Measurement validation
The SpO2 accuracy has been validated in human studies against arterial blood sample
reference measured with a CO-oximeter. Pulse oximeter measurements are statistically
distributed, and only about two-thirds of the measurements can be expected to fall within
the specified accuracy compared to CO-oximeter measurements.
NOTE
The SpO2 simulator can only be used to verify that the pulse oximeter
operates properly. It cannot be used to verify the accuracy of the pulse
oximeter or the SpO2 sensor. To verify the accuracy, clinical tests are
required.

6 Disassembly and Repair
6.1 Tools Required
To disassemble and replace the parts and components, the following tools may be required:
Philips screwdrivers
Tweezers
Sharp nose pliers
Clamp
6.2 Preparations for Disassembly
Before disassembling the equipment, finish the following preparations:
Stop monitoring, turn off the equipment, and disconnect all the accessories and
peripheral devices.
Disconnect the AC power source and remove the battery.
WARNING
Before disassembling the equipment, be sure to eliminate the static charges
first. When disassembling the parts labeled with static-sensitive symbols,
make sure you are wearing electrostatic discharge protection such as
antistatic wristband or gloves to avoid damaging the equipment.
Properly connect and route the cables and wires when reassembling the
equipment to avoid short circuit.
Select appropriate screws to assemble the equipment. If incorrect screws are
tightened by force, the equipment may be damaged.
Follow correct sequence to disassemble the equipment.
Be sure to disconnect all the cables before disassembling any parts. Be sure
not to damage any cables or connectors.
Place the screws and parts from the same module together to facilitate
reassembling.
To reassemble the equipment, first assemble the assemblies, and then the
main unit. Carefully route the cables.
Ensure all gaskets and seals are correctly installed during reassembly.

7 Parts
7.1 Introduction
This section contains the exploded views and parts lists of the main unit. It helps the
engineer to identify the parts during disassembly of the monitor and replacing the parts.
This manual is based on the maximum configuration. Your equipment may not have some
parts and the quantity of the screws or stacking sleeves etc. may be different with those
included in the parts lists.
NOTE
For parts in the Parts List below that contain two part numbers, the first part
number is for patient monitors built with one version of plastic material, the
second part number is for patient monitors built with another version of
plastic material. The way to distinguish which material your monitor is built
from is if it contains the symbol

A Electrical Safety Inspection
The following electrical safety tests are recommended as part of a comprehensive
preventive maintenance program. They are a proven means of detecting abnormalities that,
if undetected, could prove dangerous to either the patient or the operator. Additional tests
may be required according to local regulations.
All tests can be performed using commercially available safety analyzer test equipment.
Please follow the instructions of the analyzer manufacturer.
The consistent use of a safety analyzer as a routine step in closing a repair or upgrade is
emphasized as a mandatory step if an approved agency status is to be maintained. The
safety analyzer also proves to be an excellent troubleshooting tool to detect abnormalities
of line voltage and grounding, as well as total current loads.
