How do I use my microscope?
Before you use your microscope, make sure that the
table, desk, or surface that you place it on is stable
and is not subject to vibration. If the microscope
needs to be moved, hold it by the arm and base
while carefully transferring it. Once the microscope
is in a suitable location and the batteries are
installed, check the light source to make sure that it
illuminates. Use a microfibre cleaning cloth to gently
wipe the lenses off. If the stage is dirty with dust
or oil, carefully clean it off. Make sure that you only
raise and lower the stage using the focus adjustment
knob.
How do I operate the illumination?
Locate the mirror/light on the base of the microscope. Flip the mirror/light to the
“on” position (with the light facing up) and the light will illuminate. This microscope is
equipped with an incandescent light that illuminates the specimen from below. The colour
filter wheel is located in the middle of the microscope stage. The filters help you when
you are observing very bright or clear specimens. Using these filters, you can choose
various brightness levels and colours. This helps you better recognize the components of
colourless or transparent objects (e.g. sea salt).
How do I adjust my microscope correctly?
Place the microscope in a suitable location as described above, and sit in a comfortable
viewing position. Always start each observation with the lowest magnification. Adjust
the distance of the microscope stage so that the stage is in the lowest position, farthest
away from the turret head. Turn the objective turret until it clicks into place at the lowest
magnification (Objective 15x / 300x). Note: Before you change the objective setting, always
make sure the microscope stage is farthest away from turret by rotating the focus knob.
Separating the stage and turret by rotating the focus knob will avoid causing damage to
the specimen slide or microscope. When starting an observation, always start with the
15x / 300x objective in the rotating head.

How do I observe the specimen?
Sitting in your location with adequate
illumination chosen from the colour filter wheel,
the following basic rules should be observed:
Start with a simple observation at the lowest
magnification. Position the object or specimen
in the middle of the stage under the stage clips,
centred over the lower light. Focus the image
by rotating the focus knob until a clear image
appears in the eyepiece.
Place the prepared slide directly under
the objective on the microscope stage, and
secure it with the stage clips. The prepared slide should be located directly over the lower
illumination. Look through the eyepiece, and carefully turn the focus knob until the image
appears clear and sharp. Now you can select a higher magnification by rotating to the
30x/600x objective turret. Higher levels of magnification can be achieved by turning the
objective turret to a higher setting (600x or 1200x). Following this procedure creates a
steady increase of magnification without overpowering the view of the object. The following
magnifications should be considered: 300x, 600x, then 1200x. Each time the magnification
changes (due to the objective change), the image sharpness must be readjusted with the
focus knob. When doing this, be careful because if you move the microscope stage too
quickly, the objective and the slide could come into contact and cause damage to the slide or
microscope.
For transparent objects (e.g. sea salt), light is projected by the lower light traveling from
below the stage, through the objective and eyepiece, and finally into your eye. This process
of light transmission is known as microscopy. Many micro-organisms found in water, plant
components, and the smallest animal parts are transparent in nature. Opaque specimens,
on the other hand, will need to be prepared for viewing. Opaque specimens can be made
transparent by a process of treatment and penetration with the correct materials (media),
or by slicing. You can read more about creating specimens in the following Microscope
Experiments booklet.

CLEANING TIPS
To ensure your microscope has a long service life, clean the lens (objective and eyepiece)
with only a soft, lint-free cloth, like a microfibre cloth. Do not press down too hard while
cleaning, as this might scratch the lens. Ask your parents to help if your microscope is really
dirty.
The cleaning cloth should be moistened with cleaning fluid and the lens wiped clean using
very little pressure. Make sure your microscope is always protected against dust and dirt.
After use, leave it in a warm room to dry off.
WARNINGS AND SAFETY
Read and follow the instructions, safety rules, and first aid information.
This microscope set is intended for children older than age 8. Children should only use
this device under adult supervision. Never leave a child unsupervised with this device.
Accessories in this experimental kit may have sharp edges and tips. Please store the device
and all of its accessories and aids out of the reach of young children when not being used due
to a risk of injury.
This device contains electronic components that are powered by batteries. Batteries should
be kept out of children’s reach. When inserting batteries, please ensure the polarity is
correct. Insert the batteries according to the displayed +/- information.
DANGER OF FIRES AND EXPLOSIONS!
Do not expose the device to high temperatures. Use only battery types recommended. Never
mix old and new batteries. Replace all batteries at the same time. Never mix alkaline,
standard carbon-zinc, and rechargeable nickel-cadmium batteries. Never short circuit the
device or batteries or throw either into a fire. Exposure to high temperatures or misuse of
the device can lead to short circuits, fires, or even explosions. Leaking or damaged batteries
can cause injury if they come into contact with the skin. If you need to handle such batteries,
please wear suitable safety gloves.
CHEMICALS
Any chemicals and liquids used in conjunction with the device should be kept out of reach of
children. Do not drink any of the chemicals contained in this set. Hands should be washed
thoroughly under running water after working with these chemicals. In case of accidental
contact with eyes or mouth, rinse the affected area with water. Seek medical treatment for
ailments arising from contact with the chemical substances, and take the chemicals with you
to the doctor.

RISK OF MATERIAL DAMAGE
Never take the device apart. Please consult our customer service department and send
the device in for repair if needed.
Do not subject the device to temperatures exceeding 60 °C (140 °F).
TIPS ON CLEANING
Remove batteries from device before cleaning.
MICROSCOPE CARE
Clean the exterior of the device with a dry cloth. To avoid causing damage to electrical
components, do not use cleaning fluids. Clean the lenses (objective and eyepiece) with
only a soft, lint-free cloth, like a microfibre cloth. Do not use excessive pressure—this
may scratch the lens. Protect the device from dust and moisture. Store the device in its
original packaging. Batteries should be removed from the device if it will not be used for

DISPOSAL
Keep packaging materials, like plastic bags and rubber bands, away from children, as
they pose a risk of suffocation.
Dispose of packaging materials as legally required. Consult the local authority on the
matter if necessary.
DISPOSAL
Dispose of the packaging materials properly,
according to their type, such as paper or card-
board. Contact your local waste disposal service
or environmental authority for information on the
