Introduction 11
1 Introduction The RetCam II Wide Field Imaging System (system) is designed using state-of-the-art digital technology to allow the quick and easy capture of wide field, high resolution, fully digital images and videos of the eye. The RetCam system consists of several modules mounted in a stable, high quality integrated mobile cart for easy, safe transportation from one location to another within the hospital or clinic. It also offers enhanced networkability, to support data transfer to and from the system and sharing data with other RetCam systems. The system is designed for easy operation by either a clinician or trained staff members. Using the integrated computer, you have point-and-click access to all functions via the system software. You can use the RetCam II to quickly capture, display, process, and transfer high resolution digital images.
Indications for Use For general ophthalmic imaging, including retinal, corneal, and external.
Purpose and Organization of this Manual This manual serves as a usage and reference guide for the RetCam II. It first provides introductory and safety information (Chapter 1 Introduction), and then system level information (Chapter 2 System Functions, page 28). It is then organized according to the expected sequence of use, as follows: • Chapter 3 Start, Patient Select, New Session, page 46 • Chapter 4 Review and Compare Images, page 69 • Chapter 5 Process Images, page 76 • Chapter 6 Data Transfer, page 84 • Chapter 7 Utilities, page 107 Succeeding chapters cover Maintenance and Support, Specifications and License Agreements. Finally, this manual provides an Index to assist you with finding desired information. The Introduction covers the following topics: • System Hardware, below • Software Overview: RetCam II Screens and Functions, page 16 • Storage, page 19 • Transport, page 19 • Electrical Safety Information, page 19 • FDA (USA) Notices, page 23 • Important User Safety Notices, page 23

System Hardware The RetCam system consists of several modules mounted in a stable, high quality integrated mobile cart for easy, safe transportation from one location to another. The front pair of lockable casters allow for easy maneuverability and positioning, while the fixed rear wheels guide the unit in a straight line during transport. Figure 1 and Figure 2 below illustrate the system hardware. WARNING: Unauthorized modifications or additions to the software or hardware of the system will void the warranty and could adversely affect the system function.

14 Introduction
Hardware Components • Display: A high resolution LCD flat panel display is standard with the system. • Control Panel: A membrane control panel turns the system on with one button, and has controls for illumination intensity, camera focus and snap (capture an image or start/stop video recording). • Handpiece: Contains the 3-chip CCD camera. Lightweight and easy to position, it has a long cable for easy reach. Use with 5 changeable lens pieces. (See details in Figure 2 and Figure 3.) Always return the handpiece to the holster on the work surface when ☞ Note: not imaging. The handpiece cable can be draped over the side support, but do not wrap it tightly or damage to the fiber optic may result. • Interconnect Cable: The interconnect harness contains three separate cables, the fiber optic for transmission of illumination light, the camera cable, and the focus motor control cable. • Light Box: Contains the CCD camera control unit, a halogen illumination lamp, and the control circuitry for light intensity, camera focus, image capture and system logic. The front panel has connectors for the Handpiece (camera), the Fiber Optic (halogen lamp), the Focus controller and S-video Out. (See The Light Box on page 37 for more details.) • Computer: The computer is controlled by an integrated keyboard and trackball. It is a Pentium4 based system, running a specialized Embedded Windows XP, with two internal DVD-RAM storage drives and proprietary software. The system has an integrated network adapter and USB hub. • Uninterruptible Power Supply (UPS): The computer, display and optional image printer are powered through an Uninterruptible Power Supply. The UPS protects against loss of images due to power surges or sudden power loss. The UPS can store enough energy to power the computer and display for several minutes, allowing the system to be unplugged from the electrical outlet and moved from room to room or bed to bed without having to reboot the system. • Footswitch: A rocker pedal on each side, and a push button in the middle. • Focus control-left pedal: Rock to the left to focus closer, to the right to focus more distant. • Light intensity-right pedal: Rock to the left to decrease intensity, to the right to increase intensity. • Snap switch-central push button: Press to capture and store the current still image, or in video mode, to start and stop recording. • Power Conditioner: The power conditioner isolates the RetCam system from power/line disturbance and meets medical electrical device safety requirements.

Introduction 15 • Storage Drawer(s): All units have at least one storage drawer for lens pieces, DVD-RAMs, tools and supplies. Units that do not include the optional Fluorescein Angiography light source have an additional storage drawer. • Fluorescein Angiography Source (optional): An optional blue exciter light source is available for doing FA digital photography with the RetCam II. It comes complete with a yellow barrier filter for the handpiece. Lens piece

Storage Always return the handpiece to the holster on the top surface when not ☞ Note: imaging. The handpiece cable can be draped over the side support, but do not wrap it tightly or damage to the fiber optic may result. For storage of the system when not in use: 1. Remove all loose objects from the top surface. 2. Fold the display down flat. 3. Wipe down the surfaces with a soft cloth. 4. Place the dust cover over the system. 5. Lock the casters to keep it in place.
Transport The system is provided with the means to easily move it between operatories or between beds in the neonatal intensive care unit while it is running. The system is not intended to be transported outdoors from building to ☞ Note: building. For information on how to safely transport the system out of doors or in anything but an upright position, please contact the factory. The RetCam II System has been designed, inspected and tested to comply with the safety requirements of IEC60601-1 with respect to fire, shock and mechanical hazards only if used as intended. To relocate the system while it is running: 1. If necessary, exit out of the New Session screen so that live video is not running. 2. Disconnect the power cord at both ends. 3. Release the front caster locks. Now you can gently roll the system on all four wheels to the new location. If the floor is an uneven or tiled surface, move the system slowly to reduce damage from excessive vibration. The internal power supply will keep the computer and monitor running for several minutes. Once in the new position, lock the casters, reconnect the power cord at both ends and continue with imaging.
Electrical Safety Information The RetCam II System has been designed, inspected and tested to comply with the safety requirements of IEC60601-1 with respect to fire, shock and mechanical hazards only if used as intended.
