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

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

General safety considerations

• To ensure patient safety, use only accessories recommended or supplied by Welch
Allyn. 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
device 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

6 Safety CP 150 12-lead resting electrocardiograph

bags and you are not sure whether they are static-sensitive, assume that they are static­sensitive 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 device
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.

Service manual Safety 7

General warnings

Warnings indicate conditions or practices that could lead to illness, injury, or death.

Warnings related to the environment

WARNING The power cord is considered the disconnect device for
isolating this equipment from supply mains. Do not position the equipment
so that it is difficult to reach or disconnect.

WARNING To avoid a possible explosion, do not use the
electrocardiograph in the presence of flammable anesthetics: mixtures
containing air, oxygen, or nitrous oxide.

WARNING When transporting the electrocardiograph on a cart, tuck the
patient cable away to keep them clear of the wheels and to minimize trip
hazards.

Warnings related to accessories and other equipment

WARNING To avoid the risk of electric shock, this equipment must only
be connected to a supply mains with protective earth.

WARNING For operator and patient safety, peripheral equipment and
accessories that can come in direct patient contact must be in compliance
with all appropriate safety, EMC, and regulatory requirements.

WARNING All signal input and output (I/O) connectors are intended for
connection of only devices complying with IEC 60601-1, or other IEC
standards (for example, IEC 60950), as appropriate to the device.
Connecting additional devices to the electrocardiograph might increase
chassis or patient leakage currents.

WARNING The electrocardiograph has not been designed for use with
high-frequency (HF) surgical equipment and does not protect against
hazards to the patient.

WARNING Defective batteries can damage the electrocardiograph.
Visually inspect the battery at least monthly, if the battery shows any signs
of damage or cracking, it must be replaced immediately and only with a
battery approved by Welch Allyn.

WARNING Improper disposal of batteries may create an explosion or
contamination hazard. Never dispose of batteries in refuse containers.
Always recycle batteries according to local regulations.

WARNING All signal input and output (SIP/SOP) connectors should not be
contacted by patient directly and indirectly through the user during
operation.

WARNING Use only parts and accessories, including thermal paper, that
were supplied with the device and available through Welch Allyn. The use
of accessories other than those specified may result in degraded
performance or unsafe use of this device.

8 Safety CP 150 12-lead resting electrocardiograph

Warnings related to using the electrocardiograph

WARNING No modification of this equipment is allowed.

WARNING This device captures and presents data reflecting a patient’s

physiological condition. When reviewed by a trained physician or clinician,
this data can be useful in determining a diagnosis. However, the data
should not be used as a sole means for determining a patient’s diagnosis or
prescribing treatment.

WARNING To provide CF protection use only accessories approved by
Welch Allyn. Visit www.welchallyn.com. The use of any other accessories
can result in inaccurate patient data, can damage the equipment, and can
void your product warranty.

WARNING To avoid serious injury or death, take these precautions during
patient defibrillation:

• Avoid contact with the electrocardiograph, patient cable, and patient.

• Verify that the patient leads are properly connected.

• Place defibrillator paddles properly in relation to electrodes.

• After defibrillation, pull each patient lead out of the patient cable and inspect
the tips for charring (black carbon marks). If there is any charring, the patient
cable and individual leads must be replaced. If there is no charring, fully
reinsert the leads into the patient cable. (Charring can occur only if a lead is
not fully inserted into the patient cable before defibrillation.)

WARNING To prevent the spread of infection, take these precautions:

• Dispose of single-use components (for example, electrodes) after using
them once.

• Regularly clean all components that come in contact with patients.

• Avoid ECG testing for patients with open, infectious sores.

WARNING Avoid positioning any leads or cables so that they could easily
trip someone or become wrapped around a patient’s neck.

WARNING To ensure safe use of the device, follow the documented
maintenance procedures.

WARNING Only qualified service personnel should attempt to repair the
electrocardiograph. In case of a malfunction, call Technical Support.

WARNING Do not perform ST segment analysis on the ECG screen
display, since these ECG representations are scaled. Make manual
measurements of ECG intervals and magnitudes on printed ECG reports
only.

