A. Target White level luminance value: Adjust this setting to your desired luminance level. This is for all Image Systems displays connected to the computer. In most cases the best target for individual displays will already be set on the displays Unit tab automatically.

Typical luminance targets: Grayscale Display = 450-500 cd/m2 Std. Color Display = 175 – 250 cd/m2 High Bright Color = 400 - 450 cd/m2

When different target white levels are set on the unit tabs the “general tab” of CFS will show “Unit Specific” in the Target White Level box. B. Low Level Offset: Change this setting to adjust for ambient (room) light. Most reading conditions are in relatively low room lighting and the default of 0.0 cd/m2 should be used. For rooms with bright lighting such as Operating Rooms, values of 1.5 to 2.0cd/m2 are common. C. Luminance calibration device: This should be set to “Side Bezel Sensor” to utilize the retractable front sensor built in to each display. The “Center Puck USB” (hand held puck) setting is used to facilitate calibration of supported displays that do not have a Side bezel Sensor. D. Calibration steps: The default of “0,5,10,15…” should be selected. This takes 52 measurements. Selecting smaller steps (more measurements) may slightly improve the calibration but will take much longer to complete. Selecting larger steps (0,15,30, 45…) and below is not recommended except for certain testing purposes. E. Verification steps: The default of “0,15,30,45…” should be selected. This takes 18 measurements. Selecting smaller steps (more measurements) may slightly improve the verification but will take much longer to complete. Selecting larger steps (0,15,30, 45…) and below is not recommended except for certain testing purposes. F. Check this box to perform a DICOM compliance check on all displays. G. Check this box to perform a full DICOM calibration on all displays. This will take approximately 12 to 15 minutes depending on number of displays. H. Color Point Adjustment is used to adjust color displays to specific color coordinates. Selecting this feature will reduce the maximum luminance capability of the displays and should not be used unless necessary. The specific color coordinates can be entered several ways: 1. Select the “Clear Base” box – This will preset the XY color point values to mimic the color produced by a legacy CRT display with P104 phosphor. 2. Select the “Blue Base” box – This will preset the XY color point values to mimic the color produced by a legacy CRT display with P45 phosphor. 3. Manually entered as either a Kelvin temperature value or CIE Color XY’s. Valid Kelvin values are from 5000K to 15000K. Reasonable CIE X values range between .25 and .4 and Y values between .25 and .35. 4. “Capture” with an Image Systems hand held photometer using the “Capture XY Color Point” function found on the Unit tab(s). After input of the desired color coordinates select the “Color Point Calibration” checkbox on the displays Unit Tab to adjust the color.

I. Shows the current state of each display: Unknown - new display before calibration In Full compliance – DICOM calibrated correctly, based on tolerance from Scheduler Tab. Out of Compliance – DICOM or Luminance out of compliance by more than percentage set on scheduler tab Not Attached – no display attached Note: Displays “waking up” from power saver mode may show “Not Available” for a short period of time. J. Shows current CFS revision K. CFS Network option: When CFS is used in local mode SNMP Agent will show “disabled” and Rainbow SuperPro will show “Key Not Attached”. Only for the optional Network control will SNMP Agent show “Active” and Rainbow SuperPro show “License Obtained”. L. Reacquire SNMP License: Check this box to reacquire the SNMP license. M. CFS Mode: Click this button to set a password and change to “User mode”. This will lockout most CFS parameters. Entering the password again will change to Administrator mode and allow for changes to CFS parameters.

CFS Scheduler Tab

Back Light Intensity settings: All Image Systems displays utilize an internal backlight sensor to measure the brightness of the backlights every minute. By adjusting the “Auto-adjust when off target by” setting you can control how closely the displays will maintain the Target White level luminance value set on the General Tab. Settings of 3% to 5% are typical. Should the luminance value vary more than the “Log error when off target by” setting, an error message will be logged in the Event Log and with Network CFS an error message will be sent to the SNMP management console. Typical settings are from 5% to 7%.

