bystanders, or damage to the device. Contact Welch Allyn service for additional training options.
4. To maintain designed operator and patient safety, peripheral equipment and accessories used that can come in
direct patient contact must be in compliance with UL 60601-1, IEC 60601-1, and IEC 60601-2-25. Only use
parts and accessories supplied with the device and available through Welch Allyn, Inc.
5. Patient cables intended for use with the device include series resistance (9 Kohm minimum) in each lead for
defibrillation protection. Patient cables should be checked for cracks or breakage prior to use.
6. Conductive parts of the patient cable, electrodes, and associated connections of type CF applied parts, including
the neutral conductor of the patient cable and electrodes, should not come into contact with other conductive
parts including earth ground.
7. Do not attempt to clean the patient cables by submersing into a liquid, autoclaving, or steam cleaning as this
may damage equipment or reduce its usable life. Wipe the exterior surfaces with a warm water and mild
detergent solution and then dry with a clean cloth. Use of unspecified cleaning/disinfecting agents, failure to
follow recommended procedures, or contact with unspecified materials could result in increased risk of harm to
users, patients and bystanders, or damage to the device.
8. The device is part of an integral personal computer-based diagnostic system. The user must adhere to all
warnings in order to ensure safe and reliable performance.
9. If operated on AC (~) power, the personal computer must be connected with its original power cable to an
electrical installation that complies with applicable regulations for environments where patients are treated.
10. The personal computer used and any peripheral devices connected to it must be approved to the appropriate
safety standard for nonmedical information technology equipment per IEC 60950, or its national variants. The
personal computer and any peripheral devices connected to it, being non-medical electrical equipment, must be
USER SAFETY INFORMATION
Page | 8
situated outside the patient environment per IEC 60601-1–1. To ensure the safety of the patient it must not be
possible for the operator to touch the patient and the computer at the same time. In general, at least 1.5 meters
(5’) of open area must surround the patient to achieve this.
11. If the personal computer is situated within the patient environment, ensure that its level of safety is that of
medical electrical equipment per IEC 60601-1. This may be accomplished by powering the computer and any
other equipment connected to it through an isolation transformer or by operating on battery power.
12. If the personal computer is situated within the patient environment, to maintain designed operator and patient
safety when a LAN network connection is being used, the network cable must be connected to the device
through an Ethernet isolator module that complies with IEC 60601-1-1 (available from Welch Allyn).
13. ECG electrodes could cause skin irritation; patients should be examined for signs of irritation or inflammation.
Electrode materials and ingredients are specified on the packaging or are available from the vendor upon
request.
14. To avoid the possibility of serious injury or death during patient defibrillation, do not come into contact with
device or patient cables. Additionally, proper placement of defibrillator paddles in relation to the electrodes is
required to minimize harm to the patient.
15. Proper clinical procedure must be employed to prep the electrode sites and to monitor the patient for excessive
skin irritation, inflammation, or other adverse reactions. Electrodes are intended for short-term use and should
be removed from the patient promptly following testing. Do not mix electrodes made of dissimilar metals.
16. To avoid potential for spread of disease or infection, single-use disposable components (e.g., electrodes) must
not be reused. To maintain safety and effectiveness, electrodes must not be used beyond their expiration date.
17. A possible explosion hazard exists. Do not use the device in the presence of flammable anesthetic mixture.
18. Possible malfunction risks may be present when installing third-party software. Welch Allyn, Inc. cannot verify
the compatibility of all possible hardware/software combinations.
19. The device has not been designed for use with high-frequency (HF) surgical equipment and does not provide a
protective means against hazards to the patient.
20. When the 40 Hz filter is used, the frequency response requirement for diagnostic ECG equipment cannot be
met. The 40 Hz filter significantly reduces high-frequency components of the ECG and pacemaker spike
amplitudes, and is recommended only if high-frequency noise cannot be reduced by proper procedures.
21. The quality of the signal produced by the device may be adversely affected by the use of other medical
equipment, including but not limited to defibrillation and ultrasound machines.
22. Use only recommended alkaline battery cells with WAM™. Use of other cells may present a risk of fire or

27. When necessary, dispose of the device, its components and accessories (e.g., batteries, cables, electrodes),
and/or packing materials in accordance with local regulations.
28. Proper functioning backup items such as a spare patient cable, display monitor, and other equipment are
recommended on hand to prevent delayed treatment due to an inoperable device.
Caution
1. Do not pull or stretch patient cables as this could result in mechanical and/or electrical failures. Patient cables
should be stored after forming them into a loose loop.
2. Proper functioning backup items such as a spare patient cable, front-end device, display monitor, and other
equipment are recommended on hand to prevent delayed treatment due to an inoperable device.
3. Windows compatibility, updates and anti-virus policy: The RScribe™ software has been fully tested with
Windows 7 Professional Service Pack 1, Windows 8.1 Professional, and Windows 10 Pro operating systems.
The RScribe software has also been tested with Windows Server 2008 R2 Service Pack 1 and Windows Server
2012 R2. Although it is unlikely that Windows updates and security patches affect RScribe functionality,
Welch Allyn recommends turning automatic Windows update off, and periodically running it manually. A
functional test should be executed after update, which includes acquiring a recording, editing measurements and
printing a report, as well as importing an order and exporting results, if activated. Compatibility of RScribe
with corporate anti-virus software packages has been evaluated. Welch Allyn recommends excluding the
RScribe database folder (Normally C:\ProgramData\MiPgSqlData on a stand-alone system or the server) from
the folders to be scanned. In addition, anti-virus patch updates and system scans should be scheduled for time
periods when the system is not actively in use or performed manually.
4. No other non-recommended PC application software should be running while the RScribe application is being
used.
5. It is recommended that all resting ECG workstations and review stations be periodically updated with Microsoft
critical and security updates to protect from malware attacks and to fix critical Microsoft software issues.
6. To prevent delivery of malware into the system Welch Allyn recommends that institution operating procedures
are written to prevent malware to be transmitted into the system from removable media.
7. The WAM will only work with receiving devices that are equipped with the appropriate option.
8. This WAM is not recommended for use in the presence of imaging equipment such as Magnetic Resonance
Imaging (MRI) and Computed Tomography (CT) devices, etc.
9. The following equipment may cause interference with the WAM RF channel: microwave ovens, diathermy units
with LANs (spread spectrum), amateur radios, and government radar.
10. AA batteries are known to leak their contents when stored in unused equipment. Remove battery from WAM
when not used for an extended period of time.
USER SAFETY INFORMATION

