6. Changing the Lamp (Fig. 7)
1. Turn off and unplug the microscope.
2. Loose the screws (9) and remove the cover (8).
3. The halogen lamp (7) can be removed by grasping the bulb
and pulling it firmly from its socket (10). Take care not to
touch the lamp with bare fingers, as the lamp will be hot.
4. Insert a new halogen lamp into the same socket. When you
are installing the new lamp, be careful not to touch the glass
with your fingers. The new lamp should be supplied in a
plastic protective envelope. If not, use a tissue or another
medium to grasp the bulb. This will prevent contamination
from your hand from reducing the lamp‘s intensity and
lifetime.
5. Reinstall the cover to the frame.
6. If necessary, you may need to readjust the lamp as
previously described.

V. MAINTENANCE
1. Cleaning the frame and the stage
Disconnect the plug from mains socket before cleaning.
Clean the frame and the stage with a soft cloth moistened
with a mild detergent solution. Be sure that the instrument
is dry before using.
2. Cleaning optical parts
The eyepieces and the objectives of the microscope are
coated. They should not be wiped because dry dirt or dust
may scratch the coating. It is best to remove the parts to be
cleaned from the frame prior to cleaning. Always blow loose
dust away first. Use lens tissue of good quality moistened
with a lens cleaner or a small amount of alcohol; then wipe
the surface clean with a lens tissue. Solvents such as xyle-
ne should NOT be used as cleaner.
3.
Do not disassemble objective lenses!
