Fig. 1
This microscope employs a UIS2/UIS (Universal Infinity System) optical design, and should be used only with UIS2/UIS eyepieces, objectives and condensers for the BX2 series. (Some of the modules designed for the BX series and objectives/eyepieces for the UIS series are also usable. For details, please consult Olympus or the catalogue.) Less than optimum performance may result if inappropriate accessories are used.
1. After the equipment has been used in an observation of a specimen that is accompanied with a potential of infection, clean the parts coming in contact with the specimen to prevent infection.
· Moving this product is accompanied with the risk of dropping the
specimen. Be sure to remove the specimen before moving this product.
· In case the specimen is damaged by erroneous operation, promptly
take the infection prevention measures.
2. Install the microscope on a sturdy, level table or bench so as not to block the air vents on the underside of the base. Do not place the microscope on a flexible surface, as this could result in blocking the air vents and cause overheating or a fire.
3. To prevent obstruction of the natural convection-based air cooling of the microscope, make sure to leave at least 10 cm of free space between walls or other objects, and the left, right and rear sides of the microscope and the lamp socket when installing the microscope.
4. To avoid potential shock hazards and burns when replacing the light bulb, set the main switch @ to “
” (OFF) then disconnect the power cord from the wall outlet in advance. Whenever you replace the bulb during use or right after use, allow the lamp socket ² and bulb to cool before touching. (Figs. 1 & 2)
Designated bulb 6V30WHAL (PHILIPS 5761)
#The microscope also incorporate a fuse (this should be replaced by
the manufacturer or authorized agent).
5. Always use the power cord 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.
6. Always ensure that the grounding terminal of the microscope and that of the wall outlet are properly connected. If the equipment is not grounded/earthed, Olympus can no longer warrant the electrical safety and performance of the equipment.
7. Never insert metallic objects into the air vents of the microscope frame as this could result in electrical shock, personal injury and equipment damage.
8. The power cord may be melt by the heat of lamp socket if the cord comes in contact with it. Distribute the power cord at an enough dis­tance from the lamp socket.

1 Getting Ready
1. A microscope is a precision instrument. Handle it with care and avoid subjecting it to sudden or severe impact.
2. Do not use the microscope where it is subjected to direct sunlight, high temperature and humidity, dust or vibrations. (For the operating condi­tions, refer to section 5, “SPECIFICATIONS”.)
3. When moving the microscope, remove the specimen and modules that may drop during transport and carefully carry it with the grasping part on the rear of the arm and the base as shown in Fig. 3 (Weight: approx. 13 kg). Be sure to remove the specimen @ that is likely to drop and the filter ² on the filter mount.
#If an intermediate attachment hinders you grasp the grasping part
on the rear, remove the intermediate attachment before carrying.
#Damage to the microscope will occur if you grasp it by the stage,
coarse/fine adjustment knob or binocular section of the observa­tion tube.
4. The BX41 can be used with up to two intermediate attachments (e.g. a U­CA magnification changer, U-EPA2 eyepoint adjuster, etc.). For restrictions when using two intermediate attachments, make sure to read the in­struction manual provided with the respective intermediate attachments.
#The microscope becomes unstable particularly when the U-TRU
trinocular attachment is attached on the side position or the microscope height is increased. In this case, take measures for preventing the microscope from toppling down.

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. The filter mount lens on the base is made of plastic. Do not rub it with a strong force to prevent damaging it.
3. Do not attempt to use organic solvents to clean the microscope components other than the glass components. To clean them, use a lint-free, soft cloth slightly moistened with a diluted neutral detergent.
4. Do not disassemble any part of the microscope as this could result in malfunction or reduced performance.
5. When the microscope is not in use, be sure to set the main switch to “ ” (OFF). After checking that the lamp housing has been cooled down, place the dust-prevention cover on the microscope for storage.
6. When disposing of the microscope. Check the regulations and rules of your local government and be sure to observe them.