Starting with CFS version G7 a new improvement allows CFS to act as a Stable Backlight Control (SBC) for displays lacking this built in feature when used with AFS. This is done by setting the “Check brightness value every” to <sliding scale>. White Level Luminance: This section sets the schedule on which a White Level Luminance check will occur automatically using the Side Bezel Sensor built into each display or the AFS option. Typically this check is scheduled during off hours so as to not disrupt workflow. Common frequency settings are once per week or once per month. During the scheduled check, should the reading vary outside of the Auto adjust target (typically 3%) CFS will automatically change the White level to the Target White level luminance value set on the General Tab and log an error to the Event Log if the reading varied outside of the Log error target (typically 10%). DICOM Compliance: This section sets the schedule on which a DICOM verification check will occur. Typically this check is scheduled during off hours so as to not disrupt workflow. Common frequency settings are once per week or once per month. During the scheduled check, should the reading vary outside of the Auto adjust target (typically 5%) CFS will automatically recalibrate and log an error to the Event Log if the reading varied outside of the Log error target (typically 10%). CFS Calibration Report: Checking the “Auto-generate reports file” box will cause a calibration report to be created each time a conformance check is run. The report file is saved in /Program Files/Image Systems/Reports. The default file name is the local computer name with the current date appended to the end. The file type is HTML. The “File name” field in the “Event Log Export” section on the Preference tab sets the file name used for export of the CFS log file and the CFS Calibration Report. NOTE: If your displays are in the Windows power saver mode when a scheduled White Level Luminance or DICOM Compliance check occurs CFS will automatically power up the displays, wait 15 minutes for the displays to warm up and then initiate the check. Visual Acceptance: This section configures CFS to display a confirmation image along with an informational message on a scheduled basis. The visual confirmation image will remain on the screen for four hours or until the user confirms the image and enters their initials. See the preference tab to configure the informational message and select a confirmation image. Example Visual Acceptance image with default message.

17

Front Ambient Sensor Control: All Image Systems Professional-Series displays have a front ambient room lighting sensor. CFS receives current room lighting readings from this sensor and alerts the user should the lighting change significantly from the reading taken during the last calibration process. Should the reading vary greater than the “Display warning when brighter by” setting a pop up warning will appear. The “Check ambient LUX every” setting adjust the time interval for CFS to take readings from the Front Ambient Sensor. In the case of a pop up warning it is recommended the user either return the room lighting to the conditions set at the last calibration or re-calibrate the displays. With Image Systems M-series displays this section will be ignored. (LUX - a measure of the apparent intensity of light)

Event Log Export The CFS event log can be automatically exported to any location on the local computer on a set frequency by changing the “Export log file every” setting from Never to a desired frequency. Set the path location by typing the desire path or click the Browse for path box. The default file name is the local computer name. Selecting the Append date to file name box will append the date to the end of the file name. Purge log file after export is recommended to keep the Event Log file at a manageable size. (The Event Log will automatically truncate old entries after reaching 2048 lines) Exporting the Event log on a monthly basis is common. Visual Acceptance Popup When the Visual Acceptance Image is set or enabled on the Scheduler tab a default SMPTE image and generic message are displayed. To select a different image enter the path and file name in the Confirmation Image box. Click the “Browse for image” box to browse. GIf, Bitmap and DICOM formats are supported. To change the default message, type your desired message in the Confirmation message box. Security: SNMP License Upon a loss of connectivity to the Rainbow License server, CFS will attempt to reacquire the license on the set frequency. Attempts will continue until the license is reacquired. This setting applies only to CFS Network users. CFS activation code CFS version G4 and above requires an activation code to operate with selected graphic display adapters purchased from Image Systems. This activation code will be supplied with all effected graphic display adapters and must be entered in the CFS Activation Code box after installation. The activation code can be found on the graphic card. Graphic display adapters not requiring a code will show “N/A” in this box. After entering the supplied activation code reboot the computer. With CFS version G7 and above running with the Network CFS option the activation code is automatically entered. Reports: Selecting the “Create Reports File” action box will immediately create a current DICOM calibration status report for all Unit tabs. The report file is saved in /Program Files/Image Systems/Reports. The default file name is the local computer name with the current date appended to the end. The file type is HTML. The “Computer location/room number” and CFS Administrator” fields will be recorded in the report.

