5.9 Changing the bulb
Halogen
Before changing the halogen bulb, you must always switch off the device and
unplug it from the mains . You must also make sure that the bulb and housing
have cooled down, so that you avoid any risk of possible burn injuries.
To change the bulb, the whole lamp housing, fitted underneath the working stage,
has to be removed. Therefore you have to tip the device carefully to the back or side
and then loosen the fixing screws (Allen wrench) at the bottom of the working stage.
When doing this, please make sure that all microscope components are firmly fixed.
The bulb which appears inside the open lamp housing can then be simply pulled out
of its socket and replaced with a new bulb. You must then position and fix again the
housing correctly.
Please always use cloth gloves or similar to hold and fit a new bulb otherwise
grease and dust residue on the surface of the bulb could have a negative effect
on its brightness and service life.
5.10 Changing the fuse
There is a fuse
on the rear of the microscope stand base (label: “Fuse”).
If the fuse has blown, then with the device switched off and the power disconnected,
the fuse can easily be unscrewed using a flat blade screw driver and replaced with a
new one.
