Sounds
Place the cursor on Start and press OK. The buzzer
then emits a short sound signal at the same time as
a note is shown on the display.
Press BACK to exit the test.
Charging station
This function is used to quickly check that there is a
signal for A, F, N and the Guide wires. The test also
shows whether the mower is receiving a charge
from the charging station.
Place the mower in the charging station and start
the test.
NB! The robotic lawnmower must be synchronized
with and placed in the charging station to be able to
conduct the test. Use the New loop signal function
in the Security menu to synchronize.
It is recommended to use Info - Battery and Info -
Loop to carry out a more exact inspection of signal
strength and charge current.

sure the GPS module (430X) or Automower

strength of the GPS signal reception. To
