9 Changing the bulb
Halogen
You must not attempt to change the bulb immediately after the microscope has been
used, as the bulb will still be hot and so there is a risk that the user could be burnt.
Before changing the bulb the device must be switched off and unplugged. To change
the bulb, tip the device carefully to the back or side. When doing this, please make
sure that all microscope components are firmly fixed. The bulb holder is on the
underside of the device. It can be opened by undoing the screws on the holder (see
illustration). We recommend that here you should also test again, to check that heat is
no longer being produced. The defective bulb can be pulled out of the socket and be
replaced with a new one. After the bulb holder has been replaced in the underside of
the device and the screws replaced, the bulb replacement procedure is complete.
Important:
When fitting the new bulb into the socket, it must only be handled with sterile gloves
or using the bulb packaging film. Grease and dust residue can have a negative effect
on the light quality and service life.
LED
The OBN 135 is equipped with LEDs.
Due to the long service life of LED lighting, regular lamp replacement will not be
necessary with this microscope.
In most cases, problems with the lighting would therefore be caused by defects in the
electrical system. In such a case, our Technical Service can help.
10 Changing the fuse (OBN 132)
The fuse housing is located at the rear of the microscope below the mains plug
connection. When the device is switched off and the mains plug is removed, the
housing can be pulled out. It is advisable to use a screwdriver or similar tool to help
with this. The defective fuse can now be removed from its housing and replaced with
a new one.
