IMPORTANT
This system employs a UIS (Universal Infinity System) optical design, and should be used only with UIS micro-
scopes, eyepieces, objectives and condensers for the BX2 series. (Some of the modules designed for the BX
series are also usable. For details, please consult Olympus or the catalogues.) Less than optimum performance
may result if inappropriate accessories are used.
1Getting Ready
1. This manual pertains only to the arrow pointer. Before using this attachment together with the microscope and associated
options, make sure that you have carefully read and understood their manuals, and understand how the system should
be operated together.
2. This system has a field number of 22. When the arrow pointer is combined with a superwide-field observation tube, the
pointer cannot be moved around the entire range of the field of view. Also note that a ghost of pointer may be observed
in such a case.
3. If the eyepiece in use incorporates a micrometer, ghost may be observed with dark specimens.
4. Always use the power cord and AC adapter provided by Olympus. If no power cord is provided, please select the proper
power cord by referring to the section “PROPER SELECTION OF THE POWER SUPPLY CORD” at the end of this instruction
manual. If the proper power cord is not used, product safety and performance cannot be guaranteed.
5. To ensure safety, disconnect the power plug of the AC adapter from the power outlet after operation.
6. The AC adapter cord should be fixed with the provided stoppers at a position that does not come in the way of operation.
Take special care so that the cord does not contact the lamp housing.

2 Maintenance and Storage
1. To clean the lenses and other glass components, simply blow dirty away using a commercially available blower and wipe
gently using a piece of cleaning paper (or clean gauze).If a lens is stained with fingerprints or oil smudges, wipe it gauze
slightly moistened with commercially available absolute alcohol.
Since the absolute alcohol is highly flammable, it must be handled carefully. Be sure to keep it away from open
flames or potential sources of electrical sparks —— for example, electrical equipment that is being switched on or
off. Also remember to always use it only in a well-ventilated room.
2. With any part of the arrow pointer other than glass components gets dirty, do not use organic solvents. If a plastic part gets
dirty, use a cloth moistened with a diluted neutral detergent.
3. Do not disassemble any part of the arrow pointer. This could result in malfunctions or reduced performance.
4. When the arrow pointer is not used, make sure to put the dust cover on it.

5. When the arrow pointer is used with the BX40, BX41, BX43, BX45, BX46, BX50, BX51, BX52, BX53, BX60 microscope frame,
only one intermediate attachment can be mounted in a 2-level configuration.
However, the usable intermediate attachment is restricted depending on whether it is mounted above or below the arrow
pointer.
· The only intermediate attachments that can be used on top of the arrow pointer is the U-EPA or U-EPA2 eyepoint adjuster.
For the intermediate attachments that can be used below the arrow pointer, consult the following sketch and select the
optimum one.

OPERATION
2-1 Focus Adjustment of the Arrow Pointer (Figs 1 & 2)
}For use in focusing of the pointer, one of the eyepiece sleeves should be
equipped with a helicoid (or a focusing mask).
1. Turn the pointer brightness control @ of the arrow pointer clockwise to
turn on the pointer ( ).
}Set the pointer color switching lever ² to other position than the middle
position. If the pointer cannot be seen in the field of view, move the pointer
at the center of field using the pointer control lever ³.
2. Looking into the eyepiece sleeve without the diopter adjustment ring, turn
the helicoid | of the eyepiece to focus on the pointer.
3. Looking into the eyepiece sleeve with the diopter adjustment ring, turn the
diopter adjustment ring ƒ to focus on the pointer.
4. Turn the coarse and fine focus adjustment knobs of the microscope to
focus on the specimen.

2-2 Pointer Operation
}Light intensity alignment range of the pointer has been set to comply with
a dark specimen, such as the case of fluorescence observation. For this
reason, in case of brightfield observation with high light illumination, you
may feel it difficult to identify the pointer even by rotating the pointer bright-
ness control dial which is not defect of this product.
1. While looking into the eyepiece, turn the pointer brightness control @
clockwise to vary the brightness continuously.
2. Turning the control to the fully counterclockwise position switches it off.
Using the pointer color switching lever ² select a color which is clearly
distinguishable from the specimen color.
· Top position: Red
· Middle position: Light shielded.
· Down position: Green

2-3 Notes on Photomicrography
In general, the procedure for taking photographs is the same as usual. This section describes special considerations that
apply when taking photographs with the arrow pointer installed.
1. Using the trinocular observation tube on top of the microscope, you can take photographs that include the pointer.
# When you use genuine Olympus trinocular observation tubes, photo eyepiece and photomicrographic equip-
ment, the pointer ( ) is always focused on the film plane.
2. Brightness of the pointer is set to be brighter than the specimen to ensure adequate contrast. This has the following
effects on photographs that are not apparent during visual observation.
· Since the pointer is always overexposed when exposure is correct for specimen, the pointer color will bleach to white in
color photographs.
· When taking photographs with photomicrographic equipment with automatic exposure control, the brightness of the
pointer will cause the specimen to be underexposed. In such cases, set the photomicrographic equipment’s specimen
distribution compensation dial to the OVER position.
· Since the effect of the pointer is especially great when making long exposures of dark specimens, check the exposure
time with the pointer illumination turned off, then make the exposure manually after turning the pointer illumination back
on.

ASSEMBLY
1. Remove the observation tube from the microscope frame in use @, and
attach the arrow pointer ² so that the pointer control lever is located on
the front.
2. Attach the observation tune removed before above the arrow pointer.
2Connecting the AC Adapter (Fig. 6)
Before connecting the AC adapter, turn the pointer brightness con-
trol fully counterclockwise to the OFF position.
The power cord is vulnerable when bent or twisted. Never subject it
to excessive force.
Always use the power cord and AC adapter provided by Olympus. IF
no power cord is provided with the microscope, please select the
proper power cord by referring to section “PROPER SELECTION OF
THE POWER SUPPLY CORD” at the end of this instruction manual.
1. Firmly connect the AC adapter’s output plug @ to the AC adapter input
connector ² on the left side panel of the arrow pointer.
2. Connect the power cord’s connector | into the AC adapter’s input con-
nector ³, then connect the power cord’s plug ƒ to the wall power outlet.
The power cord should be connected to a grounded, 3-conductor
power outlet. If the power outlet is not grounded properly, Olympus
can no longer warrant the electrical safety performance of the equip-
ment.
