Fault:
The robotic mower operates at the wrong
times.
Possible cause:
– Date and time incorrectly set
– Active times incorrectly set
– Machine has been operated by
unauthorised persons
Remedy:
– Set the time and date (Ö 11.13)
– Set the active times (Ö 11.6)

"High" (Ö 11.16)
Fault:
The robotic mower fails to operate during
an active time
Possible cause:
– Battery is charging
– Automatic mowing switched off

– Rain detected
– Weekly mowing duration has been
reached, no further mowing operations
required that week
– Message is active
– Flap open or not present
– Docking station not connected to power
supply

(Ö 15.7)
– Switch on automatic mowing (Ö 11.5)
– Release the active time (Ö 11.7)

information is available from your
specialist dealer. #
– Check the power supply. When the
robotic mower detects a wire signal
again after a periodic check, it resumes
the interrupted mowing operation. This
means that it can take several minutes
before mowing operation is
automatically resumed following the
power failure. The intervals between
the individual periodic checks increase,
the longer the power failure lasts.
