9. Disposal of the microscope
To avoid biohazard risk, dispose of the microscope as contaminated equipment according to the standard
procedure of your laboratory.

Notes on handling the microscope

1. Handle the microscope gently.
This product is a precision optical instrument. Handle it carefully, and do not subject it to strong shocks.
The precision of the objectives in particular can be adversely affected even by weak shocks.
2. Dirt on the lens.
The scratches and dirt such as fingerprints on the optical parts (such as lens and filters) will adversely affect the
microscope image. If these parts get dirty, clean them following the instructions described on "Care and
maintenance" at the end of this manual.
3. Dirt on the lamps.
Do not touch the lamp by bare hands. Dirt or fingerprints on the lamp will cause uneven illumination and shortens
the life of the lamp. When handling lamps, wear gloves.
4. Installation location.
Using or storing the microscope under unsuitable conditions may damage it or may have an adverse effect on its
accuracy. The following conditions should be kept in mind when selecting the installation location.
• Choose a flat surface with little vibration.
• Choose a location less exposed to hazards in the event of collisions, earthquakes, or other potential disasters. If
required to keep the device from falling, use strong rope or other means to secure the microscope to the working
desk or to another heavy, stable item.
• Avoid a brightly lit location such as a room that receives direct sunlight.
• Choose a location that is free from dust or dirt.
• Do not install the microscope in a warm (60°C or more), humid (85% or more) location. (Mold or condensation
will form on the lenses and filters.)
• Leave enough space against the nearby wall since the lamphouse will become hot by lamp illumination.
• When using the "T-DH dia-illuminator 100W", leave a certain space between the microscope and the nearby wall to
allow the user to look at the caution symbols on the dia-illuminator and the lamphouse. If you are planning to use
the tilting function of the "T-DH dia-illuminator 100W", even more space is needed for the illuminator to tilt
backward.
• The room light just above the microscope may come into the objective as an extraneous light. (Especially when
using a condenser lens with longer working distance such as SLWD, ELWD and LWD lenses.) To avoid this, we
recommend to turn off the room light above the microscope when observing the image.
5. Focusing knobs.
• Never turn the focus knobs on the left and right sides of the microscope in opposite directions at the same time,
as doing so can result in damage to the microscope.
• Turning the coarse focus knob as far as it will go and then attempting to turn it further will result in damage to the
microscope. Never use undue force to turn the knob.
(For TE2000-E only) The coarse focus knob turns in sync with motorized Escape/Refocus movements. To prevent
•
malfunctions, avoid contact with the coarse focus knob during motorized Escape/Refocus movements.
6. Protect the ports.
When not using any of the ports, be sure to attach the supplied cap to it. If not, extraneous light and dusts will enter
the microscope.
