Turn the instrument on with the power switch at the rear.
This is followed by a beep.
The instrument initializes.
The display (here only as an example) of the software version follows in the
four-digit LED display. This display disappears after 2 seconds and "0000" is
displayed.
After the microtome is switched on, the display fields and LEDs of all acti-
vated functions are lit up on the instrument's control panel and display field.
The three-digit LED display indicates the last value set for the section thick-
ness or trimming thickness, depending on which setting was last activated.
This is indicated simultaneously on the control panel and microtome.
The LED of the active mode (here the section thickness) is illuminated in
green.
When the red LED in the E-STOP field (2) on the control panel of the instru-
ment is illuminated, either
• the emergency-stop function has been activated
(the EMERGENCY STOP button is pressed or the foot switch depressed)
• the dummy plug (or the optional foot switch) is not correctly connected
to the jack, or not connected at all.
If the yellow LED in the M-STOP field (4) of the control panel is lit, the me-
chanical handwheel lock or the handwheel brake ( Item 3 in Fig. 3 ) is acti-
vated.
The instrument cannot be used as long as the LED is lit.
