1 Spare Tungsten Bulb 220/230 Volt 20 Watt for M-06
1 Battery Recharger for M-06 LED
Intended use of the microscope
The M-06 microscopes are developed to be used in schools. They are the ideal choice for biological preparations. These
microscopes are equipped with achromatic objectives, eyepieces, condensers, rough and fine adjustment

Directions for use

a) Preparations: Setting up the microscope
Take the microscope out of its Styrofoam wrapping and put it onto a stable and level working surface.
b) Work Instructions
Illumination
The model M-06 works with a tungsten bulb (220/230 Volt, 20 Watt) imbedded in the base. This bulb has an average opera-
ting time of 3000 working hours.
The model M-06 LED is equipped with LED lights. The electricity for the lighting is stored in rechargeable batteries. The light
of the LED bulbs hardly heats liquid specimens. This bulb has an average operating time of 100 000 working hours. The
lighting is switched on at the back of the base. The rechargeable batteries are best recharged overnight.
Power supply
The model M-06 LED can be connected to a normal power socket or used cable-free with the rechargeable batteries. One
battery charge lasts for about 10 operating hours. The included recharger can only be connected to a power circuit of 220
Volt. The recharger is protected against overcharging. First connect the recharger to the microscope, and then connect it to
the power circuit. Should the rechargeable batteries totally be discharged, please recharge them overnight. The batteries can
only be recharged when the microscope is switched off. Should the batteries be defective and need to be exchanged, please
contact place of purchase.
The model M-06 only operates with a power network of 220 Volt.
Placing the microscope slide
Place the microscope slide provided with an object sample onto the object stage, and fasten it carefully with the help of the
mobile spring clips. By turning the y/y object stage adjustment knobs (at the left under the object stage), you can move the
object to be viewed into the centre of the object stage. Please note that these knobs have two functions: They move the
microscope slide on the object stage forwards and backwards, or from the right to the left.
Adjusting the image sharpness
Start by viewing your object with a four times magnification. Turn the knob for coarse adjusting until you receive a clear pic-
ture. Then use the knob for fine adjusting to achieve an optimal sharpness. Proceed the same way with every other object.
Pay attention that the object does not touch the objective lens.
Brightness control
There are several ways of adjusting the illumination projected onto the object. Light influences the viewing quality especially
with high magnification. To regulate the illumination LED through the condenser, the blind can be opened or shut. To move
the light beam closer to or farther from the object, the condenser part can be turned up or down with the regulating knob. You
can also adjust the illumination with the dimmer. Adjust the dimmer to its lowest intensity, switch on the current, and increase
the illumination up to the wanted intensity.
Use these different possibilities of light adjustment in order to reach a perfect top view of your object.
