The instrument parts that routinely contact the patient—the forehead and chinrests—
should be cleaned between each examination with an alcohol prep wipe. These parts are
not removable.
To remove dust and oily smudges from the external surfaces of the instrument, periodically
clean plastic covers and housings with an alcohol prep wipe, and dry with a soft, non–
linting cloth.
CAUTION: Alcohol prep wipes may damage glass lens components of the imaging
aperture and external lenses. Do not use alcohol prep wipes to clean glass lenses.
To clean the glass lens components of the imaging aperture and external lenses, use the
dry camera lens wipes (2660100007673) and camera lens cleaner (2660100007672)
listed in
"User Replacement Accessories" on page
the camera lens cleaner to the dry lens wipe and gently clean the lens.
If a patient's eye inadvertently contacts any part of the imaging aperture or an external
lens, clean the imaging aperture or the external lens before proceeding with the
examination.
CAUTION: Wipe gently and carefully to avoid scratching the instrument and auxiliary
lenses.
Clean the LCD screen when necessary to remove dust and oily smudges that impair
viewing. Turn off the monitor first. We recommend that you use a soft cotton cloth; if a dry
cloth does not completely clean the screen, you can dampen the cloth with water only and
wipe the screen with the damp cloth.
Periodically, inspect the top fan filter located under the removable cover on top of the
