Microsoft Windows compatibility, updates and anti-virus policy: The Q-Stress software has been fully tested with Windows 7 Professional Service Pack 1 and Windows 10 Professional. The Modality Manager 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 Q-Stress functionality, Welch Allyn recommends turning automatic Windows update off, and periodically running it manually. A functional test should be executed after update, which includes conducting an exam, as well as importing an order and exporting results, if activated. Compatibility of Q-Stress with major corporate anti-virus software packages has been verified. Welch Allyn recommends excluding the Q-Stress database folder (normally C:ProgramDataMiPgSqlData 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 Q-Stress application is being used.
5.
It is recommended that all cardiac stress 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.
Exams that are saved to the local or server database on the hard drive will cause the device to fill over a period of time. These exams must be removed from the database by deleting or archiving prior to causing the device to cease to operate. Periodic checks of the device’s capacity are recommended; a safe minimum capacity is 3 GB. See Exam Search for ways to select exams for deletion or archiving.
8.
The Q-Stress application will display a warning prompting the user to delete exams when the database reaches a threshold at 3.2 GB of available space. Each stress exam is approximately 40 MB in size and only 30 more exams can be started. When the available storage is at 2 GB, no new stress exams can be started.
9.
To avoid risk of unintentionally booting into a USB device, ensure that the Boot Order in BIOS is set with the SATA hard drive listed first in the boot order. Refer to computer manufacturer’s instruction for entering BIOS on startup and configuring Boot Order.
10. The WAM will only work with receiving devices that are equipped with the appropriate option. 11. 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.
13
USER SAFETY INFORMATION
12. The following equipment may cause interference with the WAM RF channel: microwave ovens, diathermy units with LANs (spread spectrum), amateur radios, and government radar. 13. When necessary, dispose of the device, its components and accessories (e.g., batteries, cables, electrodes), and/or packing materials in accordance with local regulations. 14. 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. 15.

Note(s) 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.
Once the Pre-Exercise phase is started, full disclosure data storage begins and will continue for up to 120minutes. It is recommended to Abort the exam and Begin again if waiting in this phase for up to 60-minutes. This prevents unnecessary data storage, however previously stored full disclosure, ECG events, and BP values are not saved when the exam is aborted.
5.
Patient movements may generate excessive noise that may affect the quality of the ECG traces and the proper analysis performed by the device.
6.
Proper patient preparation is important to proper application of ECG electrodes and operation of the device.
7.
The Beat Consistency Filter (BCF) that produces averaged 12-lead ECG printout introduces an additional twosecond delay to the real-time ECG data when enabled.
8.
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.
9.
If the treadmill COM port was originally set to a USB port that was not used, a TREADMILL FAIL message will appear when the Trackmaster (No Sensing) selection is made in the Local Settings menu. When the COM port is set to Treadmill COM Port 1 or 2, which are serial ports, there will be no TREADMILL FAIL message.
10. If electrode is not properly connected to the patient, or one or more of the patient cable lead wires is damaged, display will indicate a lead fault for the lead(s) where the condition is present. 11. As defined by IEC 60601-1 the device is classified as follows: - Class I equipment
14
