6.2 Reflected light
OKO-1, OKN-1
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.
All 8 screws on the rear edges of the lamp housing have to be removed.
Thus the holder of the halogen lamp can be separated from the rest of the housing.
The defective bulb can be pulled out of the socket and be replaced with a new one.
Finally the lamp housing is screwed together again.
