Safety

All users of the monitor must read and understand all safety information presented in this manual before using or repairing the monitor.

United States federal law restricts this device to sale, distribution, or use by or on the order of a licensed medical practitioner.

Warnings and cautions

WARNING Safety risk. Make frequent electrical and visual checks on cables, sensors, and electrode wires. All cables, sensors, and electrode wires must be inspected and properly maintained and in proper working order to allow the equipment to function properly and to protect patients.

WARNING Safety risk. Place the system and accessories in locations where they cannot harm the patient should they fall from a shelf or mount.

WARNING Fire and explosion hazard. Do not operate the system in the presence of a flammable anesthetic mixture with air, oxygen, or nitrous oxide; in oxygen-enriched environments; or in any other potentially explosive environment.

WARNING Inaccurate measurement risk. Dust and particle ingress can affect the accuracy of blood pressure measurements. Use the system in clean environments to ensure measurement accuracy. If you notice dust or lint build-up on the system’s vent openings, have the system inspected and cleaned by a qualified service technician.

WARNING Defective batteries can damage the device. If the battery shows any signs of damage or cracking, replace it immediately, and only with a battery approved by Welch Allyn.

CAUTION Before disassembling the device or installing options, disconnect the patient from the system, power down the device, and disconnect the AC power and any attached accessories (for example, SpO2 sensors, blood pressure hoses and cuffs, and temperature probes) from the device.

CAUTION To ensure that the system meets its performance specifications, store and use the system in an environment that maintains the specified temperature and humidity ranges.

Safety Welch Allyn Connex® Vital Signs Monitor 6000 Series™

CAUTION The system may not function properly if dropped or damaged. Protect it from severe impact and shock. Do not use the system if you notice any signs of damage.

CAUTION Do not connect more than one patient to a system or connect more than one system to a patient.

CAUTION Do not operate the system in the presence of magnetic resonance imaging (MRI) or hyperbaric chambers.

CAUTION Do not autoclave the system. Autoclave accessories only if the manufacturer’s instructions clearly approve it.

General safety considerations

• If the monitor detects an unrecoverable problem, it displays an error message. For more information see “Troubleshooting.”

• To ensure patient safety, use only accessories recommended or supplied by Welch Allyn. (See the accessories list on the user documentation CD or

www.welchallyn.com.) Always use accessories according to your facility’s standards

and according to the manufacturer’s recommendations and instructions. Always follow the manufacturer’s directions for use.

• Welch Allyn recommends that only Welch Allyn service personnel or an authorized repair center perform warranty service. Performing unauthorized service on a device that is within warranty may void the warranty.

Electrostatic discharge (ESD)

CAUTION Electrostatic discharge (ESD) can damage or destroy electronic components. Handle static-sensitive components only at static-safe workstation.

CAUTION Assume that all electrical and electronic components of the monitor are static-sensitive.

Electrostatic discharge is a sudden current flowing from a charged object to another object or to ground. Electrostatic charges can accumulate on common items such as foam drinking cups, cellophane tape, synthetic clothing, untreated foam packaging material, and untreated plastic bags and work folders, to name only a few.

Electronic components and assemblies, if not properly protected against ESD, can be permanently damaged or destroyed when near or in contact with electrostatically charged objects. When you handle components or assemblies that are not in protective bags and you are not sure whether they are static-sensitive, assume that they are staticsensitive and handle them accordingly.

Service manual Safety 7

• Perform all service procedures in a static-protected environment. Always use techniques and equipment designed to protect personnel and equipment from electrostatic discharge.

• Remove static-sensitive components and assemblies from their static-shielding bags only at static-safe workstations—a properly grounded table and grounded floor mat— and only when you are wearing a grounded wrist strap (with a resistor of at least 1 megohm in series) or other grounding device.

• Use only grounded tools when inserting, adjusting, or removing static-sensitive components and assemblies.

• Remove or insert static-sensitive components and assemblies only with monitor power turned off.

• Insert and seal static-sensitive components and assemblies into their original staticshielding bags before removing them from static-protected areas.

• Always test your ground strap, bench mat, conductive work surface, and ground cord before removing components and assemblies from their protective bags and before beginning any disassembly or assembly procedures.

Disassembly and repair

This chapter is divided into two major subsections, defined in the table below.

Section A Section B

(IEC 60601 3rd-edition compliant)

Devices meeting these criteria:

• Manufactured before 12/2017*

• MCE hardware version P3 or earlier (see the right pane on the Settings tab)

• Built before serial number* 100043244817

* See "Monitor serial number and model label" in the Appendix for serial number format and meaning.

Examine your device to determine which subsection you should follow to complete disassembly and repair procedures.

This overview includes exploded views of the rear housing and main chassis that include callouts referencing the parts. These exploded views apply to both Section A and Section B, though certain parts are labeled as specific to one section or set of devices and not the other. In the instructions, numbers in parentheses refer to callouts in the exploded drawings. Except where otherwise noted, the reassembly procedure is the reverse of the disassembly procedure.

Each part’s disassembly instructions may include one or both of the following subsections:

•

Reassembly notes: This contains information specific to reassembly not addressed in the disassembly instructions, especially when reassembly is not a simple reverse of disassembly.

• When replacing the component: This contains information specific to installing a new option or replacement part.

Devices meeting these criteria:

• Manufactured after 12/2017*
