Notes on Using CR-2 Plus AF
Digital camera
t The attached digital camera is designed for the CR-2 Plus 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 Plus AF may result.
t If any problems occur or repairs are needed with the CR-2 Plus AF’s digital camera, contact your
sales representative or local Canon dealer.
Before use
t Inspect the CR-2 Plus AF daily. Make sure that no foreign matter is present that can affect image
readings or diagnoses.
t Check and clean the objective lens before taking an image. Any stains or scratches on the
objective lens will appear as white spots.
t 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 Plus AF. In this case, wait until condensation
disappears before taking images.
t 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 use
t After using the CR-2 Plus AF, turn off the power, cover the objective lens with the objective lens
cover to protect it from dust, and place the dust cover over the CR-2 Plus AF. You cannot take
good images if the objective lens is dusty.
t 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.
Cleaning and disinfection
t Do not allow the blower to touch the lens.
t Do not wipe or rub the lens if there is dirt or dust on it. Doing so could scratch the lens.
t Do not wipe the lens with an ethanol solution, eyeglass cleaner, or silicone-coated paper. Doing so
could corrode the surface of the lens or leave streaks.
t Do not clean the outside of the CR-2 Plus AF with a lens cleaner. Doing so could damage the
outside of the CR-2 Plus AF.
t Never use alcohol, benzine, thinner, or other solvents to clean the outside of the CR-2 Plus AF.
Doing so damages the outside of the CR-2 Plus AF.
t Never use an ethanol solution to clean the outside of the CR-2 Plus AF, with the except of the
forehead rest and the chin rest. Doing so damages the outside of the CR-2 Plus AF.
t 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.
t Carry out all cleaning, sterilization and disinfection procedures specified in the instruction manual
for each peripheral device in the system.
