Safety Summary

CP 100 and CP 200 Electrocardiograph

Servicing 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 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.

WARNING Do not use the CP 100 and CP 200 Electrocardiograph in an MRI suite or hyperbaric chamber.

WARNING Do not autoclave the CP 100 and CP 200 Electrocardiograph or patient cable.

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 79

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 IEC 60601-1-1. Measure the leakage currents to confirm that no electric shock hazard exists.

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

Directions for Use

Safety Summary

Warnings Related to Using the Electrocardiograph

WARNING Avoid positioning any leads or cables so that they could easily trip someone.

WARNING Satisfactory maintenance procedures must be implemented, or equipment failure and health hazards may result.

Warnings Related to Repairing the Electrocardiograph

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.

WARNING While under warranty, the electrocardiograph must be serviced only by a Welch Allyn service technician.

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

WARNING Consider all electrical and electronic components of the monitor as static-sensitive.

Electrostatic Discharge (ESD)

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.

6

Safety Summary

CP 100 and CP 200 Electrocardiograph

•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.

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 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.
