Practical Advice
With the Bluetooth® Low Energy Module GCY 42, the
u
power tool is equipped with a radio interface. Local
operating restrictions, e.g. in aircraft or hospitals,
must be observed.
In areas where the Bluetooth® wireless technology is
u
not allowed to be used, the Bluetooth® Low Energy
Module GCY 42 and the button cell must be removed.

Solution
–
GCY 42, rotate the button cell or place means of insula-
tion between the button cell and Bluetooth® Low Energy
Module GCY 42.
If the application tool jams or snags, the power trans-
mission to the drill spindle will be interrupted. Always
hold the power tool firmly with both hands to with-
stand the forces this may create and adopt a position
with stable footing.
Switch the power tool off immediately and remove the
application tool if the power tool becomes blocked.
Switching on when the drilling tool is blocked may
cause high torque reactions.
