flange with the coupling ring (35.2).
Align the macro adapter (35.5) against the
macrodual zoom and secure with the threaded
ring (35.6).
Fasten the macro adapter and the macrodual

Changing the halogen lamp in the illumination
Disconnect from power supply.
Screw out the Allen screw at the back and
remove the lamp unit from the lamphousing.
Take the lamp out of the socket and replace,
making sure that the contact paths of the lamp
lie on the contacts in the socket.
Do not touch the lamp bulb with your fingers due
to the danger of perspiration burning in.
After the lamp unit has been replaced in the
lamphousing, the lamp holder can be adjusted
vertically by about 2 mm with the Allen screw
from beneath.
Looking through the microscope eyepiece,
adjust the lamp to the height where the greatest
image brightness is achieved.
