sets (Models 5110N, 5110E, 5111N, 5112N).
Device Description and Intended Use
Ophthalmoscope attachment (5110N, 5110E, 5112N)
The ophthalmoscope is a hand held, battery-powered device containing illumination and viewing optics
intended to examine the media (cornea, aqueous, lens, and vitreous), the retina, blood vessels, optic
nerve, and other structures o the eye. It is intended to be used by a trained healthcare pro essional.
Otoscope Attachment (5110N, 5110E, 5111N)
A handheld battery powered device with magni ying system that provides illumination o the ear canal
and tympanic membrane.
Latex Statement This device and all accessories are latex ree.
This device should be used by a trained healthcare professional.
Contraindications
The use o this device is contraindicated in patients who have already received prolonged or intense
light exposure, especially i the patients are in ants, aphakes, or persons with diseased eyes. Excessive
exposure to light may result in patient injury. See warnings or additional in ormation.
General Warnings
A warning statement in this manual identifies a condition or practice which, if not cor-
rected or discontinued immediately, could lead to patient injury, illness, or death.
CAUTION: Because prolonged intense light exposure can damage the retina, the use o the device or
ocular examination should not be unnecessarily prolonged, and the brightness setting should not
exceed what is needed to provide clear visualization o the target structures.
The retinal exposure dose or a photochemical hazard is a product o the radiance and the exposure
time. I the value o radiance were reduced in hal , twice the time would be needed to reach the maximum
exposure limit.
While no acute optical radiation hazards have been identi ied or direct or indirect ophthalmoscopes,
it is recommended that the intensity o light directed into the patient's eye be limited to the minimum
level which is necessary or diagnosis. In ants, aphakes and persons with diseased eyes will be at
greater risk. The risk may also be increased i the person being examined has had any exposure with
the same instrument or any other ophthalmic instrument using a visible light source during the previous
24 hours. This will apply particularly i the eye has been exposed to retinal photography.
CAUTION: Do NOT immerse the battery handle in liquid. Consult the cleaning and disin ection in-
structions or each part or urther in ormation about cleaning and disin ecting this product. Never clean
or disin ect any device with batteries in it.
CAUTION: Federal law restricts this device to sale by or on the order o a physician or licensed health-

Cleaning and Disinfection
Basic Cleaning Procedure for Battery Handles, Otoscope and Ophthalmoscope Heads
To clean the exterior o the device, prepare a 70% isopropyl alchohol solution and soak a lint- ree
cloth. Wipe down the exterior o the ophthalmoscope head and handle, cleaning all external sur ace
areas. Care should be taken to prevent excess liquid rom seeping into the components.
Isopropyl alchohol may be substituted with commonly used, EPA-registered hospital disin ectant
wipes or cleaning purposes i desired. Please re er to the directions provided by the manu acturer o
the wipes or appropriate instructions or use to ensure e ective contact time between the wipe and the
device.
It is important to note that solution residue on the magni ying lenses may decrease device per orm-
ance. All excess cleaning luids must be care ully wiped clean i these sur aces are cleaned. The lenses o
the instrument head may be cleaned with a lint- ree cloth or lens paper.
