6.3.2.10 Sound signal ("Buzzer")
This function is used to set an acoustic signal that sounds at the end of the
centrifugation run and also in the event of an imbalance or error message.
In order to activate the sound signal:
• Press the lid key five times and on the fifth time hold it down for approx.
two seconds.
• Proceed in the same way in order to deactivate the function.
After every change, the current status of the setting is displayed in the form
of a message running in the display ("Buzzer on" or "off").

6.3.2.11 Input lock
In order to prevent the centrifuge from being manipulated by unauthorised
persons, inputs can be disabled via the menu. Inputs via the keypad, i.e. for
starting or stopping a centrifugation run or for opening the lid, are enabled.
Activating a simple input lock:
• Turn the left function knob until the symbol "
" is displayed in the
upper left corner of the display. The centrifuge can only be started and
stopped, but the parameters cannot be changed.
As long as the symbol is displayed, the parameters of the centrifuge cannot
be changed.
Activating a permanent input lock:
• Press the start key three times and hold for approximately 2 seconds
when pressing it for the third time.
After the activation of this function, the padlock symbol flashes. The input
lock is activated. The centrifuge can only be started und stopped, but the
parameters cannot be changed.
• Proceed in the same manner in order to deactivate the permanent input
lock.
The current status remains active even if the centrifuge is switched off with
the help of the mains power switch.
