can recognize obstacles and the work area in
which there is no longer any lawn. When the
robot lawn mower comes across an obstacle
or no longer detects any lawn, it will stop and
begin to mow again in a random direction.
Because of the camera unit it is impossible
for the robot lawn mower to work in twilight or
during the night. The selected work window
should lie within daytime hours when there is
enough daylight for the robot lawn mower to
work reliably. This also helps to protect semi-
nocturnal animals such as hedgehogs.

Distance sensors:
The robot lawn mower is equipped with dis-
tance sensors (16) which enable it to detect
obstacles along its path. When the robot lawn
mower comes across an obstacle, it will stop
and begin to mow again in a random direc-
tion.
•
Magnetic tape sensor:
The robot lawn mower is equipped with a
magnetic tape sensor for recognizing a mag-
netic tape (27) lying on the ground. When the
robot lawn mower comes across a magnetic
tape it will stop and begin to mow again in a
random direction. The magnetic tape serves
as a virtual boundary for creating areas of the
garden where the robot lawn mower is not
allowed to mow.
•
Rain sensor:
The robot lawn mower is equipped with a rain
sensor (5) to prevent it from operating in the
rain. When the robot lawn mower detects rain
it will return to the charging station (19) and
and be completely recharged there. When the
rain sensor (5) is dry again, the robot lawn
mower will begin working again provided it is
still in an active time window. When the rain
sensor (5) is triggered, the rain sensor LED
(53) will light up. Do not short-circuit the two
metal sensors with metal or any other con-
ductive material. This will impede the correct
operation of the robot lawn mower.
•
GNSS module:
The robot lawn mower determines its position
and the position of the charging station (19)
by means of a global navigation satellite sys-
tem (GNSS). This helps the robot lawn mower
to fi nd its way back to the charging station
(19). The robot lawn mower can use the
GNSS module to determine the local times
for sunrise and sunset so that it is prevented
from mowing in twilight and during the night.
This also means that the robot lawn mower
can work reliably with its camera unit (15).
GB
The robot lawn mower also uses the GNSS
module at all times to determine its distance
from the charging station (19). The robot lawn
mower is allowed to move no more than 1000
m from the charging station (19) or else the
GNSS LED (54) will turn yellow and the robot
lawn mower cannot be operated in Main Area
mode. The mower's distance from the char-
ging station (19) is irrelevant for operation in
Secondary Area mode.
5.3 Preparations
If the grass is taller than 60 mm it has to be
shortened fi rst to avoid exposing the robot lawn
mower to excessive load and adversely aff ecting
its operating effi ciency. Use a conventional lawn
mower or trimmer to do this. Remove all loose
objects from the lawn which could get damaged
by the robot lawn mower or cause damage to the
robot lawn mower itself.
Check the mowing area, the lawn boundary and
any areas that you don't want to be mowed. The
following sections of these operating instructions
contain information about how you can defi ne
precise lawn boundaries and protect specifi c are-
as. Some obstacles can be detected by the robot
lawn mower in good time and require no elabora-
te protection.
Have the following tools ready: A hammer, tongs,
a wire stripper and a spirit level (optional).
5.3.1 Calculating the gradient of the lawn
The robot lawn mower can cope with gradients
of up to 25%. You therefore need to avoid steeper
gradients. The gradient can be determined on the
basis of height divided by distance (Fig. 3a).
Example: a/b = 25 cm/100 cm = 25 %
5.3.2 Installing the battery
A battery (A) from the Power-X-Change series
is needed to operate the robot lawn mower. Im-
portant: Depending on the model of your robot
lawn mower, it might not come complete with the
battery (A). Open the battery compartment cover
(9). Press the pushlock button of the battery (A)
and push the battery (A) into the mount provided.
Close the battery compartment cover (9) and
make sure that it latches in place correctly (Fig.
3b). To remove the battery (A), open the battery
cover (9). Press the pushlock button of the battery
(A) and pull out the battery (A).
