Once positioned and installed with the necessary components, the microscope is ready to be used.
Your microscope is a laboratory instrument designed to last. Handle it always carefully and avoid
abrupt vibrations or shocks.
Always disconnect the power cable from the microscope when not in use for long time, while you
clean it or when you perform any maintenance.
AVOID DISASSEMBLING THE INSTRUMENT
Do not disassemble the instrument. This entails the cancellation of the warranty and may cause mal

function.
4.1 Observation head
Loosen the lock-screw (1), turn the observation head to a comfortable position for observation, and
then lock the lock-screw.
4.2
Place the specimen on the stage
Lock the specimen slide on the mechanical stage using the slide clamp. Ensure that the specimen is
centred over the stage opening by adjusting the coaxial knobs of the stage.
4.3 Illumination system settings
The microscope is fitted with a white LED illuminator. Before turning on the illumination system, read
the section 5.3 about electrical safety precautions. Insert the plug of the cable into the power socket
and turn on the switch on the
side of the main body. Turn the brightness adjustment knob to a bright-
ness suitable for observation.
4.4 Adjust interpupillary distance
Hold the right and left parts of the observation head with both hands and adjust the interpupillary dis
-
tance by turning the two parts until one circle of light can be seen.
The white dot (°) placed on th
e left e
yepiece shows the set interpupillary distance. Just remember this
value to help on later settings.
4.5 Focus tension adjustment
The tension of the coarse focusing knob is preset by factory. To change the tension according to your
preference, just rotate the knob (5) clockwise in order to increase it.
Excessive tension could damage the mechanism of focus. A too loosed tension causes the descent of
the stage by gravity or a sudden loss of focus. In this case, rotate the knob (5) to increase the tension.
