•Switch on the microscope with the on/off
switch (32.1, 33.5).

yet. First, work in transmitted light in order to
familiarize yourself with the microscope’s
controls.

condenser centering.
The following procedure is provided for trans-
mitted light-bright field illumination.
• If present: click the condenser disk* into the
BF position.
• If present: pull the light ring slide* out of the
condenser.
