53 MAN (LED)
Lit in manual mode of operation. - LED MAN must be on in order to be able
to access/activate the control buttons in area 5.
54 RETRACT (LED)
Lit (also when retraction = 0) while the specimen sledge is in return stroke -
see also area 2.2 ‘Setting the retraction parameters’.
55 CUT (LED)
Starts emitting light when the sledge reaches the rear limit position (sledge
being moved via buttons (56/57)).
56 Sledge fast forward (button)
Sledge moves only while the button is being held.
57 Sledge slow forward (button)
Sledge moves only while the button is being held.

61 Sectioning/milling window (limitation of the sectioning/milling stroke)
Setting the sectioning window:
-
Move the sledge to the first limit position you wish to set (use buttons
56 - 59).
- Press and hold button (61) until LED (62) starts flashing - then move the
sledge on to the second desired limit position.
- Press and hold button (61) once again, until LED (62) stays lit, thus indi-
cating that both positions have been stored.
Deleting the sectioning window:
Press and hold button (61) just once until the LED starts flashing - the
instrument will return to maximum sledge stroke length as soon as the
LED stops flashing after a few seconds.
62 LED ‘Sectioning / milling window’ in button (61):
- Flashes - while the sectioning window is being set.
- Stays lit - when a sectioning window has been defined.
- Off - when no sectioning window has been defined.
The sectioning window settings cannot be changed while section-
ing/milling is in progress; changes are possible only in MAN mode.
