Caution: Danger to the tool and workpiece!
The wireless handwheel triggers an emergency stop reaction if the
radio transmission is interrupted, the battery is fully empty, or if
there is a defect. Emergency stop reactions during machining can
cause damage to the tool or workpiece.
Place the handwheel in the handwheel holder when it is not in
use
Keep the distance between the handwheel and the handwheel
holder small (pay attention to the vibration alarm)
Test the handwheel before machining
If the control has triggered an emergency stop you must reactivate
the handwheel. Proceed as follows:

key
The control opens a pop-up window where you
can set up the wireless handwheel configuration
Press the Start handwheel button to reactivate
the wireless handwheel
Select the END button
The MOD menu includes a function for initial operation and
configuration of the handwheel.
