Safety Precautions
7. Ultraviolet light
WARNING
A mercury lamp radiates ultraviolet light that is harmful to the eyes and skin when the lamp is turned on. Direct
viewing of light from the lamp may result in snow blindness at a light case or blindness at the worst case. To
prevent injury, follow the guidelines below:
• Use a filter or a collector lens with UV cut specification in the optical path of the microscope or the
illuminator unless UV excitation light is necessary for epi-fl microscopy.
• When performing the epi-fl microscopy by using the UV excitation light, attach the filter cube dedicated to
the UV excitation light. And then, if you must see the objective or its surroundings, be sure to see through
the ultraviolet light shield.
8. For safety
While the mercury lamp is lit, it emits the very strong light beam, which includes ultraviolet light and is harmful to
human eyes and skin, through the light guide fiber connected to the product. The beam is so intense that there
are possibilities of danger, such as fire or burn, and especially, leading to blindness if one sees the beam directly.
In order to avoid an accident, the following instructions must be always observed:
• Attach the light guide fiber to the microscope before turning on the lamp.
While the mercury lamp is lit, it is strictly prohibited that removing the light guide fiber from the microscope
or looking into the light guide fiber tip.
• Before removing the light guide fiber from the product, turn off the lamp.
Also, before removing the light guide fiber from the microscope, turn off the lamp.
• Before turning on the power of the product, connect the light guide fiber correctly.
If the light guide fiber is not connected correctly and the power of the product is turned on, the connection
part of the light guide fiber becomes hot and it may cause a burn injury.

Safety Precautions
9. Mercury lamp (HG lamp) burst and gas leak
WARNING
If the lamp is scratched or used over the life, the lamp may burst or gas may leak from the lamp.
If the lamp bursts, the broken glass may be scattered and hurt human beings and/or the product. Besides, the
gas inside the lamp (vaporized mercury and Ar inert gas) is released into the air bringing about the danger of
inhaling the gas. To avoid these dangers and to cope effectively with these abnormal situations, please read
the articles below before using the product. For details about the lamp handling, refer to page 7, "3. When
handling mercury lamp" and follow the instructions.
• The inorganic mercury is said to be less harmful and less absorbed by human beings than the organic
mercury (methyl mercury), but sill is harmful and an utmost care is needed in handling them.
• If the lamp bursts or the gas leaks, all the personnel must immediately leave the room so as not to inhale
the mercury vapor. Further, thoroughly ventilate the room for at least 30 minutes.
• If you happen to inhale the mercury vapor, immediately rinse your mouth and throat with a plenty amount
of water. If mercury or mercury vapor contacts on your skin or gets into your eyes, wash it off with a plenty
amount of water likewise. If you feel sick, or notice any sign of illness, please at once consult your doctor.
• Before cleaning up the mess, wait till the lamp and the surrounding parts cool down.
• To gather the scattered liquid mercury, use a special material for absorbing the mercury (available from vendors
handling experimental materials). Dispose of them as the special industrial waste or dispose of them according
to the laws or rules of your local waste system.
• Pick up the broken pieces of glass with the greatest care so as not to cut your fingers. Put the broken
pieces of glass in a hard container and dispose of them as the special industrial waste or dispose of them
according to the laws or rules of your local waste system.
• Because safety is a top priority in the design of Nikon products, the hazards described above should not
pose any danger as long as you heed all of the warnings and cautions in the manuals and use the system
only for its intended purpose. However, the hazards described above could lead to an accident if you fail to
heed all of the warnings and cautions in the manuals, if you strike the system, or if you attempt to
disassemble the system. Therefore, always be sure to heed all of the warnings and cautions.
• If the lamp bursts, contact your nearest Nikon representative immediately. Never continue to use the
product in "as is" condition, because some glass shreds may remain in the product.

Safety Precautions
CAUTION
1. Do not wet the product or allow foreign matter to get inside
If the product gets wet, a short circuit may cause malfunction or abnormal heating of the product. Similarly, if
foreign matter gets inside, a short circuit may occur. If you accidentally spill water on the product, immediately
turn off the power switch (flip it to the "0" side) and unplug the power cord from the wall outlet. (Take care not
to touch the cord with wet hands at this time.) And then, wipe off the water with a dry cloth.
Check the connectors such as AC inlet on the back of the product. If you find any moisture, wipe them away.
If any liquid or foreign matter gets inside, do not use the equipment, but contact your nearest Nikon
representative.
2. Mercury lamp life expectancy
The average life expectancy of a Nikon HG lamp C-LHGFI is 2000
hours. Exceeding 2000 hours of use may lead to an accident such
as burst of the lamp. Always replace with a new lamp once the
RUN TIME counter reading exceeds "2000.0." (Hour meter reads
2000.0 which equals 2000 hours.)

Safety Precautions
3. When handling mercury lamp
CAUTION
When handling the mercury lamp, follow the guidelines given below and take enough care in order to avoid
accidents and injury caused by the lamp burst.
• Do not subject the lamp to shock or vibration.
• Do not allow dirt or fingerprints to get on the inner surface of the reflector.
• Do not scratch the inner surface of the reflector.
• Do not exert excessive force on the electrode or the reflector. (Particularly when installing the lamp into
the socket.)
• When attaching the lamp into the lamp holder, insert the lamp as far as it goes and fix the lamp with the
wire form hooked.
• When connecting the lamp cord, securely insert the connector.
• Take care not to cut your hands when cleaning up the glass shreds of the burst lamp.
• Do not use a lamp beyond its life expectancy.
• Store lamps in a proper storage environment. Storage of the lamp in an inappropriate environment may
cause the lamp to burst.
<Storage conditions>
Temperature: -20 to +60ºC
Humidity: relative humidity 90% maximum (no condensation)
Miscellaneous: Do not subject the lamp to vibration or shock as these may cause the lamp to burst or
shorten its life expectancy.
• Do not break the used up lamps, but dispose of them as the special industrial waste or dispose of them
according to the laws or rules of your local waste system.
<Supplemental notes>
• If fingerprints or dirt stuck on the reflector surface, wipe them with a piece of soft, clean cotton cloth or
gauze lightly dampened with absolute alcohol.
• The glass shards should be placed in a hard container for disposal.
• If you notice an abnormality while using a lamp, immediately stop operation and contact your nearest
Nikon representative.
• The product is designed to keep the glass shreds within the product even if the lamp bursts during
illumination (when a burst occurs inside the product).
• If the lamp bursts during illumination, wait till the periphery of the lamp cools sufficiently before cleaning
up.
• For details on installing a lamp, see page 14, "Installing/replacing the mercury lamp."
4. Ozone
It is assumed that a small amount of ozone is produced during mercury lamp illumination. Since ozone can
irritate the mucous membranes of the eyes and nose upon contact, be sure to provide sufficient ventilation
while the lamp is illuminated. Never inhale the air exhausted from the mercury lamp directly, or never let the
same air hit your face.
