Storage 

It is important that the microscope is covered with the enclosed protective cover after 
each use. In the long term, this is the only way to protect it from getting dirty. Ideally 
the microscope will be used in an air-conditioned room. If the microscope is not used 
for  several  days,  then  we  would  recommend  that  it  is  stored  in  a  cupboard  with  its 
protective cover. Dust and moisture are the greatest enemies of the microscope. 

 

Maintenance 

These  microscopes are  generally  maintenance-free.  Service  work  should  be  limited 
to the replacement of bulbs, light sources and electrical fuses. Should a defect occur, 
please contact your dealer or KERN Service. 

 
 

7.1  Changing the bulb 

The devices in the OBE range all have LED lighting. In general, LEDs are very long-
lasting.  However,  if  you  still  suspect  that  a  bulb  is  broken,  then  please  contact  our 
Service Department. 
 
 

7.2  Changing the fuse 

Switch the device off and unplug it. Unscrew the fuse housing on the right next to the 
mains cable socket, remove the old fuse and fit a new fuse. Screw the fuse housing 
back in.
