BIOLOGICAL MICROSCOPE

IMPORTANT
Safety Symbols
The following symbols are found on the microscope. Study the meaning of the symbols, and always use the
microscope in the safest possible manner.
1. Make sur that the voltage selector switch @ located on the underside
of the base of the microscope frame is set to conform with the local
‘mains voltage. Move the switch using an Allen wrench, etc. (Fig. 1)
© When shipped from the factory, the switch is set to 110-120V and
230-240V in 100V and 2009 areas, respectively.
2. To avoid potential shock hazard and fire, always switch the main switch
© to "O" (OFF) and disconnect the power cord from the wall outlet
before replacing the bulb. Allow the lamp housing cover @and the bull
to cool before touching,
3. Install the microscope on a level table. The air vents on the underside of
the base should never be blocked such as by placing the microscope on
a flexible surface, e.g., a carpet, etc, as this could result in overheating
and cause a fire,
4. 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” ar the end of
this instruction manual. If the proper power cord is not used, Olympus
can no longer warrant the electrical safety and performance of the
equipment
5. Connect the power cord correctly and ensure that the ground terminal
of the power supply and that of the wall outlet are properly connected
H the equipment is not grounded, Olympus can no longer warrant the
electrical safety and performance of the equipment.
6. Never insert metal objects, etc. into the air vents of the microscope
frame
as
this
will
result
in
electrical
shock
and/or
personal
injury.

€ 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 operating environment conditions, refer to and adhere to
the conditions specified in Section 6, SPECIFICATIONS on
page 16)
3. The tension ofthe coarse focus adjustment knob should only
be adjusted by means of the tension adjustment ring,
4. Heat from this microscope is lod away by natural convection,
Consequenti, do not use itina constricted space and ensure
that the room is well ventilated,
5. When moving the microscope, carry it with one hand under
the base D and the other hand holding at the recessed handle
‘on the rear of the arm @ as shown in the illustration on the
left. Handle the microscope with care when moving it
* When moving the microscope, never hold the stage or
binocular section of the observation tube, etc. Also
make sure that eyepieces, specimen, etc. do not falloff.
*
Sliding
the
microscope
on the
surface
of
the
table
may
Faz damage or tear off the rubber feet and/or scratch the
table top surface.
Maintenance
and
Storage
1. Clean all glass components by wiping gently with gauze. To remove fingerprints or oil smudges, wipe with gauze
slightly moistened with a mixture of ether (70%) and alcohol (80%)
* Do not use a mixture of ether (70%) and alcohol (30%) to clean the lower lens (made of optical plastic) of
the eyepiece (NCWHK10X) because such solvents cloud the lens. If dust adheres to the lens, blow it off
or wipe it away gently with a dry cloth.
‘Since solvents such as ether and alcohol are highly flammable, they must be handled carefully. Be sure
to keep these chemicals 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 these chemicals
only in @ well-ventilated room.
2. Do not attempt to use organic solvents to clean the non-optical components of the microscope. To clean these,
use a lint-free, soft cloth lightly moistened with a diluted neutral detergent.
2. Do not disassemble any part of the microscope as malfunction or damage may occur
4, When not using the microscope, keep it covered with the provided dust cover.
Warning Labels
Warning labels are affixed at parts where special precaution is required when handling and using the microscope,
Always heed the warnings,
[Caution for
Warning Label Position | Base Underside "gay po car
If warning labels become soiled, peel off, etc. contact your local Olympus representative to have them replaced.

I the microscope is operated 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 operate the equipment as outlined in this instruction manual

The diagram below shows how to assemble the various components, The numbers indicate the order of assembly.
‘# When assembling the microscope, make sure that all parts are free of dust and dirt, and avoid scratching
any parts or touching glass surfaces.
+ Retain the provided Allen wrench. It should be used when units are replaced or added.

Я Mounting the Bulb (Replacement) Fo.)
1. Tum the microscope frame on its side and pull the lamp housing knob
on the underside of the base to open the lamp housing cover.
2, Holding the halogen bulb @ contained in the polyethylene bag to avoid
leaving fingerprints on the bulb, fully insert the contact pins into the
bulb socket @. When properly seated, pul off the polyethylene bag,

À Always use the designated bulb. Use of improper bulb may
result in fire,
À Do not touch the bulb with bare hands. If fingerprints are
‘accidentally left on the bulb, wipe the bulb with a sof, lint-free
cloth moistened with alcohol. Using a contaminated bulb will
shorten the service life of the bulb.

Proc ns for Bulb Replacement
‘A Whenever you replace the bulb during use or right after use,
first move the main switch to “O" (OFF), disconnect the power
cord from the wall outlet, and allow the bulb and parts around
the bulb to cool before touching.
# If the bulb burns out during an observation and needs to be
replaced, remove eyapieces, specimen, and other objects likely
to fall off, before tilting the microscope framo to replace the
bulb.
