The horizontal cutting path can be
reduced to the specimen size. The
two cutting window edges can be
adjusted and changed indepen-
dently. Holding the key down for a
longer duration (audible warning
signal) sets the beginning or end
(depending on the key) of the cut-
ting window to the maximum val-
ue. Smallest possible cutting win-
dow: 0.5mm. If a window smaller
than 0.5mm is set or the user re-
verses the beginning and end, the
last entered value is accepted and
the previous value is set to the max-
imum value. The cutting window is
not saved when the instrument is
switched off; however, it is retained
when you switch from automatic
mode (AUTO) to semiautomatic
mode (MAN).
