in contact with skin, therefore use suitable protective gloves to handle corrupted rechargeable battery.
• Rechargeable battery must be kept out of reach of children. Do not leave rechargeable battery lying
around, as there is risk, that children or pets swallow them.
• Rechargeable battery must not be dismantled, short-circuited or thrown into fire. Never recharge non-
rechargeable battery. There is a risk of explosion!
• Do not charge the rechargeable battery via mains power supply while the microscope is connected to a
powered USB 2.0 port. This may cause the battery to overheat.
c) Adaptor
• The mains outlet must be located near to the device and be easily accessible.
• As power supply, only use the supplied mains adaptor.
• Only connect the power adaptor to a normal mains socket connected to the public supply. Before
plugging in the power adaptor, check whether the voltage stated on the power adaptor complies with the
voltage of your electricity supplier.
• Never connect or disconnect power adaptors if your hands are wet.
• Never unplug the power adaptor from the mains socket by pulling on the cable; always use the grips
on the plug.
• When setting up the product, make sure that the cable is not pinched, kinked or damaged by sharp
edges.
• Always lay the cables so that nobody can trip over or become entangled in them. This poses a risk of
injury.
• For safety reasons, disconnect the power adaptor from the mains socket during storms.
d) Microscope
• Do not examine objects with temperatures outside the given operating temperature range of the product.
• Sudden temperature change may form dew inside the Microscope like entering a warm room in cold
winter. Put it inside a handbag or plastic bag to slow down temperature changes.
• Do not point Microscope lens to the sun or strong light for a long time. Powerful light may damage the
light-sensitive electronics.
• Do not force the card into the slot as this may damage the microscope and the MicroSD memory card.
• The base of the microscope may leave marks on sensitive surfaces.
e) Protection Against Dust
• Dust and debris from the air can lead to deterioration of image quality. Keep the Microscope away from
dusty environments.
• The opening of the camera lens should always be protected either with dust covers such. Suitable
options include aluminium foil or plastic bags.
• If dark specks or similar in-focus artifacts are observed in digital images, and they are not in the specimen
plane, their most likely cause is particulate contamination on the image sensor or an associated filter
surface. The cameras always need to be handled with the utmost care and protected from dirt according
to the manufacturer's recommendations.
• Before every critical use, check the front lens of the objective for dirt.
