12. Maintenance

Microscopy environment
This microscope is recommended to be used in a clean, dry and shock free environment with a temperature of 5°-40°C and
a maximum relative humidity of 85 % (non condensing). Use a dehumidifier if needed.
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 provided dust cover, and keep
it in a dry and clean place.

Electrical safety precautions

• Before plugging in the power 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.
• 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.
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 7:3 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.
For the best results, use the OPTIKA cleaning kit (see catalogue).
If you need to send the microscope to Optika for maintenance, please use the original packaging.
