This person installs and customizes the software, and is responsible for adding and defining users and studies. Only one administrator is defined upon initial installation, but more than one person may be assigned administrator status. User- A person who operates the WR-TestWorks™ software. Users are assigned to categories “user groups” that determine the amount of responsibility allowed: administrator, physician, analyst, technician, and clerk. At this point, all non-administrators have the same access rights. In future releases, the administrator may assign the access rights for each user level.

A patient can participate in more than one study; however, a visit (and its member tests) belongs to only one study. Studies are useful for grouping related visits and for defining the rules for what tests constitute a visit. In non-trial scenarios, a study is simply an entire database of patients, visits, and tests, often for a given time period. Patient- A patient is a person who undergoes tests within a study by means of one or more visits. Patient attributes include demographic data such as name, date of birth, gender, and so on (data that never changes or changes infrequently). Visit- A visit can consist of one or more tests and has certain information about the patient associated with it (such as height and weight). Typically, all tests within a visit take place on the same day or within a short period of time. Test- A test is a single session of collecting data from a patient. The test has a date associated with it, a technician, a set of raw data, etc. Analysis- An analysis is an interpretation of raw test data. The same set of raw test data can be analyzed in more than one way. Each analysis may have different analysis parameters and/or use different analysis techniques. Report- A report is a presentation of an analysis or group of analyses. Reports are typically previewed in a window before being printed. A single analysis can be represented in more than one report. For example, a full report, a summary report, etc. Functionality:   Test Explorer- Through the Test Explorer, users can view the patients and their associated tests and analyses in a particular study. Many tasks can be started in the Test Explorer, such as patient data editing, beginning a new test, viewing saved tests and analyses, and more. Component- A software module associated with a medical device.

Page | 10 WR Medical Electronics Co • 1700 Gervais Avenue • Maplewood, MN 55109 USA Phone: 800-635-1312 • Fax: 651-604-8499 • Web:www.wrmed.com SETUP ON WINDOWS 7 COMPUTERS Windows 7, due to updated security standards enacted by Microsoft, requires some extra steps for accurate operation. The first requirement is that the user account for login to the computer must be set up as an administrator, via the Windows User settings system. The program must also be set to run as an administrator. This should be done prior to the first run of the software. To set the program to run as an administrator, navigate to the installation directory (By default: C:\Program Files\WR Medical\TestWorks\ or C:\Program Files (x86)\WR Medical\TestWorks\) and right click on the TestWorks.exe file, choosing the “Properties” option. In the dialog that opens up, click on the “Compatibility” tab. At the bottom is a button for changing settings for all users. Click this, and then check the box for “Run this program as administrator”. At this time the software may be run. There will be some warnings about being unable to locate the master database. This is normal. Simply exit the program, and run it again. All errors should have cleared up. RECOVERING FROM A NON-ADMINISTRATOR INSTALLATION In the event a system was run as a non-administrator, it may be possible to correct this. The first step will be to go through ensuring the user(s) accessing WR-TestWorks are administrators in the Windows 7 system, and setting the program to run as administrator. Before running the program again, however, some extra steps must be taken. The most important thing is to re-acquire the data. As part of Windows 7’s protections, the data gets modified separately from the normal location. This location is a subset of the user’s Application Data directory. This can be found at the path “C:\Users\<user login>\AppData\Local\VirtualStore\Program Files (x86)\WR Medical\TestWorks\Data\”. These files should be backed up, along with the data in the normal “Data” directory accessed via the icon on the desktop. Then, the files from the “AppData” directory should be copied and overwritten to the normal installation directory. WARNING: If the computer is part of a domain network with multiple user logins, the above method can cause loss of patient data. In this case, the safest option is to simply copy the data from the “AppData” location for archival purposes, and start with a new blank study to ensure no loss of data or corruption. NOTE: If the data is stored at a network location (Such as S:\Neuro\WR-TestWorks\Data\ or \\shareserver\Neuro\TWData) there is no need to copy the data and may be safely skipped. Upon re-running the program, the user will be prompted to re-enter all settings and license keys. There may also be some errors about locating data. Simply close the program and reopen. The errors should be gone at this stage. In the event the errors have not disappeared, please contact our support staff, who can assist in correcting any problems that may have arisen.
