Routine Cleaning
12-3
Forehead and Chinrests
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.
External Surfaces of the Instrument
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.
Imaging Aperture Lens and External 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 12-5 . Apply a small amount of
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.
LCD (Monitor) Screen
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.
Top Fan Filter
Periodically, inspect the top fan filter located under the removable cover on top of the
instrument (
Figure 12-1 ). The filter should be checked, at least, twice a year; in dusty
environments, more frequently. Push on the snap connector and pull the cover back and
up. It will swing open and can then be easily removed.
