Battery Deep-Discharge Disconnect Added
A battery deep-discharge disconnect has been added to reduce the likelihood that your
CP 100 or CP 200 electrocardiograph will operate on a deeply discharged battery. The
disconnect prevents permanent damage to the battery when the battery is left uncharged
for long periods of time.
This functions automatically when the electrocardiograph battery voltage is less than
5.25V in sleep mode. Once a battery disconnect has occurred, the electrocardiograph will
not operate on battery power until it is charged to 6.2V or higher. This also protects the
electrocardiograph from operating on a malfunctioning battery that cannot be charged to
6.2V or higher.
Reset Button
If the electrocardiograph stops functioning, you can press and hold the Power On/Off key
for approximately 7 seconds to restart the electrocardiograph. Release the key once the
restart begins. The key is located on the upper left of the electrocardiograph keyboard.

Alternate Patient Cable and Leads
The Lead configuration has changed so that all individually replaceable lead wires extend
from the same end of the patient cable. This new configuration is intended to make the
connection of the lead wires easier for you. It is different now then it has been in previous
models where the LL (F) and RL (N) leads attached to the opposite end of the patient
cable with respect to the other leads. See Figure 3“Patient Cable and Leads”.

Updated Information for the CP 100/CP 200
Heart rate monitor operation
The heart rate indicated on the CP 100 or CP 200 LCD display is for reference only. Make
manual measurements of the ECG intervals and magnitudes on printed ECG reports only.
The increased R wave amplitudes that are produced by some patient simulators may
produce heart rate readings two times higher than normal because the R waves can be
counted as T waves.
The CP 100 and CP 200 devices are not intended to be used as heart rate monitors. Heart
rate monitors are covered by other standards for example: ANSI/AAMI standard EC13:
Cardiac monitors, heart rate meters and alarms.
Artifact
A combination of abnormally large R wave amplitude and waveform shapes delivered by
some patient simulators can trigger artifact warnings. These warnings are not consistent
with actual patient morphologies. The noise warning is designed as a guide to limit low
quality ECGs.
The CP 100 and CP 200 devices are compliant to all applicable standards specified in the
device manual for diagnostic electrocardiographs including: IEC/EN 60601-2-51 and ANSI/
AAMI EC11.
Reducing Artifact
• Use only resting tab electrodes that have not past their product expiration date.
Store only in an air tight pouch within the product recommended environmental
conditions.
• When using the reusable bulbs, limb plates, or clamp electrodes, always replace
expired or dried up electrode gel.
• When using the reusable bulbs, limb plates, or clamp electrodes, use only an
ECG conductive gel to obtain optimum conductivity. Do not use ultrasound gel.
• Orient the adapter (alligator) clips so that the metal from the clip is able to make
contact with the conductive area of the resting tab electrode.
4 Welch Allyn CP Series Electrocardiographs
• Replace the patient lead if the banana spring at the end of the lead is broken or
damaged.
Updated Battery Information for the CP 100/CP 200
Electrocardiograph Battery - Preparation and Operation
Battery performance:
The sealed lead-acid battery provides 200 to 300 discharge/charge cycles under normal
operating conditions before it should be replaced. Typical battery usage will require
battery replacement approximately once per year. Reduced battery performance and
longevity will result if the recommendations for maximum battery performance are not
followed.
The electrocardiograph uses a single, rechargeable Sealed Lead Acid (SLA) battery pack. It
is designed to print up to 100 continuous rhythm ECG pages or to print 25 AUTO ECG
tests per full charge. The typical charge time of the sealed lead-acid battery is 12-16 hours,
but can take up to 36 hours for a highly discharged battery.
Prior to using your new electrocardiograph in battery mode:
Caution Charge the Battery. Upon receipt of your new electrocardiograph, it is
important to charge the electrocardiograph's battery for at least 12 hours before
using it in battery mode.
Note
The electrocardiograph is fully functional when connected to AC power,
regardless of the battery charge state. Using the electrocardiograph while
charging the battery does not affect the charge time.
New Features for this Release 5
For maximum battery performance and longevity:
• Charge the battery whenever possible by connecting the electrocardiograph to AC
power after each use.
The CP 100/CP 200 provides a trickle charge to keep the battery fully charged.
Continuous charging will maximize the battery performance and longevity and will
not overcharge or degrade the battery.
• Fully recharge the battery immediately after it becomes fully discharged. A fully
discharged battery without an immediate recharge may require an extended charge
time (up to 36 hours) and permanently degrade battery performance and longevity.
• Use only the CP 100/CP 200 electrocardiograph's integral charger to recharge the
battery.
• Use only a Welch Allyn CP 100/CP 200 approved replacement battery (REF 100660).
• Avoid using or storing your electrocardiograph in hot locations or in direct sunlight.
To check the battery charge status:
To fully charge the battery, leave the electrocardiograph plugged into AC power until you
see the fully charged indication on the display. A battery status symbol appears in the top
portion of the electrocardiograph display:
Note
Battery is charging
Electrocardiograph
Display
Battery fully charged (symbol will
appear solid white on the
electrocardiograph display)
Replace your battery if you are unable to perform your expected number of ECGs
per day after a full charge cycle. (12 hour minimum, up to 36 hours if deeplydischarged).

