the specimen lights up).
If semiautomatic sectioning mode
has been selected before the unit
is switched off, the following saved
parameters are called up again
once the unit is switched back on:		•	Blade feed rate (SPEED)
•	Blade feed rate (SPEED)	•	Selected amplitude (AMPL)
•	Selected amplitude (AMPL)	•	Saved section thickness
			(AUTO FEED)

The LED illumination is switched on	ditto
automatically. You can switch it off
using the ON/OFF key.

The LED MAN is active. semiautomatic sectioning mode is enabled.
