er and lift the top half of the container. Take care to ensure that the optical items (objectives and eyepieces)

do not fall out and get damaged. Using both hands (one around the neck and one around the base), lift the

microscope from the container and put it on a stable desk.

Place the observation head onto the top of the neck and tighten the lock-screw. Insert the eyepieces into the

eye tubes.

Connect the provided power supply to the power supply input jack on the rear of the microscope.

Intended use

For research and teaching and teaching use only. Not intended for any animal or human therapeutic or diag-

nostic use.

Operation

Adjust the observation head

Loosen the lock-screw, turn the observation head to a comfortable position for observation, and then lock the

lock-screw.

Place the specimen on the stage

Lock the specimen slide on the mechanical stage using the slide holder. Ensure that the specimen is centred

over the stage opening by adjusting the coaxial knobs of the stage.

Lamp settings

The microscope is tted with a power white LED illuminator. Before turning on the light, read the section

about electrical safety precautions. Insert the plug of the power supply into the jack on the rear and turn on

the ON/OFF switch. Turn the brightness adjustment knob to a brightness suitable for observation.

Adjust interpupillary distance (binocular models)

Hold the right and left side of the observation head with both hands and adjust the interpupillary distance by

turning the two parts until one circle of light can be seen, when looking down the microscope with both eyes.

Focus and diopter adjustment (binocular models)

Rotate the coarse focusing knob to bring the slide into focus using a low magnication objective. Adjust the

ne focusing knob to get the image sharp and clear while observing with your stronger eye, then turn the di-

optric adjustment ring on the opposite eyepiece until a sharp and clear image can be observed also with the

other eye. Turn the tension adjust knob to achieve a suitable focus tension without the specimen dropping out

of focus. When the image is in focus, turn the nosepiece to choose the objective you need.

Condenser adjustment

Hold the notched ring at the base of the condenser and rotate it up or down until you reach a clear and uni-

form sample illumination.

Set the numerical aperture

Adjust the aperture of the iris diaphragm to set the numerical aperture of the illuminator, thus controlling im-

age contrast and resolution.

HOLD THIS LEVER AND

ROTATE IT

Rechargeable battery (ML124 R and BL124 R models)

ML124 R and BL124 R models are equipped with a built-in rechargeable battery.

The battery can be recharged simply by connecting the microscope to the provided external power supply,

using the jack connector on the rear.

During the charging process, you can use the microscope as usual.

NOTE

In order to speed up the charging of the battery, it’s suggested to turn the LED off when you connect

the external power supply.

NOTE

For a full charge, it’s suggested to keep the external power supply connected to the microscope for at

least 8 hours.

WARNING

Always unplug the external power supply from the microscope, when not in use.

Automatic Light Control (ML124 ALC and BL124 ALC models)

ML124 ALC and BL124 ALC models have a special function called “Automatic Light Control”.

The level of light is adjusted by the microscope in order to maintain the same level as the one the user has

chosen, no matter if the aperture of the diaphragm changes, another objective is inserted, opacity of the

sample changes, etc.

1) Set the focus on the sample as described in the previous chapters, using the objective of your choice.

2) Rotate the brightness adjustment knob in order to get a comfortable level of illumination.

3) Press the ALC button on the side of the microscope.

Now the ALC system is working: if you open or close the aperture diaphragm or change objective, the system

will try to maintain the same level of illumination as the one you stored when you pressed the button.

4) Press the ALC button again to return to a manual control of illumination.

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 dehumidier 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.
