About the Patient Cable and Leads
The patient cable processes the patient’s ECG data and transmits it to the
electrocardiograph. To make handling convenient, the ten leads are arranged to point
toward the appropriate parts of the body. The cable rake, which slides easily, prevents the
chest leads from tangling.

Using the Electrocardiograph Safely
Before using or servicing the electrocardiograph, you must read and understand the
following safety-related information.
General Warnings
The following warning statements apply to electrocardiograph use in general. Warning
statements that apply specifically to particular procedures, such as connecting the patient
cable or performing an ECG test, appear in the corresponding sections of the manual.
Warning statements indicate conditions or practices that could lead to illness, injury, or
death.
Warnings Related to the Environment
WARNING To ensure patient and device safety, leave 5 feet (1.5 meters) of
open area around the patient.
WARNING To avoid a possible explosion, do not use the electrocardiograph in
the presence of flammable anesthetics.
WARNING When transporting the electrocardiograph on a cart, tuck the patient
cable away from the wheels so that it does not present a hazard.
Warnings Related to Accessories and Other Equipment
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. See “EMC Guidance
and Manufacturer’s Declarations” on page 69.
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 may increase chassis or patient leakage
currents. To maintain operator and patient safety, consider the requirements of

Directions for Use Chapter 1 Introduction 15
Warnings Related to Using the Electrocardiograph
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.
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. See “Connecting the
Patient Cable” on page 20.
• 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 and disinfect all components that come in contact with
patients. See “Cleaning the Equipment” on page 52.
• 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 Satisfactory maintenance procedures must be implemented, or
equipment failure and health hazards may result.
WARNING Only qualified service personnel should attempt to repair the
electrocardiograph. In case of a malfunction, call Technical Support and precisely
describe the problem. For phone numbers, see page ii.

General Cautions
The following caution statements apply to electrocardiograph use in general. Caution
statements that apply specifically to particular procedures, such as connecting the patient
cable or performing an ECG test, appear in the corresponding sections of the manual.
Caution statements indicate conditions or practices that could damage the equipment or
other property.
Caution When removing the electrocardiograph from storage, allow it to
thermally stabilize to surrounding environmental conditions before using it.
Caution To prevent possible damage to the keypad, do not use sharp or hard
objects to press keys. Only use fingertips.
Caution Do not expose the patient cable to strong ultra-violet 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 or
stepped on. If the cable’s impedance is altered, 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 Use only parts and accessories supplied with the device and available
through Welch Allyn. The use of accessories other than those specified may
result in degraded performance of this 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 606011-2:2000 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 as described under
“EMC Guidance and Manufacturer’s Declarations” on page 69.
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.

Inspecting the Electrocardiograph
1. Look for obvious signs of shipping damage. If you find any damage, contact Technical
Support. For phone numbers, see page ii.
2. Verify that you have received all appropriate options and accessories. See “Options”
on page 4 and “Accessories” on page 5.
Connecting the Patient Cable
WARNING Conductive parts of the patient cable, electrodes and associated
connections of Type CF applied parts, including the neutral conductor of the
patient cable and electrode, should not come into contact with other conductive
parts, including earth ground.
WARNING To avoid injury to the patient or damage to the device, never plug
patient leads into any other device or wall outlet.
1. Insert all leads into their proper positions, as labeled on the connectors.
Insert connectors fully so that no part of the metal ring remains exposed.
For example, see Figure 12. (To see the whole patient cable with all leads inserted,
see Figure 11 on page 11.)
WARNING Failure to insert all connectors fully may result in a loss of energy
being delivered to the patient during defibrillation and damage to the patient
cable itself. For other warnings related to defibrillation, see page 15.
2. Plug the patient cable into the port on the front of the electrocardiograph.
See Figure 13.
