Setting Up Your System
Installing the Remote Unit Simply connect the remote receiver to the supplied cable and plug the cable into any available USB port on the computer or the keyboard. Extension cables for the receiver are available for long examination rooms. Place the receiver where it is most likely to pick up the signals from the hand controller. Batteries last for approximately 6 months and are available at most drugstores or electronics supply store. Batteries are also available directly from your dealer. In the event you notice the unit is not always responding to button presses, or that you must point the controller directly at the remote receiver, install a fresh pair of batteries in the hand controller.
Installing the Security Key To install the Security Key, simply plug the Key into any available USB port on the computer. Once finished setting up and calibrating the unit, the Keyboard and mouse may be disconnected and stored. If you had installed your Security Key in a USB port on the keyboard, it now must be moved to the spare USB port on the computer.
Starting Up Your Stimuli system from Accommodata Corporation can automatically turn on and off at preset times. This is adjusted through the “Schedule” option under “Energy Saver” of the System Preferences control panel. Please refer to Apple documentation. You may also start up manually at any time by pressing the Power button on the unit. The system will be available for use in about a minute. Stimuli is set to launch when the computer is started. If it is not configured this way, or you have exited Stimuli, you may launch Stimuli by pressing the “Star” button on the hand controller. (If a keyboard and mouse are connected, you may also launch Stimuli by double-clicking its icon on the desktop.) When you see the Stimuli startup screen press the Next Test the tests.

The Stimuli Remote
Designed for ease of use, the lightweight Stimuli Remote allows wireless control of all functions without the need for a bulky wired controller, keyboard or mouse. The buttons are luminescent for use in low light, while the geometric layout allows the practitioner to make selections without looking at the remote. Logical groupings of functions make control of each test intuitive. The column of Direct Access Size buttons are also useful for directly accessing all major test suites as described below. Its range is over 7.6M (30 feet) with a wide dispersion angle. A “Help “ Screen and all Stimuli setup screens are available through the “Menu” button on the bottom center of the wireless remote. The Help option will show which buttons affect each particular test.

Calibrating the System
Your system should be delivered calibrated for your examination room from your local dealer. If for some reason you wish to change the calibration or if you have moved the unit and need to adjust the calibration, follow these instructions: Press the Menu button on the handheld remote control to reach the man Menu screen. Using the Up and Down navigation buttons on the remote, scroll down until Calibration is highlighted and press “Select”. You can navigate the calibration screen with your Right and Left buttons and then use the Up/Down buttons to adjust that aspect. The on-screen calibration calculator tells the user the measurable on-screen size. The maximum resolution setting for the computer must be used. (For older CRT displays that have adjustable rasters, the following procedure requires confirming the size of the test “E” by measuring it on the screen with a ruler.) Page 5
Calibration of the Stimuli System requires three steps. Step #1. Adjust display to its maximum resolution. The maximum resolution setting for the computer must be used.
The computer should arrive already set to its maximum resolution. To confirm this or to adjust the resolution of the screen, launch the System Preferences on top of Stimuli by pressing the Star button.
Choose the “Displays” function in under “Hardware” to set to the maximum resolution. Please refer to the Apple documentation that came with your computer. If the mouse is not connected to the system simply plug it into a USB port and it will begin working. Page 6
ACTION: Adjust the Resolution of the monitor to its maximum by choosing the setting. Close the Preferences window and click on the Stimuli screen. OUTCOME: Your system is now set for the highest resolution.
Step #2. Selecting the Platform. ACTION: Ensure that the correct Platform is selected by pressing the Right Circle button to move the white Highlight Box to the “Platform” pane and select the correct “Platform” or computer you are using. For example, when using a typical iMac-based system choose “iMac_21.5”. The “Other” setting is for any other computer display size such as a larger iMac, or an older platform. If using “Other” the horizontal and vertical resolutions must be entered in the fields provided. Then screen’s resolution may be entered as: dots-per-inch (DPI); pixels-per-millimeter; or simply by entering the screen’s actual width in inches or millimeters. The other terms will be automatically calculated. OUTCOME: The above adjustments have selected the type of computer you are using and provided the screen resolution. Page 7
Step #3. Setting the Refraction Distance Measure the refraction distance from screen to patient’s eyes. Using the Left and Right Navigation buttons on the hand controller, move the Highlight Box to the “Foot” adjustment and select the refraction distance to the nearest foot using the Up and Down Circle buttons. Using the Right Circle button, highlight the “Inches” adjustment and adjust the inches for the refraction distance as measured in the room. (If you prefer to work in meters then navigate to the Configuration screen and select Units: “Metric”). For an LCD flat-panel monitor: Confirm the measurement of the calibration target “E”. Measurement is best effected by closing one eye and looking directly at the edge of the letter while aligning a ruler laid on the screen. The indicated measurement should be within a fraction of a millimeter of the measured size. For a CRT monitor: To calibrate Cathode Ray Tube monitors which are separate from the computer, using the Height and Width size adjustments on the monitor itself (refer to monitor’s User Manual), adjust the size of the calibration target “E” until it exactly equals the calculated size. If the “Displays” Control Panel is in front of the letter and blocking your view, simply use the mouse to move the window by clicking and holding the title bar at the top of the window and dragging the window to a new position. Note: If you happen to click anywhere outside the Control Panel, then the Stimuli Calibration Setup screen will come to the front, occluding the Control Panel. Simply select the “System Preferences” function again. Close the “Displays” Control Panel. Click once on the Calibration Setup screen to ensure it is in the front to receive commands. Now press the Menu button once on the hand controller to get to the Menu screen and using the Down Navigation button select “Quit” and press the Select button. The system will save all settings then quit. Simply relaunch as described in “Starting Up” (above) and the Stimuli system is ready to use. OUTCOME: You have calibrated your system to a fine accuracy. You can easily check the calibration of your system at any time by going to the Calibration window and measuring the actual refraction distance and the size of the calibration target, and checking it against the denoted size and refraction distance.

