GENERAL SAFETY INFORMATION
CONTRAINDICATION
This instrument must not be used for the following patients:
• Patients who are hypersensitive to light.
• Patients who recently underwent photodynamic therapy (PDT).
• Patients taking medication that causes photosensitivity.
WARNING
Ensuring the Safety of Patients and Operators
Use this instrument carefully on the following patients.
• Patients who have epidemic corneitis, conjunctivitis or any other infectious disease.
• Patients who are taking medications that cause light hypersensitivity.
To avoid injury to the patient’s eye and nose, pay particular attention while operating the instrument
body. (The patient may be injured.)
The Topcon SL-D301 is a medical device. The software and hardware has been designed in accordance with U.S., European and other international medical device design and manufacturing standards. Unauthorized modification of the Topcon SL-D301 software or hardware, or any addition or
deletion of any application in any way can jeopardize the safety of operators and patients, the performance of the instrument, and the integrity of patient data.
Because prolonged intense light exposure can damage the retina, the use of the device for ocular
examination should not be unnecessarily prolonged, and the brightness setting should not exceed
what is needed to provide clear visualization of the target structures.
The retinal exposure dose for a photochemical hazard is a product of the radiance and the exposure
time. If the value of radiance were reduced in half, twice the time would be needed to reach the maximum exposure limit.
While no acute optical radiation hazards have been identified for direct or indirect ophthalmoscopes, it
is recommended that the intensity of light directed into the patient's eye be limited to the minimum level
which is necessary for diagnosis. Infants, aphakes and persons with diseased eyes will be at greater
risk. The risk may also be increased if the person being examined has had any exposure to the same
instrument or any other ophthalmic instrument using a visible light source during the previous 24 hours.
This will apply particularly if the eye has been exposed to retinal photography.
Equipment is not suitable for use in the presence of a Flammable Anesthetic Mixture with Air, Oxygen,
or Nitrous Oxide.
The Topcon SL-D301 has no special protection against harmful ingress of water or other liquids (classified IPX0). To avoid damage to the instrument and cause a safety hazard, the cleaning solutions,
including water, should not be directly applied to the device. Using a dampened cloth (without dripping), is a good method to clean the exterior surface of the enclosure.
Handling the cord on this product or cords associated with accessories sold with this product, will expose
you to lead, a chemical known to the State of California to cause birth detects or other reproductive harm.
Wash hands after handling.

Preventing Electric Shock and Fire.
To avoid fire in the event of an instrument malfunction, immediately turn off the power switch and
remove the power plug from the outlet if you see smoke coming from the instrument or if you detect
other problems. Don't install the instrument where it is difficult to disconnect the power plug from the
outlet. Ask your dealer for repairs.
CAUTION
Ensuring the Safety of Patients and Operators
Be careful not to let the patient touch this instrument. The patient's hand may be pinched by a movable
part.
To avoid burns caused by heat, do not replace the lamp with a new one immediately after it goes off.
To avoid injury to the patient's head, incline the illumination unit slowly while holding the base unit.

Preventing Electric Shock and Burn
To avoid injury or fire caused by electric shock, turn off the power switch and unplug the power cord
when not in use.
To avoid injury caused by electric shock, turn off the power switch when replacing the lamp.
Electromagnetic Compatibility (EMC)
This instrument has been tested (with 100/120/230V) and found to
2007as class B(classified according to CISPR11).
This instrument radiates radio frequency energy within standard and may affect other devices in the
vicinity.
If you have discovered that turning on/off the instrument affects other devices, we recommend you
change its position, keep a proper distance from other devices, or plug it into a different outlet.
Please consult your authorized dealer if you have any additional questions.

OPTICAL RADIATION HAZARD
• The light radiated from the instrument is potentially hazardous. The
longer the exposure time is, the higher the risk of causing disorder to

the eye is.
• When operating with the maximum intensity, the light radiation
reaches values exceeding the safety guideline in about 309 sec.
Because prolonged intense light exposure can damage the retina, the use of the device for ocular examination
should not be unnecessarily prolonged, and the brightness setting should not exceed what is needed to provide
clear visualization of the target structures.
The retinal exposure dose for a photochemical hazard is a product of the radiance and the exposure time. If the
value of radiance were reduced in half, twice the time would be needed to reach the maximum exposure limit.
While no acute optical radiation hazards have been identified for slit lamps, it is recommended that the intensity
of light directed into the patient's eye be limited to the minimum level which is necessary for diagnosis. Infants,
aphakes and persons with diseased eyes will be at greater risk. The risk may also be increased if 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 if the eye has been exposed to retinal
photography.
