8. Open the SMB cover carefully.
The cable between the battery and the SMB-unit may
stay connected, in order to avoid an update of the
revolution counter. Be careful not to let the weight of
the cover strain the cable!
In order to remove the cover completely, the
connector R1.G must be disconnected! This causes
a necessary updating of the revolution counter!

board is located in frame.
