be turned OFF when not in use. If storing for extended lengths of time, remove batteries
completely.
Handle Care and Maintenance

dation. Always replace BOTH batteries. Alkaline batteries are recommended. Remove batteries from han-
dle if instrument will not be used for an extended period of time.
Cleaning and Disinfection
Basic Cleaning Procedure for Battery Handles, Otoscope and Ophthalmoscope Heads
To clean the exterior of the device, prepare a 70% isopropyl alchohol solution and soak a lint-free
cloth. Wipe down the exterior of the ophthalmoscope head and handle, cleaning all external surface
areas. Care should be taken to prevent excess liquid from seeping into the components.
Isopropyl alchohol may be substituted with commonly used, EPA-registered hospital disinfectant
wipes for cleaning purposes if desired. Please refer to the directions provided by the manufacturer of
the wipes for appropriate instructions for use to ensure effective contact time between the wipe and the
device.
It is important to note that solution residue on the magnifying lenses may decrease device perform-
ance. All excess cleaning fluids must be carefully wiped clean if these surfaces are cleaned. The lenses of
the instrument head may be cleaned with a lint-free cloth or lens paper.
