Appropriately power down and unplug the unit and allow the light source bulb to cool before replacing it. Refer to the instructions to Replace Illumination Lamp as necessary. 8. Never connect the RetCam II to a network or any externally powered devices or peripherals during imaging. 9. Before using this equipment to acquire images from patient eyes, users must be trained in proper clinical technique by personnel authorized by Clarity. 10. The RetCam II is for use by or on the order of a health care professional. 11. It is possible that during Electrical Fast Transients from the AC line, the system’s display may scroll continuously. This is an indication that the source of AC power has electronic disturbance (transients). If this indication is present, imaging should not proceed until the disturbance has ceased: the AC plug is put into a different AC outlet: or RetCam II is run from the UPS. If the disturbance persists, an error message may be displayed, which then may require a system reset. Toe perform a system reset, press the (I/O) power switch on the control panel for approx 6 seconds until the system powers down, then press the (I/O) button again to power the system back on . THIS DOES NOT PRESENT A SAFETY RISK TO THE PATIENT, USER, OR ENVIRONMENT

The system is provided with the means to easily move it between operations or between beds in the NICU while it is running. To relocate the system while it is running, disconnect the power cord at both ends, release the front caster locks and gently roll the system to the new location. 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. If the floor is uneven or tiled surface, move the system carefully to avoid damage from excessive vibration. The system is not intended to be transported outdoors from building to building. For information on how to safely transport the system out of doors or in anything but an upright position, please contact Customer Service. The RetCam II 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. Inspection and testing of the system by a factorytrained technician after transport outdoors or in a non-upright configuration is necessary to insure continued compliance with all safety standards.
System Description The RetCam II 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. (Ref. Figures 1 and 2)
1) Display: A high resolution LCD flat panel display is standard with the system. 2) 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). 3) Handpiece: The handpiece contains the actual 3-chip CCD. It is light weight and easy to use. The front lens pieces are removable, and allow quick and easy exchange. 4) 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. 5) Light Box: The light box contains a CCD camera control unit, a halogen illumination light, and the control circuitry for light intensity, focus, image capture and system logic. 6) Computer: The computer is controlled by a keyboard and trackball. It is a Pentium4 based system, running a specialized Embedded Windows XP, with two internal DVD storage drives and media and proprietary software. The system has an integrated network adapter, and USB hub. 7) Uninterruptible Power Supply (UPS): The computer, display and optional image printer are powered by an Uninterruptible Power Supply. The UPS helps to protect against accidental 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. 8) Footswitch: The footswitch is a rocker style unit with a function switch on each side, and a push button in the middle. The pedal on the left side controls focusing. Rock this pedal to the left to focus closer, and to the right to focus more distant. The pedal on the right controls illumination light intensity. Rock this pedal to the left to decrease intensity and to the right to increase intensity. The push button in the middle is called the snap switch. An image is captured and stored each time the snap switch is depressed. In video mode, this switch can be used to alternately start and stop video recording. 9) Power Conditioner: The power conditioner isolates the RetCam system from power/line disturbance and meets medical electrical device safety requirements. 10) Storage Drawer(s): One storage drawer is supplied on all units for lens pieces, DVDRAM’s and accessories. Without the Fluorescein Angiography light source, an additional drawer is furnished for extra storage. 11) Report Printer (option): A high resolution inkjet printer can print reports on 8.5” x 11” paper. 12) Image Printer (option): The high quality Mitsubishi dye-sublimation printer can print single images of 3.75” x 4.75” or two images one above the other in a smaller size. 13) Fluorescein Angiography Source (option): A blue exciter light source is available complete with green barrier filter for the handpiece for doing F.A. digital photography with the RetCam II.

Cleaning Procedures
For cleaning purposes, the RetCam II is divided into two categories: 1. The Lens Piece that contacts the patient 2. The rest of the system 3.2.1
The Lens Piece
The Lens Piece should be cleaned thoroughly between patients to prevent the spread of infectious disease. As recommended by the American Academy of Ophthalmology, the cleaning liquid of choice is 70% isopropyl alcohol. Moisten a clean towelette with the solution and use a gentle wiping action across the front of the lens piece, being sure to pay special attention to the concave contact lens area. To prevent irritation to the next patient from residue left on the lens, rinse the tip of the lens piece thoroughly with disinfected distilled water.
Warning: To avoid damage, do not autoclave any part of the RetCam II system. The American Academy of Ophthalmology also recommends disinfecting with 1:10 dilution of bleach for 5 minutes.(refer to page inserts following this page). .
