! WARNING
1. Do not disassemble this product.
Do not disassemble this product. Doing so may result in electric shock or failure. Any failure or
damage caused by such action will not be covered under warranty.
Never attempt to disassemble any part of this product unless you are instructed to do so in this
manual. If there is a problem with this product, contact your Nikon representative.
2. Use the AC adapter supplied with the product.
An AC adapter is used to supply power to this product. Be sure to use the AC adapter supplied with
this product.
The AC adapter input is rated for 100-240 V AC, 50/60 Hz. It can be connected to an AC socket
with various voltages. However, do not use this product in an environment where the supply voltage
varies widely.
3. Use the specified power cord.
Use only the specified power cord when connecting the AC adapter to an AC power supply.
Use of any other power cord may cause malfunction or overheating of this product, or fire. This
product is classified as a Class I electric shock protection device, designed to be connected to an
AC socket that has a protective ground terminal.
• Refer to Chapter 6, “Specifications” for the power cord specification.
• When plugging in the power cord, to minimize the risk of electrocution, make sure that main
power switch of the device is off (set to the “O” side).
4. Ultraviolet light radiation
When lit, this product radiates ultraviolet light that can damage the eyes and skin. Do not view light
coming from the product. Direct viewing of the light might result in blindness.
5. Do not block the vents on the product.
Ensure that the vents on the top and bottom of the main body of the product remain unobstructed.
Do not place objects on the project, and do not cover it with anything. Doing so may inhibit heat
dissipation and cause overheating.
6. Photobiological safety
This product is designed and manufactured in compliance with the “Photobiological safety of lamps
and lamp systems” (IEC62471) specified by IEC.
The photobiological safety for the light emitted from this product is classified in the following risk
groups:
The following table shows the distance (hazard distance) from the aperture when the risk group
classification is the Exempt Group, which does not cause photobiological hazards:
Risk group classification Hazard distance
UV hazard Risk group 3 0.9 m or more
Retinal blue-light hazard Risk group 2 4.1 m or more
7. Do not look into the LED light.
A WARNING label indicating photobiological safety (as shown below) is attached near the
light-emitting hole of this product (see the figure in Chapter 1, “Names of Parts” for the location of
the label) to call the attention to the following:
• When the LED is turned on, a strong light is emitted from the light-emitting hole. Never look into
the LED while the LED is turned on. LED illumination is hazardous to your eyes.

! CAUTION
1. Shut down the power
When you assemble or clean this product, or plug or unplug cables, to minimize the risk of
electrocution or product failure, make sure that the main power switch of the main body is off (set to
the “O” side) and the power cord of the AC adapter is disconnected from the power socket.
When plugging in the AC adapter, make sure that the power switch of the main body is off (set to
the “O” side).
2. Do not allow this product to become wet. Do not allow any foreign material to enter this
product.
Do not allow this product to come into contact with water or any chemical solution. Spilling water o
r
chemical solution over this product may short-circuit the product and cause failure or overheating.
Similarly, if any foreign material enters the product, the product may short-circuit.
In the event that water or chemical solution is spilled over the product, immediately turn off the main
power switch (set it to the “O” side), and then disconnect the AC adapter (at this point, pay attention
not to touch the product with wet hands). Then, wipe the moisture off the product by using a dry
cloth, etc.
In the event of ingress of water or foreign matter, stop using this product and contact your nearest
Nikon representative.
3. Do not place objects on the product.
Do not place any objects on the product.
In particular, placing a heavy object may cause deformation, damage, or failure of this product.
Never place an object on the product as it may also fall and cause injury.
4. Do not turn on the product while it is covered.
Do not turn on the product while it is covered (with a cover or cloth, for example). Doing so may
inhibit heat dissipation, leading to malfunction or fire due to overheating. Additionally, do not cover
this product with a cloth, etc., during operation. Doing so may raise the temperature inside the
product, and lead to failure.
5. Cautions when assembling the product
When attaching this product to an epi fluorescence attachment or microscope system, be careful
not to injure your fingers or hands.
6. Cautions when cleaning the product
• Do not attempt to clean any parts if you are not instructed to do so in this manual. In particular,
do not clean the optical components inside the device from the light-emitting hole. Doing so may
affect the accuracy and performance of this product.
• When cleaning this product, do not use organic solvent (such as alcohol, ether, or thinner) on
coated parts, plastic parts, or printed parts. Use of such solvents may cause discoloration or
removal of printed characters.
• Note that the medicinal alcohol used for decontamination is highly flammable. Care must be
taken when operating the power switch in the presence of such chemicals, and pay special
attention to any potential fire hazards.
• Handle medicinal alcohol according to the precautions provided by the manufacturer.
• If organic solvent such as medicinal alcohol is used, make sure to wear fingerstalls or gloves to
avoid touching the solvent with bare skin.
