Installing batteries
The battery compartment (17) is located at the bottom of
the microscope. Loosen the locking screw of the battery
compartment cover first with a screwdriver. Remove the
cover. Insert three “AA” batteries.
Make sure that the polarities of the batteries are in the correct position as marked on the inner side of the battery
compartment. Re-insert the battery compartment cover and tighten the locking screw, only hand-tight to avoid any
damage of the cover.
Electric illumination (11, 12)
The microscope is equipped with a battery-powered LED illumination. Therefore, the usage with a off-grid power
supply (e.g. outside) is possible.
This microscope features both transmitted light and incident light, so that both transparent specimens and non-
transparent specimens can be examined. If opaque specimens are being examined, the light from below goes through
the specimen, lens and eyepiece to the eye and is magnified enroute.
Some small water organisms, plant parts and animal components are transparent by nature, but many others require
pretreatment – that is, you need to make a thinnest possible slice of the object by hand cutting or using a microtome,
and then examine this sample.
On/Off switch and Incident/Transmitted light switch are combined in a rotary switch (14). To power on the device, turn
the rotary switch (14) to number “
I
” hearing the first “click”, transmitted light (12) on; number “
II
” the second “click”,
incident light (11) on; and number “
III
” the third “click”, both transmitted and incident light on.
How to select the right illumination regarding different objects? Transmitted light for transparent objects, incident light
for non-transparent objects; and combination of transmitted and incident light for semi-transparent objects.
NOTE!
Do not operate the microscope with maximum brightness over a longer time. This will reduce the LED lifetime.
Observation
You begin each observation with the lowest magnification (eyepiece WF10x and objective 4x). So, the object to be viewed
can easy be centered and properly focused. The higher the magnification the more light is required for good image
quality.
Turn the objective revolver (6) onto the smallest magnification (4x) and insert the WF 10x eyepiece.
Place a preparation right above the transmission aperture on the microscope stage and fix it with the clips.
Look through the eyepiece, you can see the magnified preparation.
WARNING:
• Examine devices and make sure the battery compartment is correctly secured, e.g. that the
screw or other mechanical fastener is tightened. Do not use if compartment is not secure.
• Dispose of used button batteries immediately and safely. Flat batteries can still be dangerous.
• Tell others about the risk associated with button batteries and how to keep their children safe.
