The mains switch (green) is located in a recess on the
right side of the cryocabinet. In the OFF position it is on
'O‘; in the ON position it is on 'I‘ and illuminated.

•

Turn the instrument on with the mains switch.

The display of the temperature control unit will read
the actual temperature of the cryochamber.

After turning on, it will take approximately 5
seconds until the compressor starts operat-
ing.

Chamber illumination

Electric coarse feed

The electric coarse feed provides a rapid movement
of the specimen towards or away from the knife.
The specimen movement towards the cutting edge
must be observed carefully to avoid that the specimen
collides with the cutting edge which can cause severe
damage both to the knife and specimen!

Illumination ON
