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 monitor 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 monitor 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 monitor in clean environments
to ensure measurement accuracy. If you notice dust or lint build-up on the monitor’s
vent openings, have the monitor inspected and cleaned by a qualified service
technician.
Caution To ensure that the monitor meets its performance specifications, store
and use the monitor in an environment that maintains the specified temperature and
humidity ranges.
Caution The monitor may not function properly if dropped or damaged. Protect it
from severe impact and shock. Do not use the monitor if you notice any signs of
damage.
Caution Do not connect more than one patient to a monitor or connect more than
one monitor to a patient.
Caution Do not operate the monitor in the presence of magnetic resonance
imaging (MRI) or hyperbaric chambers.
Caution Do not autoclave the monitor. Autoclave accessories only if the
manufacturer’s instructions clearly approve it.
3

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
“VSM 6000 series approved accessories” in the Welch Allyn Vital Signs Monitor 6000 Series
Directions for use (part number 103501)). 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 static-sensitive and handle them accordingly.
• 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 static-shielding
bags before removing them from static-protected areas.
4Safety Welch Allyn Vital Signs Monitor 6000 Series™

• 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.

The Welch Allyn Service Tool
The Welch Allyn Service Tool is available in the following editions:
•Silver: Accompanies your monitor.
•Gold: Required to perform functional verification. This edition requires an additional license.
For more information about acquiring this license, contact Welch Allyn.
Note To qualify for the Gold license, you must attend the Welch Allyn
technical training course or complete online training for the Welch
Allyn VSM 6000 Monitor Series.
Clinicians and technical service personnel can use the service tool to manage and maintain
supported Welch Allyn products. You can use the service tool to do the following:
•Review monitor information. When connected to the monitor, the service tool lists
installed modules, installed firmware and hardware versions, warranty and repair information,
status, and usage history.
•Receive notifications when periodic maintenance is needed. The service tool can
help you manage and maintain your entire inventory of supported Welch Allyn products.
Through the remote service function, the service tool can connect to Welch Allyn Customer
Service. With this functionality you can automatically receive firmware updates and feature
upgrades for your supported products, including software upgrades for the service tool.
•Install updates and upgrades. The service tool can read the firmware version for each
module and check for available updates or upgrades.
Service manual Overview 13

•Create a work list. The work list provides information about service actions—referred to as
work orders—that are waiting for you to perform on your maintained devices. Work orders
may include periodic calibrations, upgrades, or license installations.
•Schedule periodic maintenance. You can use the service tool to set the service interval
for each maintained device.
•View and save logs. You can download and save log files from the device for analysis to
help diagnose and identify reported issues.
•Create user accounts. Administrators can create user accounts and set permission levels
to control access to the features, allowing one group to perform administrative tasks and
another to perform service tasks. Restricting access prevents the service tool from being used
to make unauthorized changes on a connected device.
•Perform functional verification. You can use the service tool to test each component of
the system to ensure that its performance meets design specifications. Functional verification
is required to meet the periodic maintenance requirements. This feature is not supported for
all products and requires the service tool Gold edition for each supported product.
•Perform calibration verification. The service tool can check any system requiring
calibration and, if necessary, calibrate the monitor to match the design specifications.
Calibration verification is required to meet the periodic maintenance requirements. This
feature is not supported for all products and requires the service tool, Gold edition, for each
supported product.
•Recover devices. In the rare case where a device can no longer boot because of corrupted
firmware, the service tool can connect the device to Welch Allyn Technical Support to
reinstall the firmware.
•Extensible. The monitor accepts new plug-ins to support future Welch Allyn products.
Some of these features are enabled for any user (Silver edition). Others require special user
account privileges or a Welch Allyn service contract (Gold edition). If you require gold-level
support for a Welch Allyn product, please contact Welch Allyn technical support.
Battery performance
About the battery
The monitor uses a rechargeable lithium ion smart battery. Internal circuitry enables the battery to
report its condition to the monitor. The monitor displays the battery status via the LED power
indicator, icons on the screen, and status messages appearing in the Device Status area of the
display. Battery information may be collected using the service tool.
New batteries are shipped from the manufacturer with a 30 percent charge to extend shelf life.
When installing a new battery in the monitor, you must plug the monitor into AC power to wake up
the battery. If the AC power is not applied to the monitor, the new battery will appear discharged.
The Device Status area displays a low-battery status message when 30 minutes of power remain
and again when 5 minutes remain.
You can expect new, fully charged batteries to have enough power for the following:
• Six-cell batteries provide approximately 26 patient exams.
• Nine-cell batteries provide approximately 47 patient exams.
Note A patient exam includes NIBP, temperature, and SpO2 measurements at the rate of
one patient every 10 minutes with a 2 minute display timeout setting with a new
battery, conducted at room temperature (72.5 °F ±4.5 °F; 22.5 °C ±2.5 °C).
14 Overview Welch Allyn Vital Signs Monitor 6000 Series™

The number of exams per charge decrease with the battery age.
Depending on the age of the battery, a 6-cell battery takes 3 hours and a 9-cell battery takes 4
hours to fully charge at room temperature.
Both batteries have a lifetime of 300 charge cycles or more, where a charge cycle is equal to fully
charged to discharged to fully charged at room temperature.
Battery charging is provided by the monitor’s internal power supply.
For a complete list of battery specifications, see the Welch Allyn VSM 6000 Series Directions for
use (part number 103501).
Best practices
The following practices help to extend the life of the battery and the monitor.
WARNING Safety risk. When handling and storing Lithium batteries: Avoid
mechanical or electrical abuse. Batteries may explode or cause burns, if
disassembled, crushed or exposed to fire or high temperatures. Do not short or
install with incorrect polarity.
• Remove the battery when storing the monitor.
