Under no circumstances should you touch the integrated halogen bulbs either during
operation or directly after use. These bulbs produce significant heat and therefore
there is a risk that the user could be severely burnt. So before handling the bulbs,
you must check that they have cooled down.
The microscope housing, on the other hand, is constructed so that no significant heat
radiation emanates from the device and that there is absolutely no risk of the user
burning themselves from the housing outer surfaces.
1.3 Storage
You should ensure that the device is not exposed to direct sunlight, temperatures
which are too high or too low, vibrations, dust or a high level of humidity.
The ideal temperature range is between 0 and 40°C and a relative humidity of 85%
should not be exceeded.
The device should always be located on a rigid, smooth, horizontal surface.
When the microscope is not being used, you should cover it with the enclosed dust
protective cover. When doing this, the power supply is stopped by switching off at the
main switch and unplugging the mains cable. If the eyepieces are being stored
separately, the protective caps must be fitted to the tube connectors. In most cases,
if dust and dirt gets inside the optical unit of a microscope this can cause irreversible
errors or damage.
The best way to store accessories which consist of optical elements, such as, for
example, eyepieces and objectives, is in a dry box with desiccant.
