Replacing the Battery DC Fuse. Replacing the AC Fuses. Storing the Equipment. Discarding the Equipment. Problem-Solving Suggestions. Limited Warranty. Service Policy. A - Specifications. This manual is written for clinical professionals with a working knowledge of medical procedures and terminology as required for monitoring cardiac patients. Before using the CP electrocardiograph for clinical applications—or before setting up, configuring, troubleshooting, or servicing the electrocardiograph—you must read and understand this manual and all other information accompanying the electrocardiograph and related options or accessories.

The Welch Allyn CP electrocardiograph features a full alphanumeric keyboard, an LCD display, full-size user-programmable reports, and the ability to operate on either battery or AC power. The CP electrocardiograph is specifically intended for acquiring and printing ECG signals from adult and pediatric patients. It will be used in clinical settings by trained healthcare providers. The optional interpretation algorithm analyzes these ECG signals to generate measurements and interpretive statements for adults.

The interpretive results are intended only as guidance for qualified physicians and must not be relied upon as diagnoses. The electrocardiograph is one of the tools that clinicians use to evaluate, diagnose, and monitor patient cardiac function. The lead interpretive algorithm provides a computer-generated analysis of potential patient abnormalities which must be used only as guidance for consideration by qualified physicians, together with other relevant clinical information, for purposes of making diagnoses.

The lead interpretive algorithm is not intended for use on pediatric patients. Cards are not included. Use the electrocardiograph almost anywhere. On battery power, you can print up to ECGs continuously before needing to recharge.

Two specially designed carts are available for convenient transport and use of the electrocardiograph, as shown here with the optional cable arm and shelf. To order accessories, call Welch Allyn. For phone numbers, see page ii. This section describes the controls, indicators, and connectors that are part of the electrocardiograph. Begins Auto ECGs, normal and stat. Begins a Rhythm ECG. Stops any current activity. The main menu appears when you press the Menu key.

The cable rake, which slides easily, prevents the chest leads from tangling. The symbols illustrated on the following pages may appear on the electrocardiograph, on the packaging, on the shipping container, or in this manual.

Caution In this manual, indicates conditions or practices that could damage the equipment or other property. Before using or servicing the electrocardiograph, you must read and understand the following safety-related information.

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. 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 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.

Connecting additional devices to the electrocardiograph may increase chassis or patient leakage currents. To maintain operator and patient safety, consider the requirements of IEC Measure the leakage currents to confirm that no electric shock hazard exists.

When reviewed by a trained physician or clinician, this data can be useful in determining a diagnosis. 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. In case of a malfunction, call Technical Support and precisely describe the problem. 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. 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 regarding incidental emission of radio frequency interference.

As such it is suitable for use in commercial grade electrical environments. 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. You can get help with the electrocardiograph in a variety of ways beyond this manual. Look for obvious signs of shipping damage. If you find any damage, contact Technical Support. Verify that you have received all appropriate options and accessories. 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.

Insert all leads into their proper positions, as labeled on the connectors. For example, see Figure To see the whole patient cable with all leads inserted, see Figure 11 on page 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 Plug the patient cable into the port on the front of the electrocardiograph.

See Figure Squeeze the latch. Pull the paper door to the left. If any paper remains in the tray, remove it.

Remove the outer packaging, including the cardboard bottom, from a new pack of paper. Slide the paper into the tray. This is not a sale of the software or any copy of the software; all right, title and ownership of the software remains with Welch Allyn or its vendors.

In case of a malfunction, call Technical Support and precisely describe the problem. For phone numbers, see page ii. Handle static-sensitive components only at static-safe workstation. 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. Always use techniques and equipment designed to protect personnel and equipment from electrostatic discharge. 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.
