Message Cause
Trapped
The robotic lawnmower has got caught in
something.
The robotic lawnmower is stuck behind a
number of obstacles.
Outside working area The boundary wire connections to the charg-
ing station are crossed.
The boundary wire is too close to the edge of
the working area.
The working area slopes too much by the
boundary loop.
The boundary wire is laid in the wrong direc-
tion around an island.
Disturbances from metal objects (fences, re-
inforcement steel) or buried cables close by.
The robotic lawnmower finds it hard to distin-
guish the signal from another robotic lawn-
mower installation close by.
Empty battery
The robotic lawnmower cannot find the charg-
ing station.
The guide wire is broken or not connected.
The battery is spent.
The charging station's antenna is defective.
Wrong PIN code
Wrong PIN code has been entered. Five at-
tempts are permitted, and the keypad is then
blocked for five minutes.
No drive The robotic lawnmower has got caught in
something.
The working area includes a steep slope.
The guide wire is not laid at an angle on a
slope.

46 - Troubleshooting
Action
Free the robotic lawnmower and rectify the
reason for it becoming trapped.
Check if there are any obstacles which make
it hard for the robotic lawnmower to move on
from this location.
Check that the boundary wire is connected
correctly.
Check that the boundary wire has been laid
according to the instructions. See
wire on page 14 .
Try moving the boundary wire.
Place the robotic lawnmower in the charging
station and generate a new loop signal, see
Security on page 30 .
Check that the charging station and the guide
wire are installed in accordance with the in-
Installation of the guide wire
structions. See
on page 19 .
Find out where the break is and rectify it.
Battery on page 44 .
Replace the battery. See
Check if the indicator lamp in the charging
LED indicator lamp
station flashes red. See
on the charging station on page 50 .
Enter the correct PIN code. Contact your lo-
cal Husqvarna representative if you forget the
PIN code.
Free the robotic lawnmower and rectify the
reason for the lack of drive. If it is due to wet
grass, wait until the lawn has dried before us-
ing the robotic lawnmower.
Maximum guaranteed slope is 45%. Steeper
slopes should be isolated. See
page 17 .
If the guide wire is laid on a slope, it must be
laid at an angle across the slope. See
lation of the guide wire on page 19 .
Free the robotic lawnmower and rectify the
reason for the lack of drive. If it is due to wet
grass, wait until the lawn has dried before us-
ing the robotic lawnmower.
