1. Features The Canon CR-1 digital retinal camera is used to take digital photographic retinal images of patient’s eyes across a wide range (photographic angle of view of 45 degrees) in a naturally dilated state without the use of mydriatics. It has the following features. Compact size and superior operability Compact dimensions and a light weight. Since the main unit can be raised and lowered by the operation lever, and the chin rest became motordriven, the alignment procedure has dramatically improved.
2. Notes for Using the Instrument Before Use • Check and clean the objective lens before taking an image, as any stains or scratches on it will appear as white spots. • Sudden heating of the room in cold areas will cause condensation to form on the objective lens or on optical parts inside the instrument. In this case, wait until condensation disappears before performing photography.
2. Notes for Using the Instrument Environment of Use • Do not install or store the camera or leave it standing in an adverse environment such as where the temperature and humidity levels are high. Doing so may cause trouble and/or malfunction. Be sure to observe the points on page (7) when selecting the installation location. • Dust in the air will not only attach to the objective lens, but will also attach onto the optical parts inside the instrument. You cannot take a good image when dust is on them.

Use the control software to input the study information.
4. Operation 4.2 Adjusting the Position and Focusing 1 Have the patient sit down. Have the patient place his or her chin against the chin rest and his or her forehead against the forehead rest. 2 Align the height of the patient’s eye. Move the chin rest up or down so that the patient’s eye is aligned with the height adjustment mark by operating the CHIN REST switches. Height adjustment mark 3 Display the patient’s eye to be photographed on the monitor.
4. Operation 4 Align the position of the pupil. ! CAUTION When adjusting the position of the main unit in the front-back direction, slowly bring the main unit closer to the patient while looking at the patient’s eye from the side. You may injure the patient’s eye if the objective lens makes contact with it. ! CAUTION Do not put your fingers or hands between the sliding part and base of the stage unit . Similarly, do not allow patients to put their hands in these places.
4. Operation Concerning the SP function Use the SP (small pupil photography) function if the pupil of the patient’s eye fails to become larger than the inside pupil position alignment mark even after waiting for a while in the darkened room. This function enables pupils with a diameter down to 3.7 mm to be photographed. (1) Press the SP switch on the operation panel. (2) Press the ALIGNMENT switch, and display the retinal image on the monitor. The photography range is now R displayed.
4. Operation 5 Display the retina observation screen. Press the ALIGNMENT switch. The internal eye fixation lamp flashes for 3 seconds. R Note: When the stage unit is slid toward the other eye on the retina observation screen, the anterior eye observation screen is displayed. Concerning the stereo mode The stereo mode can be set to ON or OFF using the [Set menu] .Refer to 5. Settings (see page 21). When this mode is ON, “STEREO” is displayed on the observation screen.
4. Operation 8 Decide on the area to be photographed. Have the patient stare at the green internal eye fixation lamp. If necessary, while viewing the monitor, press the FIX TARGET switch to move the internal eye fixation lamp, and guide the patient’s eye. The internal eye fixation lamp moves up and down and toward the left and right.
4. Operation 10 Bring the eye into focus. Turn the focus knob and align the split lines into a single straight line. Split lines Working distance dots In the event of the following: When the split lines are not visible: If this is the case, refer to 6.2.1 Troubleshooting (see page 26). When the split lines are not aligned into a single straight line: If the split lines are not aligned: Use the diopter compensation lever to insert the diopter compensation lens, and take the photographs.
4. Operation Note: When operating the diopter compensation lever, set it precisely to the 0, “–” or “+” position. If the lever is set to a position midway between two settings, fundus images will not be taken properly. 11 Adjust the position of the retinal image. Tilt the operation lever forward or backward so that the left and right working distance dots are made as small as possible.
4. Operation 4.3 Photography 1 Take a photograph. Check that the photography status display is green. In a flare-free status, check the focus again, and press Shutter release button the shutter release button. A retinal image is now taken, and the anterior eye observation screen is displayed. However, the retina observation screen will remain on the monitor if the stereo mode is established.
4. Operation 2 Review the image. The fundus images and study information are displayed in the control software. Check the images. When the images taken are not clear If this is the case, refer to 6.2.1 Troubleshooting (see page 26). 3 Now take a photography of the other eye. Taking photographs of one eye will cause the pupils of both eyes to contract excessively. Wait at least 5 minutes, and check that the pupils have dilated.
