Status indicator LEDs
Lift signal
A red LED above this symbol shows that the lift sensor has triggered.
Note: Vibrations or collisions can also trigger the lift sensor.
If this sensor is triggered for less than one second, the Robotic Mower will resume its work
schedule immediately.
If the lift sensor is triggered for more than 1 second but less than 8 seconds, the Robotic
Mower will stop operating for a short amount of time, then restart. If the Robotic Mower's lift
signal is triggered for more than 8 seconds, this will trigger the anti-theft system. The device
will lock itself and an alarm will sound.
Boundary wire signal
The boundary wire emits an electromagnetic signal. The Robotic Mower uses this
signal to determine if it is within the cutting area.
The red LED above this symbol flashes when the device does not receive the "within
boundary" signal. In this case, the Robotic Mower will stop mowing immediately.
Low battery symbol
This LED will turn on when the battery charge is low. In this case, the Robotic Mower
will immediately return to the docking station.
Charging
This LED will flash while the battery is charging. A continuous LED indicates a fully
charged battery.
While charging, the boundary signal receiver is powered off to save energy. This can cause
the "boundary wire signal" LED to turn on.

OPERATION
Working time setting
The above buttons let you choose the mower's daily working hours.
Please refer to the below table for the recommended working time per day, depending on the
working area.
The current working time is indicated by the illuminated button.
A flashing button means that the device has already worked the respective hours that
day.
Note: The average working time with a fully loaded battery is less than the minimal working
time setting of 4 h. When the Robotic Mower returns to the docking station, the clock does
not stop. The charging time counts as working time.

After the working time is selected, the corresponding LED will be lit up LED flash means out
of working time.
Signal setting
To avoid interference with a second Robotic Mower, there are two different boundary signals
available.
Be sure to choose the same signal (S1 or S2) for the docking station and the Robotic Mower.
Use the control at the back of the docking station to switch between signal S1 and S2.
