Welcome to the microworld!
With Levenhuk LabZZ MTB3 Microscope you will make lots of interesting discoveries and create exciting memories! Remember
that following safety rules is absolutely necessary. In the kit you will find the microscope, as well as many useful accessories.
Everything in place? Check it together with your parents.
How to work with the microscope
1. Check the microscope scheme thoroughly
2. Install batteries for illumination. Flip the microscope over and remove the cap from the battery compartment. Insert two AA
batteries (those are not the thinnest penlight batteries, but those that are a bit thicker). Insert the batteries according to
their polarity — make sure that the "+" sign on the battery matches "+" in the compartment (same goes for "-" signs)
Put the cap back on. Don't hesitate to ask adults for help if you are not sure.
3. Place the microscope on the flat surface near the source of bright light (window or a lamp). Turn the mirror towards the
illumination source. You should see a bright light spot through the eyepiece. If illumination in your room is not enough, switch
on the built-in illumination by turning over the mirror
CAUTION! Never direct the mirror towards the Sun, as it may ruin your eyesight and even cause blindness.
4. Now the microscope is ready for work.
5. Take a prepared microscope slide, place it on the stage and secure with holders.
6. Choose the objective by rotating the revolving nosepiece. The microscope comes with three objectives having different
magnifications (15x, 45x and 90x). Using these objectives with a 10x eyepiece, you can get 150x, 450x and 900x magnifications.
The longer the objective, the higher magnification it produces. Most observations are better performed with lower
magnification, so choose the shortest objective to start. You will hear a "click" when the objective is in place.
7. Slowly rotate the focusing knob so the objective is almost touching the slide. BUT! It shouldn't actually touch the slide as both
the slide and the objective may be damaged if it does. That's why you need to do everything very slowly and carefully. When
the objective is very close to the slide (but doesn't touch it!), look through the eyepiece and start to rotate the focusing knob
in the opposite direction very slowly until you see a clear image.
The microscope kit includes:
microscope, 10x eyepiece, spare bulb, empty flask (3 pcs), slides and cover slips (3 pcs each), slide stickers (3 pcs), plastic tools
(scalpel, pipette, spatula, forceps, dissecting needle).
Wonderful telescope
How to work with the telescope
It is very important to assemble the telescope correctly so it works the right way
the names of its parts, where each part goes and what it's needed for
1. Open the box and put out all the parts. Double-check the box when it's empty
2. Spread the tripod legs and install it on a flat surface so it is stable. The tripod height is adjustable.
3. Find the mounting screw on the telescope (located underneath). Loosen it and set the telescope on the mount. Insert the
screw in the holes on the telescope and the mount. Carefully tighten it. Attention: Do not overtighten the screw as you may
accidentally damage the screw thread.
4. Loosen the finderscope mounting screws and slide it in the finderscope base. Carefully tighten the screws. The finderscope
should be installed in a way so it points in the same direction as the telescope tube.
5. In the box with your telescope you will find two eyepieces. The lower the number on the eyepiece, the higher the magnification.
It's better to start observing using an eyepiece with low magnification and wide field of view.

helpful for terrestrial observations.
How to start observing
CAUTION! Never look at the Sun and the sky around it through a telescope! It can ruin eyesight and even cause blindness!
Before you start exploring the Cosmos, you should learn to operate the telescope during the day. Use the 18mm erecting eyepiece to
observe different terrestrial objects — houses, trees, antennas on the rooftops and many others! This way you will learn to control
the telescope and focus on desired objects. Besides, it's a lot of fun!
Attention: The telescope should be used in a place protected from the wind.
When you get to observing the Moon, planets and stars at night, remember to choose locations away from street lamps, car lights and
window lights. Try to observe on nights when the stars shine bright and evenly.
Point the telescope at the desired object, for example, the Moon. Looking through the finderscope, slowly move the tube until the
object is in the center. Now look through the eyepiece and you will see the image of the object magnified many times!
When working with the telescope, be careful and patient. Don't push it and don't move it from its place. After some training you will
learn to move the telescope tube without losing the object from the sight of the eyepiece.
The telescope kit includes:
telescope, 5mm and 10mm eyepieces, 2x optical finder, diagonal mirror, 650—1150mm aluminum tripod.
