DISPOSAL

Dispose of the packaging materials properly, according to their type (paper, cardboard, etc). Contact your local waste disposal service or environmental authority for information on the proper disposal. Do not dispose of electronic devices in the household garbage! As per the Directive 2002/96/EC of the European Parliament on waste electrical and electronic equipment and its adaptation into German law, used electronic devices must be collected separately and recycled in an environmentally friendly manner. Empty old batteries must be disposed of at battery collection points by the consumer. You can find out more information about the disposal of devices or batteries produced after 01.06.2006 from your local waste disposal service or environmental authority. In accordance with the regulations concerning batteries and rechargeable batteries, disposing of them in normal household waste is explicitly forbidden. Please pay attention to the disposal of your used batteries as required by law – at a local collection point or in the retail market (disposal in domestic waste violates the Battery Directive). Batteries that contain toxins are marked with a sign and a chemical symbol. „Cd“ = cadmium, „Hg“ = mercury, „Pb“ = lead.

Object plate

Location
Before you start, choose an ideal location for using your microscope. It is important that you have enough light available (window, desk lamp).
Simple Observation
Place the object to be observed (for example, a rock) in the middle of the microscope stage (5). When the object is large enough, it is best to fix it in place with the stage clips (6). Now, take a look through the binocular eye lens (1) and change the distance of the eyepiece (3), so that you have a circular, clear image. The sharpness is adjusted by slowly turning the focus knob (7).
Illumination
Remove both eyepieces (3) from the eyepiece supports (1) and turn the entire microscope over. At the base of the microscope, there is a battery compartment (9). Loosen the fixing screw (10) of the battery compartment cover and remove the cover. Place the batteries in the compartment so that the flat minus poles (-) press against the spring terminal and the plus poles (+) are touching the flat contact sheets (11). Put on the cover and fix it with the screw (10). Turn the microscope over again. Place the eyepieces back on. You can not turn on the light (4) with the on/off switch (8) on the base of the microscope.

TIPS on cleaning

Remove the device from its energy source before cleaning (remove batteries). Clean the exterior of the device with a dry cloth. Do not use cleaning fluids so as to avoid causing damage to electronic components. Protect the device from dust and moisture. Store the device in the bag supplied or in its original packaging. Batteries should be removed from the device if it is not going to be used for a long period of time. Clean the lens (objective and eye- piece) only with a soft lint-free clean-ing cloth (e.g. microfibre). Do not use excessive pressure – this may scratch the lens. Dampen the cleaning cloth with a spectacle cleaning fluid and use it on very dirty lenses.