11. Be careful to insert the correct lead wire into the connector block with the appropriate input connector by matching
the lead wire labels to the WAM or AM12 lead labels.
Notes
1. Local Administrator permissions are required for software installation, application configuration, and software
activation. Local User privileges are required for application users. Roaming and temporary accounts are not
supported.
2. 8-hour timeout expiration is automatically controlled by the system. Each operation that occurs (e.g. Exam
Search, Patient Search, editing exams, starting an exam, etc.) will reset the timeout start time. When there is no
interaction with the system for the timeout duration, the user is prompted to enter login information.
3. When the server is unavailable in a distributed configuration, the client workstation will notify the user with a
prompt to proceed in Offline Mode or cancel. Scheduled orders are not available. An exam can be conducted
with manually entered demographics and will be stored locally. When the server comes available, the user is
prompted with a list of unsent exams and a selection to send exams to the modality manager database.
4. Patient movements may generate excessive noise that may affect the quality of the ECG traces and the proper
analysis performed by the device.
5. Proper patient preparation is important to proper application of ECG electrodes and operation of the device.
6. There is no known safety hazard if other equipment, such as pacemakers or other stimulators, is used
simultaneously with the device; however, disturbance to the signal may occur.
7. If an electrode is not properly connected to the patient, or one or more of the patient cable lead wires is damaged,
the display will indicate a lead fault for the lead(s) where the condition is present.
8. A thick baseline presentation on the display while using the AM12 may be due to a calibration error. Review the
LED indicator on the AM12 to ensure the unit is connected, or disconnect and reconnect to the PC USB port to
re-calibrate.
9. The WAM will automatically start flashing LEDs if the batteries have been discharged below 1.0 volts.
10. During normal WAM/AM12 operation, the green LED will display continuously.
11. If the WAM battery cover is opened during transmission, the device will stop transmitting. The battery must be
reinserted and the cover must be applied to resume operation.
12. The WAM will automatically turn off (LEDs off) if the battery has been severely discharged.
13. The WAM will automatically turn off when the electrocardiograph is powered down.
14. The WAM will automatically turn off after being disconnected from the patient. This will happen regardless of
RScribe battery/AC power state.
15. A thick baseline presentation on the display while using the WAM may be due to the WAM being turned off,
having no battery, not being paired correctly, operating out of range, or due to a calibration error. Review the
LED indicator and auditory advisory on the WAM to ensure the unit is turned on, has proper battery level, is
paired correctly, and is within recommended proximity of the electrocardiograph, or power cycle the WAM to
re-calibrate.

devices (IEC 60601-1-2). This IEC standard has been adopted in Europe as the European Norm (EN 60601-1-2).
The device should not be used adjacent to, or stacked on top of other equipment. If the device must be used adjacent
to or stacked on top of other equipment, verify that the device operates in an acceptable manner in the configuration
in which it will be used.
Fixed, portable, and mobile radio frequency communications equipment can affect the performance of medical
equipment. See the appropriate EMC table for recommended separation distances between the radio equipment and
the device.
The use of accessories, transducers, and cables other than those specified by Welch Allyn may result in increased
emissions or decreased immunity of the equipment.

RScribe is a multi-lead, diagnostic, computer-based resting electrocardiograph capable of acquiring, viewing,
transmitting, printing, and storing ECG data.
RScribe models ordered with the VERITAS™ resting ECG interpretation algorithm option are capable of specific
age and gender interpretation criteria. The VERITAS algorithm provides an over-reading physician with a silent
second opinion through diagnostic statements displayed on the ECG report. For additional information on the
VERITAS algorithm, please refer to the Physician’s Guide to VERITAS with Adult and Pediatric Resting ECG
Interpretation (see Accessories).
RScribe can be configured with bidirectional connectivity and DICOM® protocol support.
The RScribe application is integrated with a patient and exam management system that handles the scheduling of
exams, database storage and maintenance, exam and patient search, printing, communication with external systems
and dispatches the modality dependent acquisition and review functions. RScribe can be configured for data
distribution. When so configured, the database resides on a server supporting a number of networked client
workstations.
The RScribe Review software offers authorized users with the ability to schedule new exams when not linked to an
external scheduling system, view reports, enter conclusions, and generate printed or electronic reports for completed
exams.
The RScribe server, workstations, and review stations can be set up as Citrix® Application Servers for remote access
from client computers with Citrix XenApp™ installed.
The RScribe supports print formats that include:
Standard or Cabrera,
3+1,
