1. General/Location
Make sure you position your microscope on a stable, solid surface.
An electricity supply is required for observation with the electric illuminator.
Position your device so that it can be disconnected from the power supply at any
time. The wall you use socket should be located near the device and easily ac-
cessible, since the plug on the power cord serves as a disconnecting device for
the power supply. Always pull on the plug to separate the device from the power
supply. Never pull on the cord.
2. Electric LED lighting with dimmer
Before use, make sure the light switch (19) is set to 'off'.
The microscope has two light sources. Lighting can be of three types. Set the
switch (19) to 'II' to light the specimen from above (reflected light) or 'I' to light it
from below (transmitted light). Use setting 'III' to light the specimen simultaneously
by transmitted and reflected light. The transmitted light unit (9) is used for transpar-
ent specimens (those on glass slides). To view solid, non-transparent specimens,
use the reflected light unit (18). Use of both forms of lighting simultaneously is
only recommended for semitransparent specimens. This operating mode is not
recommended for transmitted light specimens on slides as it may cause reflection
on the slide.
To operate the supplied main power pack (12), first connect it to the microscope
and then to a power socket (220-230V). Use the switch (19) to select the desired
lighting mode and set the dimmer (16) to the desired brightness.
As your device has continuously controllable lighting (dimmer), optimal illumination
of the object to be viewed is guaranteed.
3. Colour filter disc
The colour filter (17) under the microscope table (7) aids in viewing very bright and
transparent objects. Just select the right colour for the specimen in question. The
