2 Assembly
− Remove the microscope from its box and packaging, carefully place it on a
stable work bench.
− Remove the plastic bags and the dust covers from the adaptors.
− Place the monocular head in the tube adaptor; tighten the knurled screw
with fingers.
− Familiarise your self with the mechanics of your microscope. Gently handle
each element to see how it behaves and what effect it has. Connect the
power cord correctly using the power supply provided with the microscope.
Note:
1) The microscope must have an earth connection.
2) Make sure that the supply voltage is adequate for the nominal voltage
of the microscope.
The batteries have an initial charge time of 5 to 6 hours. The standard charge
time is of 4 hours for an autonomy of 4 hours.

3 Use and adjustment

− To move the microscope, hold it by the inclined portion of the stand only,
placing the other hand underneath.
− Turn on using the switch at the back of the base, turn the light dimmer
switch on the right of the base to obtain the desired illumination.
− Place the sample (slide) to be examined delicately on the stage, cover slip
towards the objective lens. Delicately pinch the sample (slide) using the
slide holder.
− The 360° pivoting observation head and the 45° inclined tube provide an
excellent ergonomy and allow prolonged use.
− A light condenser is found under the stage. The intensity of the incident light
may be modified when the diaphragm aperture is adjusted.