24

PnP Table: The PnP (Plug and Play) Table allows users to customize what non-Image Systems displays attached to the computer are recognized by CFS and added to the CFS calibration process. For example, by adding the Plug and Play number for a NEC 2190 to the PnP Table, CFS will add a unit tab for this display and allow calibration with either an optional AFS or the hand held Image Systems USB photometer. Only displays that support DDC communication and VESA standards for brightness control are supported. The user can also use this mechanism to instruct CFS to ignore recognized displays. Open the CFS dialog box and click on the Preference tab. Select the PnP Table button at the bottom of the window. Click inside the popup PnP table window and add the PnP number of a supported display. Now select the appropriate communication protocol for the display. After reboot CFS will add a Unit Tab for the display. Following the PnP number with a colon and 000 (example: NEC66B0: 000) will instructed CFS to ignore this display. Contact your Canvys support team for help establishing the PnP number for your display. Example PnP Table:

Auto Update Function: This option allows CFS to update to a new CFS version automatically. The latest CFS version can be found at http://teklink.canvys.com - downloads. Update one system to the new version. Copy the ISCcfs.exe file found in C:/Program Files/Image Systems/CFS folder to the path specified in the “UNC Path” setting on all other systems running CFS. At the next computer reboot CFS will check the “UNC Path” location for a new version and update automatically.

25

CFS Unit Tabs Unit Tab(s) A unit tab is created for each active display and contains important information about each display. The Device Parameters section displays information read from the attached displays internal memory. Also displayed is the current driver for the displays graphic card and last date and time of calibration of the Front Bezel Sensor along with the serial # for the Image Systems calibration puck used to last calibrate the front sensor. Calibration of the front sensor can be initiated by clicking on the “immediate action” box. To ensure accurate calibration we recommend the front sensor be re-calibrated to the Image Systems hand held USB photometer on a yearly basis.

The Color Point Adjustment section allows for color point matching of color displays. Checking the “Capture XY Color Point” box will facilitate capture of the color coordinates of the display. The coordinates are recorded on the general tab. Additional displays can now be color adjusted to these coordinates by checking the “Color Point Calibration” box. Manual section of color coordinates is also possible. See the “Color Point Adjustment” section on the general tab. The Lamp Parameters section displays information on the state of the backlights. As the backlights age the Lamp Power Level value will slowly decrease. . The Luminance Parameters section displays the target White Level for the display associated with the current unit. Changing the target value will effect only the display associated with the current unit tab. To initiate an immediate White Level check, click the corresponding immediate action box. This will activate the front sensor and check the white level. To adjust the white level, click the second immediate action box. The DICOM Parameters section displays important information about the current DICOM calibration parameters. The last date of DICOM calibration and verification along with the percentage deviation from nominal are shown. Checking the “Check for DICOM Compliance” immediate action box will activate the front sensor and start a DICOM check for compliance. To run a complete DICOM calibration process check the “Recalibrate to DICOM Standard” immediate action box. Rollback to previous DICOM Curves: Each time DICOM calibration is performed, CFS saves the previous calibration file(s). The user can choose to “rollback” to previous DICOM calibrations. Clicking on the Rollback [immediate action] box opens a list of past calibration files for the corresponding display. Example: “Dicom 050208 [0]” represents calibration file created on Feb. 8th of 2005 for the first display (Unit 1.1).

Click on box to open list of previous Dicom calibration files. Select file to “Rollback” to previous calibration.

