Setting Up Your System
Installing the Remote Your system will come with an RF remote which has already been paired with the system. Should the remote need to be reinstalled follow these simple steps: Step 1 Connect the Remote’s USB radio receiver into any available USB port on the computer. When connecting, the receiver’s status light will flash while synchronizing with the system. After this synchronization period, the blinking will stop and the light will remain on. The status light will then blink rapidly while receiving a signal from the remote. Step 2 Ensure that the clear battery protector film that separates the Remote’s battery (located on the back of the remote in the battery compartment) is removed. Step 3 Be sure that the remote’s ON/OFF button (located on the back of the remote) is in the ON position. Pairing If you cannot proceed after these steps, the Remote and the USB Receiver may need to be "paired". Press the ID Pair button (located on the receiver). The status LED will blink once per second. While it is blinking, press the Change ID button (located on the back of the remote). The LED on the receiver will blink rapidly for a few seconds and then return to solid (ON), indicating that pairing is complete.
Installing the Security Key To install the Security Key, simply plug the Key into any available 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 remote control. (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 button on the remote control to advance to the vision testing mode, or use the Direct Access Keyboard to select the desired test. Page 2
The Stimuli Remote
Designed for ease of use, the lightweight Stimuli Remote hand controller allows wireless control of all functions without the need for a bulky controller. The geometric layout allows the practitioner to make selections without looking at the remote. Logical groupings of functions make control of each test intuitive. Its range is over 10M (35 feet) and since it uses Radio Frequency it is not necessary for it to be pointed at the screen and can even be concealed in a pocket. A “Help “ screen and all Stimuli setup screens are available through the “Menu” button on the bottom right of the wireless remote. The Help option will show which buttons control each individual 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 main Menu screen. Using the Up and Down arrow buttons, scroll down until Calibration is highlighted and press Select on the remote or Space/Select on the keyboard. You can navigate the calibration screen controls with the Right and Left arrow buttons and then use the Up/Down arrow buttons to adjust each 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 7
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 or "Z" on the keyboard.
Choose the “Displays” function in under “Hardware” to set to the maximum resolution. Please refer to the Apple documentation that came with your computer. Ensure the mouse is connected to the system. Page 8
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 arrow 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 9
Step #3. Setting the Refraction Distance Measure the refraction distance from screen to patient’s eyes. Using the Left and Right arrow buttons, move the Highlight Box to the “Foot” adjustment and select the refraction distance to the nearest foot using the Up and Down arrow buttons. Using the Right arrow 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 an older CRT monitor: To calibrate Cathode Ray Tube monitors, use 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 remote or Return/Menu on the keyboard to get to the Menu screen and using the Down arrow button select “Quit” and press the Select button on the remote or Space/Select on the keyboard. 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.

Configuring The System Your Stimuli Advanced Duo can be adjusted to suit a great number of individual preferences. Highlight a particular feature with the Right or Left arrow buttons then use Up and Down arrow buttons to select the desired option. The system allows changing numerous features.
Calibration units English or Metric units for refraction computer. Optotype Units Snellen, logMAR or Decimal units for optotype legends. Progression American modified Snellen or true logarithmic chart progression. Red/Green Extinction Allows matching colors to Red/Green glasses. View Direct viewing or Reflected (mirrored) examination lane. Feedback Clicks when tests change with volume control buttons, or Silent operation. Legends Allows selection of Far, Near, Desktop Readout or Audible. Max. Characters/Line Adjust the maximum number of characters on a line. Max. Lines/Chart Allows setting the maximum number of lines on multi-line charts. Progressive Equal number of optotypes per line, or Filled lines on progressive charts. Master Volume Overall volume control. In general, the Menu button (Retuen/Menu on the keyboard) steps back up a level each time it is pressed, all the way back to the current test chart. Page 11
Setup Optotypes Many optotypes are available. Some are options, others are included and may be turned on or off at the clinician’s preference.
Highlight an optotype using the Up
and Down
Activate or deactivate optotypes with the Select
arrow buttons. button (Space/Select on the keyboard).
The system is configured to allow customizing of all optotype sets. The Right
arrow button moves to a customization screen for each hi-lighted optotype.
Choices include: “All optotypes ”, “Standard Selection”, or three “Custom” sets. To make a custom set, use the "volume" Up and Down buttons to select “Custom 1, 2 or 3” Use the Left and Right Navigation buttons to make the cursor square traverse the full list of Optotypes, and the button to select the optotypes desired.

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 (or "V" on the keyboard) is used to Play and Pause the selected video clip in the review window. Clips can be directly selected with the “Size” keys. 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. Page 13
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 arrow buttons. Sizes are varied with both the Up and Down buttons, and with the number row keys of the Direct Access keyboard. Note: additional sizes beyond those represented by the Direct Access keys are available, with variations in progression. If the Modified Progression is configured in Setup, then Up and Down arrows and the Direct Access keys are equivalent (shown with their Snellen "20:" equivalents).
If the Logarithmic Progression is configured, the Up and Down buttons step through the standard logarithmic progression, while the Direct Access keys continue to provide the finer steps of the Modified Progression. For these the Plus and Minus keys also serve to step through the Modified Progression. This gives the practitioner more choices. Page 14
In Chart mode, the "volume" Up and Down remote buttons (or shift-Up and shift-Down arrow keys on the keyboard) select the different optotypes available for testing (some of which are optional). Option Buttons The two feature buttons and (or "comma" and "period" keys) 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). Pointer A pointer is available when in Line mode. This helps with many younger, older and foreign language speaking patients. It is easily controlled by the and buttons (or "comma" and "period" keys) 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 (or "comma" and "period" keys) 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 or Space/Select key 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 or "Z" key. 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 or "Z" key 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 or "Z" key. 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.

Programmability
The initial test screen presented to the patient is a progressive letter chart from 20/20 up to and including 20/80 (depending on screen size). However, Stimuli also supports a programmable chart starting point. To program your favorite chart, size, optotype, and presentation option into memory: 1. Navigate to your favorite test chart, such as the Pediatric single line with Pointer at 20:100. 2. Press the Pause mode (black).
button on the remote or the Pause/"Q" key. The test screen will go into “Sleep”
3. Press the bottom left button, Star button twice or the Legends/"Z" key. You will hear a Ding/ Dong, your test is now programmed. To return to the programmed favorite chart, from anywhere go into Pause and then press the "Square" remote button or the "backquote" key at the top left of the Direct Access keyboard. Stimuli will return directly to your programmed choice. This feature greatly speeds vision testing and helps keep the patient’s attention. The programmed test can be changed at any time. Page 17
Fixation Dot
Upon entering this test, you will be presented a white dot on a black background. Stimuli includes many features to make this the most flexible and useful fixation device. The different features supported include:
1. Disappearing Dot Game. 2. Reversed Black Dot on White background. 3. Animated dot. 4. Flashing Dot. 5. Combinations.
Pressing the Select button or Space/Select key makes the dot disappear and reappear. The and feature buttons (or "comma" and "period" keys) Blink and Animate the dot respectively. For convenience, the Left and Right buttons duplicate the feature buttons. The animated dot moves in a varying trajectory in the patient’s central field. The Up
and Down
buttons turn the background white or black respectively. Page 18
Sizable 4-Dot Test
Our unique sizable Four Dot chart sets the standard. The test is correctly calibrated for the refraction distance. The intensity of of the circles may be adjusted for different Red / Green eyewear to assure maximum extinction (via the Four Dot Setup). This test can be sized with the Up
and Down
buttons.
The external and internal angles in degrees can be displayed or spoken via the
