Do not subject the microscope to direct sunlight, high temperature and humidity, dust, or excessive vibration.
The operating conditions are: Ambient temperature:
10°C - 35OC (50°F - 95°F)
Relative humidity: 15% - 85%
3.
Prevent dust from accumulating on the lenses and avoid leaving fingerprints on the optics.
4.
Unplug the power cord before replacing the light bulb or fuse.
5. Connect the grounding wire of the microscope.
6.
Use the tension adjustment ring to adjust the rotational tension of the coarse focus adjustment knobs.

This microscope incorporates a noise filter in the electric circuit
built-in the microscope base, bleeding a very low voltage current
in order to reduce effect of any external noises. Therefore, if the
conductive part of the stand is touched without grounding, an electric
shock may sometimes be felt depending upon the humidity
