IMPORTANT
The BXFMA-F motorized illuminator with motorized focusing unit can be installed in a user’s system in
combination with the BX-UCB control box as well as a PC (running the BX2-BSW software) or the
U-HSTR2, U-FH focus adjustment knob unit and U-IFFH focus adjustment knob interface.
The instructions for the BX/UCB/U-HSTR2 and software (BX2-BSW, commands) are provided in separate
instruction manuals. Please also refer to these manuals as required.

Precautions When Unpacking the Microscope
}To prevent deterioration in performance during transport, the illuminator is shipped with transport lock applied to the
focusing unit, observation method switch and aperture iris diaphragm (AS) mechanism, Be sure to release the transport
lock of these three modules before assembly, and engage the transport lock before the next transport of the illuminator.
Releasing the Transport Lock of the Observation Method (BF/DF)
Switch Mechanism (Fig. 1)
Turn the lock knob 1 counterclockwise to loosen it, and remove it together
with the caution tag.
}Retain the lock knob carefully because it will be used again the next time
the equipment is transported.
To set transport lock:
1. Switch the observation method to DF (reflected light darkfield).
2. Turn the lock knob all the way clockwise.

Releasing the Transport Lock of the Focusing Unit Mechanism (Fig. 2)
1. Turn the two lock knobs 2 counterclockwise to loosen and remove them.
2. Similarly to step 1, turn the two lock screws 3 to remove them.
}Retain the lock knobs and lock screws carefully because they will be
used again the next time the equipment is transported.
To set transport lock:
1. Raise the focusing unit to the higher limit position.
2. Turn the two lock screws all the way clockwise.
3. Similarly to step 2, turn and tighten the too lock knobs.

SAFETY PRECAUTIONS
Fig. 3
1. Keep your hands apart from the revolving nosepiece during focusing
operation and while the main switch of the BX-UCB control box is set to
“ I ” (ON). If your finger is caught by the up/down movement of the revolving
nosepiece, an injury such as bone fracture my result.
Should your finger be caught by the revolving nosepiece, lower it with the
following method:
· Set the main switch to “ ” (OFF), remove the right side panel of the
illuminator using a Phillips screwdriver and turn the manual knob 1 inside
the panel in the opposite direction to the direction shown in the figure (i.e.
clockwise) to lower the revolving nosepiece. (Fig. 3)
2. Emergency stop of focus operation is possible by turning the focus
adjustment knob on the microscope frame or on the U-FH (in either
direction), or by pressing the FOCUS control button ( , , F/C or ESC),
after focus operation has been activated (except when data is being
downloaded to a PC).
When the BX-UCB control box’s main switch is set to “ I ” (ON), the focus
operates automatically (the objective raises once and then returns to the
original position) for initialization. (It takes about 20 seconds.)
If the above emergency procedure is performed during this automatic
focus operation, the microscope stops operating. Should this happen,
set the main switch to “ ” (OFF) and then “ I ” (ON) again.
3. The surface of the lamp housing on the side of the illuminator becomes
very hot. When installing the system, leave spaces of more than 10 cm
around, particularly above the lamp housing.
4. Be careful not to touch the lamp housing when centering the aperture
iris diaphragm or controlling the field iris diaphragm. You run the risk of
burn if you touch the lamp housing while the lamp is lit or immediately
after it is turned off.
5. Route the connection cables away from the lamp housing. Should a
cable comes in contact with the hot lamp housing, the cable could melt
and cause electric shock.
6. When installing the illuminator in an existing system, insert 6 bolts in the
module installation screw holes and tighten firmly.

Safety Symbols
The following symbols are found on the motorized illumination system. Study the meaning of the symbols and always
use the equipment in the safest possible manner.
Symbol Explanation
Be careful not to have your finger or hand caught (between the revolving nosepiece and illuminator
or between the specimen and objective).
Indicates that the surface becomes hot, and should not be touched with bare hands.
Before use, carefully read the instruction manual. Improper use could result in personal injury to
the user and/or damage to the equipment.
Indicates that the main switch is ON.
Indicates that the main switch is OFF.

1 Getting Ready
1. The illuminator is a precision instrument incorporating motorized parts. Always install it horizontally (it is inhibited to install
it on the side panel), handle it with care and avoid subjecting it to sudden or severe impact.
2. Do not use the system where it is subjected to direct sunlight, high temperature and humidity, dust or vibrations. (For
operating conditions, see Chapter 6, “SPECIFICATIONS” on page 19).
3. Only one intermediate attachment can be used, by installing the U-AFA1M active AF unit, U-CA magnification changer or
U-EPA2 eye point adjuster above the motorized illuminator.
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. Do not attempt to use organic solvents to clean the non-optical components of the microscope system. To clean them,
use a lint-free, soft cloth slightly moistened with a diluted neutral detergent.
3. Never attempt to disassemble any part of the microscope system.
4. When not using the microscope, set the main switch to “
cover the microscope with a dust cover before storage.
5. When disposing of this product, check the regulations and rules of your local government and be sure to observe them.
” (OFF), wait until the lamp housing has cooled down, and
3 Caution
If the system is used in a manner not specified by this manual, the safety of the user may be imperiled. In addition, the
equipment may also be damaged. Always use the equipment as outlined in this instruction manual.
The following symbols are used to set off text in this instruction manual.
!: Indicates that failure to follow the instructions in the warning could result in bodily harm to the
user and/or damage to equipment (including objects in the vicinity of the equipment).
# : Indicates that failure to follow the instructions could result in damage to equipment.
} : Indicates commentary (for ease of operation and maintenance).
