Notes on Handling the Instrument
1 Handle the instrument with care
This product is a precision optical instrument. Always handle it with care and do not subject it to strong physical shock.
2 Lens cleaning
Do not let dust, fingerprints, etc. get on the lenses. Dirt on the lenses, mirrors, etc. will adversely affect the view of the
image. If any of the lenses gets dirty, clean it as described in Chapter 5 “Care and Maintenance.”
3 Installation location
The following conditions should be kept in mind when selecting the location for installation:
●Install the instrument on a surface with little vibration.
●Install the instrument in a location which is not exposed to direct sunlight.
●Install the instrument in a location which is free from dust.
●Do not install the instrument in a warm and humid location (where the temperature is above 40°C or the humidity is
above 60%).
In such a location, mold or condensation may form on the lenses or filters.
4 Use of accessories
This attachment splits the light to allow several observers to view the same image simultaneously. Due to the working
principles of the attachment, the brightness of the image is reduced as the number of observers is increased. The light
source produces sufficient light intensity to allow normal observation of an image with adequate brightness by
adjusting the ND filters inserted in the microscope main unit (main observer’s section).
However, depending on the accessories being used, adequate brightness may not always be obtained. Please consult
your dealer or nearest Nikon representative before using accessories.
5 Pointer and AC adapter
The AC adapter to be connected to the pointer should always be the one provided with the pointer. The use of any
other type of AC adapter could result in accidents or damage to the instruments.
6 Weak electromagnetic waves
This product emits weak electromagnetic waves. So as to avoid degrading the performance of precision electronic
devices, do not install this product near such devices. If TV or radio reception is affected, move the TV or radio farther
from this product.

If the system has not yet been assembled, see Chapter 3 “Assembly” first.
For details on assembling and handling the microscope, see the instruction manual supplied with the microscope.
Depending on the type of set you have purchased, some of the components described below may not be included.
1
Adjust the microscope correctly.
The secondary observer will view the same image as the main observer. If the main observer does not adjust the
microscope correctly, the secondary observer will not be able to view a correct image. Also when the main observer
did not perform the diopter adjustment, the secondary observer is likely to have his image out-focused each time the
main observer changes the objective magnification. Be sure to perform the diopter adjustment referring to the
instruction manual supplied with the microscope.
2
Adjust the diopter setting at the secondary observer's position as well.
After the main observer has adjusted the microscope correctly, the secondary observer should bring the image into
focus with the diopter adjustment rings. Set the diopter adjustment rings for both the left and right eyes.
3
Method for simple diopter adjustment
When a pointer is attached to the system, turn the respective diopter adjustment rings on the left and right eyepieces
to bring the arrow into focus. It is needed to change the arrow color to green, and to move the arrow to near the
center of view field in advance. This completes diopter adjustment.

Care and Maintenance
5
1 Lens and filter cleaning
Do not let dust, fingerprints, etc. get on the lenses and filters. Dirt on the lenses, filters, etc. will adversely affect the view of
the image. If any of the lenses or filters gets dirty, clean it as described below.
Use a blower, etc. to blow away dust. If this is not sufficient to remove the dust, brush away with a soft brush or gently
wipe away with gauze.
To remove fingerprints or grease, use a piece of soft, clean cotton cloth, lens tissue, or gauze moistened with absolute
alcohol (ethyl alcohol or methyl alcohol). However, do not wipe twice with the same part of the cloth.
Use petroleum benzine to clean off immersion oil. Wiping with absolute alcohol (ethyl alcohol or methyl alcohol) will
complete cleaning.
If petroleum benzine is not available, use methyl alcohol. Note that the cleaning effectiveness of methyl alcohol is low
and it will be necessary to repeatedly wipe. (Normally, wiping three or four times is sufficient.)
Be sure to use petroleum benzine only for cleaning off immersion oil from objectives. Do not use it for cleaning
eyepiece tube entrance lenses, filters, etc.
Absolute alcohol and petroleum benzine are both highly flammable. Be careful when handling them, when around open
flames, or when turning the power switches ON and OFF.
Follow the instructions provided by the manufacturer when using absolute alcohol and petroleum benzine.
2 Cleaning painted components
Do not use organic solvents such as alcohol, ether or paint thinner on painted components, plastic components or printed
components. Doing so could result in discoloration or in peeling of the printed characters. For persistent dirt, dampen a
piece of gauze with neutral detergent and wipe lightly.
3 Storage
Store the instrument in a dry place where mold is not likely to form.
Store the objectives, eyepieces, filter cubes, etc. in a desiccator or similar container with a drying agent.
Protect the instrument from dust by covering it with the vinyl cover.
Before putting on the vinyl cover, turn off the power switch on the microscope and other equipment, and wait until the
lamphouse has cooled.
4 Regular inspection
Regular inspection of this attachment is recommended to maintain optimum performance. Contact your dealer or nearest
Nikon representative for details about regular inspection.
