Introduction
This microscope employs the UIS2 (UIS) optical systems. If you use eyepiece, objective, observation tube or
condenser, etc. together with this microscope, be sure that they apply to the UIS2 (UIS) optical system series.
Using inappropriate units restricts the performance.
(There are units usable with the BX series. Contact Olympus or refer to the latest version of catalogs.)

CAUTION - Installation of the product -
Safety precautions
If the product is used in a manner not specified by this manual, the safety of the user may be imperiled. In addition, the
product may also be damaged. Always use the product according to this instruction manual.
The following symbols are used in this instruction manual.
CAUTION : Indicates a potentially hazardous situation which, if not avoided, may result in
minor or moderate injury.
NOTE
: Indicates a potentially hazardous situation which, if not avoided, may result in
damage to the product or other property.
TIP
: Indicates the useful knowledge or information for use.
Install the microscope on a sturdy, level table or bench.
If you install the microscope on an unstable table or a tilted table, the
microscope may drop and you may get injured.
Prevent the microscope from overturning.
The microscope becomes unstable if the height of the microscope
is increased by the accessories mounted on it. In this case, as this
microscope may be overturned, take the actions to prevent the
microscope from overturning.
Attach each unit at the appropriate angle.
· If you use the BXFM system in combination with the stand (U-ST),
attach the BXFM frame (BXFM-F) at within ±30 degrees with respect to
the column. Also, attach the reflected light illuminator for BF (U-KMAS)
so that the lamp housing comes to the right side when viewed from
the front.
· When using the BXFM system in combination with the large stand
(SZ-STL) and the illuminator holder for BXFM (BX3M-ILH), set the
attaching angle of the BXFM frame (BXFM-F) in the range where the
center position of the objective used for observation is placed inside
from the both edges of the large stand by 50mm.

Do not combine with the unit which makes the microscope
unstable.
· Be sure to observe the total weight limit of the units loaded onto the
illuminator holder as shown below.
Illuminator holder Total weight limit of the units
BX3M-ILH
· Without the assist spring for BXFM (BXFM-ILHSPU):
Upper limit: 7.5 kg, lower limit: unlimited
· With the assist spring for BXFM (BXFM-ILHSPU):
Upper limit: 11.5 kg, lower limit: 6.5 kg *
* If the total weight is lighter than 6.5 kg, accuracy
of the fine focusing knob of the BXFM frame can
not be assured.
BXFM-ILHS Upper limit: 7.5 kg, lower limit: unlimited
· Do not use the illuminator holder for BXFM (BX3M-ILH) with
combination of the stand (U-ST), because this makes the system
unstable.
· When using the illuminator holder for BXFM (BX3M-ILH) with
combination of the large stand (SZ-STL), the image may fluctuate or
blur irregularly when a 50X or higher-power objective is used.
It is recommended to fabricate an exclusive clamping tool to clamp
the BXFM frame (BXFM-F).
CAUTION - Carrying the microscope
Hold the BXFM frame and the stand.
When moving the microscope, hold the stand by the bottom with one
hand, and hold the BXFM frame with the other hand.
Holding the coarse/fine focusing knobs or lamp housing, etc., may
damage the microscope.
Remove the sample and the units.
When carrying the microscope, be sure to remove the sample and the
eyepieces to prevent them from dropping.
Also, remove units attached. If you carry the microscope attached with
units, the danger to drop the microscope will be increased due to the
heavier weight.
Do not slide on the top surface of the table.
Do not move the microscope by sliding on the top surface of the table.
The rubber legs may be damaged.

CAUTION - Electric safety -
Always use the power cord provided by Olympus.
If the proper AC adapter, the power cord and other cables are not used, the electric safety and the EMC (Electro-
Magnetic Compatibility) performance of the product cannot be assured. If no power cord is provided, please select the
proper power cord by referring to the section “Proper selection of the power cord” at the end of this instruction manual.
Always connect the ground terminal.
Connect the ground terminal of the power cord and that of the power outlet. If the product is not grounded, our
intended electric safety and EMC performance of the product can not be assured.
Do not use the product in close proximity to the sources of strong electromagnetic radiation.
Proper operation may be interfered. The electromagnetic environment should be evaluated prior to operation of the
product.
Remove the power cord in case of emergency.
In case of emergency, be sure to unplug the power cord from the power cord connector on the product or from the
wall power outlet.
Install the product at the location where you can reach the power cord connector or the wall power outlet at hand to
remove the power cord quickly.
CAUTION - Protection for electric shock -
Keep the power cord and cables sufficiently away from the lamp housing.
If the power cord and cables contact a hot area of the lamp housing, they could melt and cause electric shock.
Do not insert any tools or metal fragments in the air vents of the product.
Doing so could cause electric shock, ignition or failure of the product.
Do not touch the product with a wet hand.
In particular, if you touch the main switch of the power unit or the power cord with a wet hand, electric shock, ignition
or failure of the product may be caused.