27

Digital Uniformity Control (DUC) : This control available on the Image Systems Professional Series displays only adjusts luminance uniformity across the display to meet the DIN standard. Check the immediate action box to invoke DUC. Selecting this control will automatically switch the front sensor calibration to calibration data created with DUC ON. (Image Systems M-Series displays will ignore this control) “LOG” and “LIN” graphs: Graphs for each display found on the Unit Tab. Graph 1 “LOG” Graph 2 “LIN” Graph 1 “LOG” Shows the target versus actual luminance at each digital driving level as the mouse is moved across the graph from left to right. The ideal graph will show a straight diagonal line between the black and gray areas. Graph 2 “LIN” Shows the target versus actual JND (Just Noticeable Deference) step at each digital driving level as the mouse is moved across the graph from left to right. The ideal graph will show only small deviations (less than 4%) above and below the base line.

Displaying Test Patterns with CFS When the CFS dialog box is minimized several other CFS features can be accessed with a right mouse click on the ISC CFS icon in the tool tray (see picture below). Selecting “Test Patterns” will display a SMPTE test pattern on each grayscale display. Move the mouse to the first grayscale display and right mouse click again to select other test patterns or functions. Select “Exit” to return to normal mode. Uniformity measurements Uniformity measurement to the TG18 and DIN standards are possible with CFS using an Image Systems hand held USB photometer (puck). Plug the USB puck into a USB port and right click on the CFS icon in the tool tray. Select Uniformity and then the required Uniformity check. Follow the on screen instructions. The results of each test are displayed on the screen and recorded in a data file. The data file (c:/Program Files/Image Systems/CFS/Uniformity.CSV) can be best viewed with Microsoft Excel. . CFS with optional Add-On Front Sensor (AFS) The Add-On Front Sensor with CFS is designed to enable hands free calibration, quality checks for DICOM conformance and brightness control on selected LCD’s. CFS version G8 and above is required. Below is a list of supported displays.

Image Systems 42” (medical grade) NEC 3210, 4000, 4010, 4210, 4610, 4210 NEC 1860, 1990, 2080, 2090, 2180, 2190 Sharp PN455 Note: The supported display list continues to expand. Contact your Canvys sales or support representative for an up to date list.

30

Add-on Front Sensor (AFS) Mounting Instructions Step One: Select a location for the AFS. The best location depends on your display model. Be sure the USB connector on the AFS is accessible by the USB cable that plugs into your computer. Step Two: Select the correct mounting tape supplied with the AFS. Different displays have varying bezel thicknesses requiring different mounting tape. For best results the AFS sensor should be as close to the display glass as possible without touching. See below for suggested mounting tapes. 1/32” thick – NEC 3210, 4000, 4010, 4210, 4610, 4210 1/16” thick - Sharp PN455, NEC 1860, 1990, 2080, 2090, 2180, 2190 Step Three: Add the appropriate tape thickness required for your display to the AFS sensor. Before removing the final mounting tape backing, connect the USB cable, hold the AFS in your selected mounting location and check that the sensor does not touch the display glass. Remove the final mounting tape backing and carefully place the AFS in your selected location and press firmly. Step Four: Load the CD labeled M1 provided with you AFS in the CD-Rom drive. (installer will start – exit this program) Connect the USB cable provided between the AFS and computer. Found “New Hardware Wizard will start. Select “Install from a list or specific location (Advanced)” / Click Next. Select “Search for the best driver in these locations” / “Include this location in the search” / click Browse Select CD-Rom drive / “CFS/Software” / click OK Follow on screen instructions to complete Step Five: Install CFS G8 or above. See CFS installation instructions:

Recommended Windows Settings Screen Saver All LCD displays will exhibit some “screen retention” when an image is left on the screen for a period of time. This is easily remedied by implementing the Window Screen saver function. A moving image such as the “Beziers” with a setting of 10 to 15 minutes is recommended.