Setup Media
Stimuli’s fixation/educational videos set the standard. Our exclusive Animal Parade is a pediatric favorite with interesting motorized animals that don’t wear out or require replacement. The automatic sequencing feature moves the system on to a new Animal every few seconds without intervention by the practitioner. Both child and examiner can stay focused on the task at hand with Stimuli™ Animal Parade. A set of cartoons is also included. The Video Play button is used to Play and Pause the selected video clip in the review window. Clips can be directly selected with the “Size” buttons. A number of Video Clip folders are available: The Pediatric Clips folder is included with the system. Sets of Multiple Clips may be added. The Sets of Multiple Clips allow different varieties of video clips to be kept in different sets. This is detailed in “Video Clip Sets” on page 19.

Acuity Charts
The four main varieties of Acuity Chart are: Progressive Lines, Single Line, Single Character, and Multiple Lines of the same size. These are chosen with the Left and Right Navigation buttons. Sizes are varied with both the Up and Down buttons, and the column of Direct Access buttons. Note: additional sizes between those represented by the Direct Access buttons are available, both larger and smaller, with variations in progression (see Setup). In Chart mode, the black Up (some of which are optional).

buttons select the different optotypes available for testing
Option Buttons The two feature buttons and directly above the navigation buttons provide features which act upon the selected chart. These features include a single column when in chart mode, isolation, contour bars, pointer, and an optional inverse (light on dark). Page 12
Pointer A pointer is available when in Line mode. This helps with many younger, older and foreign speaking patients. It is easily controlled by the and buttons along with other test features. The pointer is used to indicate the desired test object in a given line of characters. The pointer automatically sizes to be easily viewable to the patient. Isolation / Contour Bars When operating in the Line or Single Character mode, isolation is available. The two feature buttons directly above the navigation buttons and selectively provide an isolation box along with the other features. When in “single character” mode, contour bars are also available. Random Charts For common letter charts, the first set in a size is a common selection of characters. Each time the Select button is pressed, a new chart of optotypes is presented which eliminates memorization by the patient. The second and third sets of common optotypes are different, but consistent so that the practitioner can eventually memorize them. After the third chart, all charts are randomly generated. This randomly generated selection eliminates the problematic "Memory Effect” of conventional automatic and manual projector systems. Legends Legends are controlled by the star button. Visible legends can be selected in the “Setup” menu. If a remote display panel is used, it will indicate the Chart, Mode, and test details. A second press of the star button provides a second page of legends for multi-line optotype charts. Audible Legends may also be selected which announce the size of the first optotype line, and then announce the identity of each optotype upon a second press of the star button. Young children like this “Talking” test feature which can simplify some testing. Optional Foot Pedals Stimuli was first with foot pedal control of charts. This hands-free innovation is a boon to those working with younger patients or patients with special needs. This option is especially useful if the practitioner wishes to use a number of hand held devices such as an occluder. The optional foot pedal unit allows handsfree control of the chart size Up and Down and Select buttons.