WARNING To maintain diagnostic accuracy and to comply with IEC
60601-02-51 and IEC 60601-02-25, do not scale (re size) when sending a
saved ECG to an external printer.

WARNING To avoid injury, do not touch the print head immediately after
printing. It might be hot.

Service manual Safety 9

WARNING To avoid the risk of associating reports with the wrong
patients, make sure that each test identifies the patient. Do not save a test
to the patient record without patient identification associated with the
report.

General cautions

Cautions indicate conditions or practices that could damage the equipment or other
property.

CAUTION Federal US law restricts sale of the device identified in this
manual to, or on the order of, a licensed physician.

CAUTION When removing the electrocardiograph from storage, allow it to
thermally stabilize to surrounding environmental conditions before using it.

CAUTION To prevent possible damage, do not use sharp or hard objects
to press the touch screen or the buttons. Only use fingertips.

CAUTION Do not expose the patient cable to strong ultraviolet radiation.

CAUTION Do not pull or stretch the patient cable. Doing so could result in

mechanical or electrical failures. Form the patient cable into a loose loop
before storing.

CAUTION Avoid positioning the patient cable where it might get pinched,
stretched, or stepped on. Otherwise, measurements might no longer be
accurate, and repair might be necessary.

CAUTION Using the equipotential terminal for anything but grounding
purposes may contribute to damage of the device.

CAUTION Portable and mobile RF communications equipment can affect
the performance of the electrocardiograph.

CAUTION The electrocardiograph meets the Class A requirements of IEC
60601-1-2 regarding incidental emission of radio frequency interference. As
such it is suitable for use in commercial grade electrical environments. If
the electrocardiograph is used in residential grade electrical environments
and you experience incidental interference with other equipment that uses
radio frequency signals to operate, minimize the interference.

CAUTION Other medical equipment—including but not limited to
defibrillators, ultrasound machines, pacemakers, and other stimulators—
may be used simultaneously with the electrocardiograph. However, such
devices may disturb the electrocardiograph signal.

CAUTION The power cord must be disconnected from AC power before
cleaning, maintaining, transporting, or servicing.

10 Safety CP 150 12-lead resting electrocardiograph

CAUTION The requirements of AAMI EC11, Section 3.2.7.2, Frequency
and Impulse Response, for an impulse triangle waveform may be impacted
by up to 5 milliseconds of small amplitude dampened ringing immediately
after the impulse when the muscle filter (35 Hz) is turned on or a small
amplitude offset when the baseline filter (0.5 Hz) is turned on. These filters,
in any combination turned on or off, meet the AAMI requirements.
Measurements performed by the optional interpretation algorithm are
unaffected by any filter selections.

Note The entire patient cable, up to and including the electrodes are considered

to be an Applied Part.

Electrical safety testing

Welch Allyn recommends performing ground continuity and leakage current tests after
all open-case repairs and dielectric strength testing 1 when replacing the power supply or
primary wiring according to EN/IEC 62353 - Medical Electrical Equipment - Recurrent
Test and Test After Repair of Medical Electrical Equipment.

Due to the variability of test equipment in the field, Welch Allyn does not include specific
instructions to perform electrical safety tests. When performing electrical safety tests,
refer to your test equipment manuals for detailed instruction. The following table
provides connections and test limits to assist you in performing these tests.

Test Limits

Ground continuity Ground continuity from EP stud* (equipotential terminal) to the Gnd pin of the

IEC power connector shall be no greater than 0.1 ohms.

Leakage current Leakage current shall be less than 500 µA from EP stud* to mains (Line and

Neutral pins of the IEC power connector).

Insulation resistance Insulation resistance measurements shall be performed with 500V DC from EP

stud to mains (Line and Neutral pins of the IEC power connector).

* To locate the equipotential terminal, see “Controls, indicators, and connectors.”

1

Perform this test only if there is a reason to doubt the integrity of the electrical insulation (e.g. multiple
trips of a residual-current device or liquid ingress of a saline solution). If you determine this test should
be performed, return the device to Welch Allyn for service.
