TROUBLESHOOTING
Message Cause Action
Weak GPS signal Not applicable for Automower® 320.
The GPS signal is weak for the current
working area. GPS assisted navigation
cannot be used.
If the message appears often, turn off the GPS
assisted navigation and instead use the manual
settings for Lawn coverage. See 6.8 Installation on
page 49.
Guide calibration failed The robotic lawn mower has failed to
calibrate the guide wire.
Check that the guide wires are installed according
to the instructions, See 3.6 Installation of the guide
wire on page 28

9.3 Indicator lamp in the charging station

For a fully functional installation, the indicator lamp in the charging station must emit a solid green light. If something
else appears, follow the troubleshooting guide below.
There is more troubleshooting help on www.automower.com. If you still need help with troubleshooting, please contact
the local dealer.
Light Cause Action
Solid green light Good signals No action required
Green ashing light The signals are good and ECO mode
is activated.
No action required. For more information on ECO
mode, see 6.9 Settings on page 59.
Blue ashing light The boundary loop is not connected
to the charging station
Check that the boundary wire connectors are
tted properly to the charging station. See 3.5
Connecting the boundary wire on page 27.
Break in the boundary loop Find out where the break is. Replace the
damaged section of the loop with a new loop
wire and splice using an original coupler.
Red ashing light Interruption in the charging station’s
antenna
Contact the local dealer.
Solid blue light Weak signal as the boundary wire is
too long. Max length is 800 metres.
No steps have to be taken if the robotic
lawnmower operates as expected.
Shorten the boundary wire by reducing the
working area or replacing islands with barriers
the robotic lawnmower can collide with.
Weak signal due to damaged
boundary wire
Since it is difcult to locate where the wire
is damaged it is recommended to lay a new
boundary wire for the entire working area.
Solid red light Defective circuit board in the
charging station
Contact the local dealer.
