Safety
User responsibility
• The numerical and graphical results and any interpretation given must be examined
with respect to the overall clinical condition of the patient and the general recorded
data quality.
• The indications given by this equipment are not a substitute for regular checking of
vital functions.
• This monitor is only to be used by those trained in its operation or repair.
• Ensure that the personnel have read and understood these operating instructions and
in particular this “Safety” section.
• Damaged or missing components must be replaced immediately.
• It is the owner's responsibility that the valid regulations for safety and prevention of
accidents are observed.
Intended use
• The Welch Allyn® 1500 Patient Monitor patient monitoring unit is designed for the
monitoring of vital parameters such as ECG, SpO
pressure (NIBP), invasive blood pressure (IBP), temperature and respiration of a
patient. Cardiac output and hemodynamic calculations are also possible.
• The device is intended to be used by qualified doctors or trained medical personnel.
• The device is not suitable for transport.
• There is no danger for patients with pacemaker.
• The device is intended for the monitoring of one patient at a time.
• The device is not designed for sterile use nor is it designed for outdoor use.
• Do not use this monitor in areas where there is any danger of explosion or in the
presence of flammable gases.
• The device is classified CF. It is defibrillation protected when the original
accessories are used. However, as a safety precaution when possible, remove the
electrodes before defibrillation.
• This product is not designed for direct cardiac application.
• The arrhythmia module is not intended for use with neonatal patients.
• The ST-analysis module is not intended for use with neonatal patients.

Organizational measures
• Before using the monitor, ensure that an introduction regarding the monitor functions
and the safety precautions have been provided by a medical product representative.
• Observe the operating instructions and maintenance instructions.
• These operating instructions do not override any statutory or local regulations, or
procedures for the prevention of accidents and environmental protection.
Safety
WARNING Mount the monitor securely so that there is no possibility of it falling
on the patient or on the floor.
WARNING If uncertain about the accuracy of any measurement, first check the
patient’s vital signs by alternate means, and then make sure the monitor is
functioning correctly.
WARNING Do not touch the monitor during defibrillation.
WARNING To ensure patient safety, none of the ECG electrodes including the
neutral electrode, nor the patient or any person with simultaneous patient
contact, must come in contact with conductive parts, even when these are
grounded.
WARNING If you notice any changes that impair safety (including operating
behavior) remove the monitor from service and report it to the person responsible
for servicing the monitor.
WARNING Do not place any liquids on the monitor. If liquid is spilled over the
monitor, immediately disconnect the monitor from the mains and dry. The
monitor must be serviced before reusing.
Caution This manual, and especially these safety notes, must be read and
observed.
Caution Electrical installation of the room or the building in which the monitor is
to be used must comply with regulations specified by the country in which the
equipment is to be used
Caution Ensure the monitor is always mounted on a Welch Allyn approved
bracket or stand. The monitor is unstable when the unit is not secured to an
approved Welch Allyn mounting system.
Directions for use Safety 3
Safety equipment
Operating the monitor without the correctly rated fuse, or with defective cables,
constitutes a danger to patient safety. Therefore:
Caution Do not operate the monitor if the ground connection is suspect or if the
mains lead is damaged or suspected of being damaged.
Caution Damaged cables and connections must immediately be replaced.
Caution Electrical safety devices, such as fuses, must not be modified.
Caution Fuses must only be replaced with the same type and rating as the
original.
Alarms
WARNING Do not silence the audible alarm if patient safety could be
compromised.
WARNING Always respond immediately to an equipment alert because the
patient may not be monitored during certain alarm conditions.
WARNING Before each use, verify that the alarm limits are appropriate for the
patient being monitored.
WARNING Check the audible alarm silence duration before temporarily silencing
the audible alarms.
4 Safety Welch Allyn 1500 Patient Monitor
Operation with other devices
Caution Do not use the monitor in or near an MRI suite.
• Only use accessories and other parts recommended or supplied by Welch Allyn. Use
of other than recommended or supplied parts may result in injury, inaccurate
information or damage to the monitor.
• Accessory equipment connected to the analogue and digital interfaces must be
certified according to the respective IEC standards (e.g. IEC/EN 60950 for data
processing equipment and IEC/EN 60601-1 for medical equipment). Furthermore all
configurations shall comply with the current version of the system standard IEC/EN
60601-1-1. Anyone who connects additional equipment to the signal input part or
signal output part configures a medical system, and is therefore responsible that the
system complies with the requirements of the valid version of the system standard
IEC/EN 60601-1-1. If in doubt, consult the technical service department or your local
representative.
• Any other equipment used with the patient must use the same common ground as
the monitor.
• Precautions must be observed when using high frequency devices. Operating high
frequency electro-surgical equipment in the vicinity of the monitor can produce
interference in the monitor and cause incorrect measurements. Only use patient
cables recommended by Welch Allyn to avoid possible signal interference during ECG
acquisition.
• There is no danger when using the ECG monitor simultaneously with electrical
stimulation equipment. However, during defibrillation, keep discharge paddles away
from the monitor ECG lead wires, electrodes, any other monitor sensors, and other
conductive parts in contact with the patient.
• If the patient cable should become defective after defibrillation, a lead-off indication is
displayed and an audible alarm is issued.
• Portable communication equipment, HF two-way radios and devices marked with the
symbol can affect this monitor (see “EMC compliance” on page 98).
Networks and internet
• When the monitor is part of a network, (LAN, HIS, etc.), transmitting over a telephone
network or any other transmission /reception medium, or if exposed to the Internet or
other networks that are not secure, appropriate security measures must be provided
to protect the patient information stored.
• Patient security and security of the network is the sole responsibility of the user.

Caution Do not use high temperature sterilization processes (such as
autoclaving). Do not use E-beam or gamma radiation sterilization.
Caution Do not use solvent or abrasive cleaners on either the monitor or cable
assemblies.
Caution Do not immerse the monitor or cable assemblies in liquid.

Commission) rules and the radio interference regulations of the Canadian
Department of Communications. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with this instruction
user guide, may cause harmful interference to radio communications. Operation
of this equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own
expense.
WHEN USED IN CANADA: To prevent radio interference to the licensed service,
this device is intended to be operated indoors and away from windows to provide
maximum shielding. Equipment (or its transmit antenna) that is installed outdoors
is subject to licensing.

Battery operation
Two batteries are available for the monitor:
• Lithium-Ion battery: This type of battery will provide power for approximately two
hours when fully charged.
