6. Loosen the nuts (D) and remove the SMB
unit carefully from the bracket.
The cable (A) between the battery (B) and
the SMB unit (C) may stay connected, in
order to avoid recalibration of the robot. Be
careful not to let the weight of the SMB unit
strain the cable!
In order to remove the SMB unit
completely, the connector R2.G must be
disconnected! This causes a necessary
recalibration of the robot!
