This microscope is recommended to be used in a clean, dry and shock free environment with a tem-
perature of 0-0°C and a maximum relative humidity of 85 % (non condensing). use a dehumidifier
if needed.
5.2 To think about when and after using the microscope
• The microscope should always be kept vertically when moving it and be careful so that no
moving parts, such as the eyepieces, fall out.
• never mishandle or impose unnecessary force on the microscope.
• never attempt to service the microscope yourself.
• After use, turn off the light immediately, cover the microscope with the included dust-cover,
and keep it in a dry and clean place.
5.3 Electrical safety precautions
• Before plugging in the power cord with the supply, make sure that the supplying voltage of
your region matches with the operation voltage of the equipment and that the lamp switch is
in off-position.
• do not turn the power on and off, off and on immediately as this will shorten the life span of
the bulb and may cause damage to the electrical system.
• users should observe all safety regulations of the region. The equipment has acquired the
CE safety label. however, users do have full responsibility to use this equipment safely.
5.4 Cleaning the optics
• If the optical parts need to be cleaned try first to: use compressed air.
• If that is not sufficient: use a soft lint-free piece of cloth with water and a mild detergent.
• And as a final option: use the piece of cloth moistened with a : mixture of ethanol and
ether.
note: ethanol and ether are highly flammable liquids. do not use them near a heat source,
near sparks or near electric equipment. use these chemicals in a well ventilated room.
• remember to never wipe the surface of any optical items with your hands. Fingerprints can
damage the optics.
• do not disassemble objectives or eyepieces in attempt to clean them.
