CONTRAST.
Repair and maintenance
Microscopy environment
This microscope is recommended for use in a clean, dry and shock free environment with a temperature of
0-40°C and a maximum relative humidity of 85 % (non condensing). Use a dehumidifier if needed.
After using the microscope
The microscope should always be kept vertical when moving it 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 down the illumination intensity control and turn the light off. Cover the microscope with included
the 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 require cleaning first use compressed air.
If that is not sufficient use a soft lint-free cloth with water and a mild detergent.
And as a final option use the piece of cloth moistened with a 3:7 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 op-
tics. Do not disassemble objectives or eyepieces in an attempt to clean them.
For the best results, use the VWR cleaning kit (see catalogue number below).
If you need to send the microscope to manufacturer for maintenance, please use the packaging if possible.

CAUSE
Power supply not connected Check that the power supply is well
Connected
The iris diaphragm aperture
is not completely opened
Brightness level is low
Objective is not aligned with
the optical axis
Objectives or filters are dirty
Condenser at wrong height
8
SOLUTION
inserted on the rear of the microscope
Rotate the brightness adjustment
control and check if there is an
increase in the light output
Completely open the iris diaphragm
aperture
Rotate the brightness adjustment
potentiometer
Rotate the nosepiece until an objective
is well inserted in the optical path (it
"clicks")
Wipe them clean
Hold the condenser and rotate it until
you see a uniform illumination