Display Power Management System (DPMS) To extend the life the backlight bulbs the Windows DPMS function is encouraged. A setting from 20 to 60 minutes is recommended.

33

Desktop Wallpaper To minimize “screen retention” issues, setting the Desktop Wallpaper to “none” is recommended. Visual Effects option in Windows XP: This Windows option adjusts grayscale shading and may have an adverse effect on DICOM calibration. It is recommended that this option be set to “Best Performance”. Open “Control Panel” / System / Click the “Advanced” tab / Select Performance Settings / Select the option “Adjust for best performance” / Click Apply Trouble Shooting Front Sensor stuck in the out position: On rare occasions such as a power failure or mechanical problems the retractable front sensor could get stuck in the out position. Should this happen DO NOT manually force the sensor back in! Open the CFS dialog box and select the Unit tab for the display with the stuck sensor. Check the “Check White Level Luminance” [immediate action] box, and then click abort. The front sensor should retract. If the sensor does not retract please contact your service representative. CFS icon does not appear in the tool tray after reboot: CFS is designed as a Windows service with a dependence to SNMP. CFS will not start unless the SNMP service is installed and started. The Quick Install Instructions describe the procedure to install SNMP. If after correctly installing SNMP the CFS service does not start please contact your service representative. Event Log shows DICOM or Luminance maintenance bypassed: Probable cause is the Bezel (Front Sensor) is not calibrated or DICOM calibration was not run at initial install (see install instructions to calibrate front bezel sensor or run DICOM calibration). Calibration puck driver problem / “The Specified Sensor is not responding”: On rare occasions the driver for the hand held calibration puck can become corrupted. Sometimes simply plugging the puck into another USB port will remedy the problem. A system reboot may also work. If problem still persist the driver may need to be reinstalled. Open the “Unplug or Eject hardware” icon from the tool tray. Click on properties and then the driver tab. Click on uninstall and then close. Unplug the puck from the USB port and then reinsert into same USB port. The Found New Hardware Wizard will start. Click next / Select “Search for a suitable driver…..” (default) Click Next. Select “Specify a location” only. Click Next. Browse to C:\Program Files\ImageSystems\Support Files\ Click Ok / Next / and Finish.

Popup window with 30 day warning appears at boot up: CFS activation code not entered or entered incorrectly. See the Preference Tab section for instructions on entering the CFS activation code.

Look for this document packaged with the graphic card supplied by Canvys. CFS Unit Tabs not present (CFS in simulator mode): Three scenarios will cause CFS to default to simulator mode.

1. None of the connected displays are configured in the PnP Table and support DDC communication.. 2. The CFS activation code was not entered and the 30-day trial period has expired.

Check security section on the Preference Tab of CFS. Make sure the activation code was entered.

3. The graphic controller card is not an approved card from Canvys. Contact your Canvys representative. CFS Unit tab missing (two displays connected but only one tab present): Try unplugging power to the display not being recognized, reconnect, and reboot the computer. If this does not correct the situation the graphic card drivers may not be installed correctly. Contact your service representative for help installing the graphic card drivers. SNMP Agent is “Not Active”: During initial CFS startup the SNMP Agent may take up to 2 minutes to become active. If SNMP Agent is still “Not Active” after 2 minutes check that the SNMP service is installed correctly (see installation instructions). If problem persist re-install CFS software. Rainbow SuperPro “Key not Attached”: This is normal when using CFS in local mode. Only for the optional Network control will Rainbow SuperPro show “License Obtained”. Check that the Dongle is connected, Rainbow software is installed and the Windows system variable NSP_HOST is configured correctly (see install instructions).

Attention SAVE!!! After installing this video display adapter and CFS (Calibration Feedback System) you must enter the following code in the “CFS Activation Code” window on the Preference tab of CFS.

Video Card S/N: _______________ Activation Code:_______________ (case sensitive)
