2. Notes for Using the Instrument
Digital camera
• The digital camera installed on the Digital Retinal Camera CX-1 is designed for the CX-1.
• The specifications differ from the typical commercially-available Canon digital cameras. It cannot be
used for purposes other than observing and taking photographs of peoples’ eyes. Do not use the digital
camera removing from the retinal camera body. This can damage or harm the performance of the
instrument.
• If any problems with the digital camera occur or repairs are needed, please contact a Canon
representative or distributor.
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.
• Do not touch the lens part of the retinal camera and the mirror part of the digital camera when attaching
and detaching the digital camera from the retinal camera body. If any dirt, fingerprints, dust, and other
foreign objects attaches to the lens or mirror part, you cannot take a good image.
• Be sure to adjust the diopter of the viewfinder so it matches the diopter of photographer’s eye.
Otherwise, focusing will not be able to be performed correctly.
After use
• Turn OFF the power of the instrument. Place the cap over the objective lens, and place the dust cover
over the instrument. You cannot take a good picture when the objective lens is dirty.
• If the digital camera is removed and left unattached, dust and other foreign objects can enter the retinal
camera and the digital camera. Be sure to always attach the caps to the respective mounts.
Cleaning and disinfection
• Do not let the tip of a blower touch the objective lens.
• Do not wipe off or rub the objective lens when there is dust or other substances on it.
This could scratch the lens surface.
• Never wipe the objective lens with disinfecting ethanol, eyeglass lens cleaner, or cleaning paper
containing silicon. The lens surface could be damaged or the surface may not be completely wiped off.
• Do not clean the cover of the instrument with lens cleaner. The cover of the instrument could be
damaged.
