Your microscope is made up of the following parts (Fig. 1-4):

WF 10x Eyepiece
45° inclined monocular head
Objective
Illumination (LED)
Microscope stage (with object plate)
Stage clips
Focus knob
On/off switch
Battery compartment
Mounting screws

Location
Before you start, choose an ideal location for using your microscope. It is important that you have enough light available (window, desk lamp).

Simple Observation

Turn the focus knob (7) to the upper stop. Now, place an object on the stage (5), directly under the objective (1). When you take a look through the eyepiece, you can see the magnified object. At this point, you still might see a slightly fuzzy picture. Adjust the image sharpness by slowly turning the focus knob (7).
Rotatable object plate Test with which plate side (black or white) your object can be viewed best.

Illumination
For observation with the electronic light source (4) you need to insert 2 AA batteries 1.5 V, in the battery compartment (9) on the base of the microscope. The battery compartment is opened using a Phillips screwdriver. Insert the batteries with the correct polarity (+/- indication). Put the battery cover first into the small opening so that the lid fits perfectly. Now you can tighten the screw. You can not turn on the light (4) with the on/off switch (8) on the base of the microscope.
