overall maintenance frequency timetable as well as a checklist of
maintenance procedures which include, for the sake of completeness, comprehensive
reference to the repair procedures found in "Repairing the Instrument" and to the testing
procedures found in "Testing the Instrument".
The tests included in "Testing the Instrument" are functionality assurance tests, performance
assurance tests (preventive maintenance tests), accuracy and performance procedures, and
patient safety checks used to verify that the Instrument is operating properly.

A rechargeable battery must be conditioned at regular intervals to prepare it
for further charge/discharge cycles. Conditioning a battery refers to the
complete discharge of a charged battery by allowing it to die out while in
non-critical use. The empty battery may then be recharged and put back into
use.
