1 Introduction
1.1 Overview
This manual, for use by qualified personnel only, contains instructions for
servicing, testing, and maintaining the Nellcor™ Bedside Respiratory Patient
Monitoring System.
This manual applies to the following products:
1.2 Intended Audience
This manual provides information to professionals acting as trained and quali-
fied service technicians in a hospital or hospital-type setting for maintenance
and service or repair of the monitoring system. Refer to the institution for any
additional training or skill requirements beyond those identified here for main-
tenance and repair of the monitoring system. Before servicing, thoroughly read
this manual.

1.3 Safety Information
1.3.1 Safety Symbols
1.3.2 Warnings
WARNING:
Explosion hazard — Do not use in the presence of flammable anesthetics.
WARNING:
Shock hazard — Use only when connected to a grounded outlet to avoid
electric shock.
WARNING:
Before attempting to open or disassemble, disconnect the power cord to
avoid possible injury.
WARNING:
Use only Covidien-approved internal batteries.
WARNING:
The monitoring system is not defibrillator-proof. It may remain attached to
the patient during defibrillation or during use of an electrosurgical unit,
Table1-1.Safety Symbol Definitions
Symbol Definition
WARNING
Warnings alert users to potential serious outcomes (death, injury, or adverse
events) to the patient, user, or environment.
Caution
Cautions alert users to exercise appropriate care for safe and effective use of
the product.
Note
Notes provide additional guidelines or information.

Safety Information
Service Manual 1-3
however, readings may be inaccurate during use in this environment and
shortly thereafter.
WARNING:
Supplemental oxygen will attenuate patterns of desaturation. A patient’s
respiratory compromise can be proportionally more severe before patterns
appear in the saturation trend. Remain vigilant when monitoring a patient on
supplemental oxygen.
WARNING:
Do not silence or disable audible alarms or decrease the volume of the audible
alarm if patient safety could be compromised. Do not dim or disable visual
alarms if patient safety could be compromised.
WARNING:
Ensure the monitoring system is clear of any obstructions that prevent
awareness of visual or audible alarms. Failure to do so may result in
inadvertently missing a visual alarm or an inaudible alarm tone.
WARNING:
Do not use any monitoring system, sensor, cable, or connector that appears
damaged. Remove any damaged equipment from service for inspection by a
qualified service technician.
WARNING:
Do not lift by the sensor or interface cable. The cable may disconnect,
potentially dropping the monitoring system on a patient or damaging
surface.
WARNING:
When installing the AC power cord, ensure the cord is carefully positioned to
prevent tripping and entanglement.
WARNING:
Do not spray, pour, or spill any liquid on the monitoring system, its accessories,
connectors, switches, or openings in the chassis, since this may cause damage
to the monitoring system.

Introduction
1-4 Service Manual
WARNING:
To ensure accurate performance and prevent device failure, do not subject to
extreme moisture, such as direct exposure to rain. Such exposure may cause
inaccurate performance or device failure.
WARNING:
The monitoring screen contains toxic chemicals. Do not touch a broken
enclosure or monitoring screen. Physical contact with a broken enclosure or
monitoring screen can result in transmission or ingestion of toxic substances.
WARNING:
No user serviceable parts inside.
1.3.3 Cautions
Caution:
Federal law (U.S.A.) restricts this device to sale by or on the order of a
physician.
Caution:
When connecting the monitoring system to any instrument, verify proper
operation before clinical use. Both the monitoring system and the instrument
connected to it must utilize a grounded outlet. Any equipment connected to
the data interface must be certified according to the latest IEC/EN 60950 -1
standard for data-processing equipment, the latest IECEN 60601-1 standard
for electromedical equipment, or the latest IEC/EN safety standards relevant
to that equipment. All combinations of equipment must be in compliance
with Requirements for Medical Electrical Systems IEC Standard
60601-1:2007and the electromagnetic compatibility IEC/EN Standard
60601-1:2005. Anyone who connects equipment to the data interface is
configuring a medical system and, therefore, is responsible for ensuring that
the system complies with the Requirements for Medical Electrical Systems
IEC/EN Standard 60601-1-1:2007 and the electromagnetic compatibility IEC/
EN Standard 60601-1-2:2007. Accuracy may degrade if it is connected to
secondary I/O devices when the equipment is not connected to earth
reference.

Obtaining Technical Assistance
Service Manual 1-5
Caution:
Observe electrostatic discharge (ESD) precautions prior to opening the chassis
or handling any internal components.
Caution:
Observe the required torque for tightening screws. Over-tightening can strip
out screw holes, rendering them useless.
1.4 Obtaining Technical Assistance
