•  The attached digital camera is designed for the CR-2 AF. The specifications differ from 

commercially available Canon digital cameras. Use only for observing and taking photographs of 
peoples’ eyes. Do not detach the digital camera from the main unit to use separately. Otherwise, 
failure of the CR-2 AF may result.

•  If any problems occur or repairs are needed with the CR-2 AF’s digital camera, contact your sales 

representative or local Canon dealer.

•  Inspect the CR-2 AF daily. Make sure that no foreign matter is present that can affect image 

readings or diagnoses. 

•  Check and clean the objective lens before taking an image. Any stains or scratches on the 

objective lens will appear as white spots. 

•  Sudden heating of a room during winter or in cold regions may cause condensation to form on 

the objective lens or on optical parts inside the CR-2 AF. In this case, wait until condensation 
disappears before taking images. 

•  Do not touch the lens of the retinal camera or the mirror of the digital camera when attaching and 

detaching the digital camera from the retinal camera. If any dirt, fingerprints, dust, or other foreign 
objects are on the lens or mirror, you will not be able to take a good image.

•  After using the CR-2 AF, turn off the power, cover the objective lens with the objective lens cap to 

protect it from dust, and place the dust cover over the CR-2 AF. You cannot take good images if 
the objective lens is dusty. 

•  If the digital camera is detached and left unattached, dirt and dust may enter the retinal camera 

and the digital camera. Be sure to always attach the caps to their respective mounts.

•  Do not allow the blower to touch the lens. 

•  Do not wipe or rub the lens if there is dirt or dust on it. Doing so could scratch the lens. 

•  Do not wipe the lens with disinfectant ethanol, eyeglass cleaner, or silicone-coated paper. Doing 

so could corrode the surface of the lens or leave streaks. 

•  Do not clean the outside of the CR-2 AF with a lens cleaner. Doing so could damage the outside 

of the CR-2 AF. 

•  Never use alcohol, benzine, thinner, or other solvents to clean the outside of the CR-2 AF. Doing 

so damages the outside of the CR-2 AF. 

•  Never use disinfectant ethanol to clean the outside of the CR-2 AF, with the except of the forehead 

rest and the chin rest. Doing so damages the outside of the CR-2 AF. 

•  If the chin rest paper is not being used, disinfect the chin rest for each patient in the same manner 

as you do for the forehead rest.

•  Carry out all cleaning, sterilization and disinfection procedures specified in the instruction manual 

for each peripheral device in the system.