Update Through Software Version 2.5
This update describes changes in operation through software version 2.5 of the CP 100
and CP 200 electrocardiographs and the CP 200 spirometry option. This document
supplements information in the following manuals:
• CP 100 12-Lead Resting Electrocardiograph Directions for Use (mat. 708794)
• CP 200 12-Lead Resting Electrocardiograph Directions for Use (mat. 708793)
• CP 200 Spirometry Option Directions for Use (mat. 708795)
Lead Quality Feedback
CP 100, CP 200
Lead quality messages, which appear on various screens, now include both lead-off and
artifact information.
For good quality recordings, leads must be connected and artifact free. If you print an
Auto ECG despite lead-off or artifact conditions (by overriding the “Waiting for 10 seconds
of quality data” message), the report reflects those conditions. In the case of lead-off
signals, the report shows square waves. In the case of artifact, the report might include a
warning to use the interpretation (if any) with caution.
To eliminate artifact, you might need to re-prep the patient, use fresh electrodes, or
minimize patient motion during the recording.
For additional feedback on lead quality, you can now enable an artifact report. This report,
a 12x1 format with all filters disabled, shows the leads with artifact so that you can
remedy the problem. (The normal Auto ECG report with filters enabled might mask some
of the artifact issues.) When enabled, the artifact report prints automatically with the Auto
ECG report whenever artifact is detected and you override the “Waiting for 10 seconds of
quality data” message.
To enable the artifact report, press the Menu key . Choose ECG Settings >
Auto Report Settings > Artifact Report > On.
Heart Rate
CP 100, CP 200
A four-beat average heart rate (HR) now appears in real time on the screen.
Body Mass Index
CP 100, CP 200
The patient’s body mass index (BMI) now appears on the Enter New Patient screen and
on ECG and spirometry reports when height and weight are entered.

The Welch Allyn electrocardiograph and spirometry products (subject devices) are
intended for use by trained operators in health facilities. The subject devices provide the
following diagnostic functions:
• Acquiring, viewing (CP 200), storing (CP 200), and printing ECG waveforms using ECG
front end modules (patient cables) and associated accessories that provide signal
acquisition for up to twelve (12) leads of patient ECG waveforms through surface
electrodes adhered to the body.
• Using optional algorithms to generate measurements, data presentations, graphical
presentations and interpretative statements on an advisory basis. These are
presented for review and interpretation by the clinician based upon knowledge of the
patient, the result of physical examination, the ECG tracings and other clinical
findings.
• Using the optional CP 200 spirometry module and associated accessories to acquire,
view, store and print measures and waveforms of pulmonary function including, but
not limited to, maximal volume and flow of air that can be moved in and out of the
patient's lungs. These measures are used in the diagnosis and monitoring of lung
diseases and interventions for the treatment of certain lung diseases. The spirometer
should only be used with patients able to understand the instructions for performing
the test.
“Indications for use” statement expanded
CP 100, CP 200
The electrocardiograph is one of the tools that clinicians use to evaluate, diagnose, and
monitor patient cardiac function.
The 12-lead ECG interpretive algorithm provides a computer-generated analysis of
potential patient cardiac abnormalities which must be confirmed by a physician with other
relevant clinical information.
The optional CP 200 spirometry module is indicated for use in clinical situations to assess
a patient's pulmonary health status and evaluate symptoms, signs, or abnormal laboratory
test results.
Spirometry is indicated for use in various common clinical situations:
• Assessing health status before a patient begins strenuous physical activity.
• Evaluating the following symptoms, signs, or abnormal laboratory tests:
Symptoms — dyspnea, wheezing, orthopnea, cough, phlegm production, chest pain
Signs — diminished breath sounds, overinflation, expiratory slowing, cyanosis, chest
deformity, unexplained crackles, shortness of breath
Abnormal laboratory tests — hypoxemia, hypercapnia, polycythemia, abnormal chest
radiographs

Recording an Auto ECG
WARNING To avoid the risk of associating ECG reports with the wrong patients,
each report must identify the patient. If any ECG report does not identify the
patient, write the patient identification patient information on the report
immediately following the ECG test.
An Auto ECG is a report typically showing a 10-second acquisition of 12 leads of ECG
information combined with patient data, interpretation, and measurements matrix. Two
user-defined formats are available: Auto Report 1 or Auto Report 2. To learn how to set up
the Auto ECG report format, see “About Auto ECG Reports” in the Directions for Use.
As shown in the following diagram, there are the two types of Auto ECG: normal and stat.
For details, see these procedures:
• “Recording a Normal Auto ECG” on page 49
