Drive unit error The feed drive of the drive unit is

the instrument in for repair.
Timeout reached! The M 300 is attempting to set up
a Bluetooth connection with an
RD 18 or is searching for all existing
drive units and cannot establish a
connection.
This can happen sometimes if the
M 300 was switched off without
switching the RD 18 off, for ex-
ample.
Switch off both devices. Move the
reset switches (12) and (29) to the left
into the "0" position, then back to the
right again. Switch on first the RD 18
and then the M 300.
