Checking The Installation - Husqvarna 420 Operator's Manual

3.7 Checking the Installation

Check the loop signal by inspecting the indicator lamp on
the charging station.
• Solid green light = good signals.
• Flashing green light = loop system is shut down and
the robotic lawnmower is in ECO mode, see 6.9
Settings on page 61.
• Flashing blue light = interruption in the boundary loop,
no signal.
• Flashing red light = interruption in the charging
station's antenna plate. The fault should be rectified
by an authorized dealer.
• Solid blue light = weak signal. This may depend on
the boundary loop being too long or that the wire is
damaged. If the robotic lawnmower still works, this is
not a problem.
• Solid red light = fault in the circuit board in the
charging station. The fault should be rectified by an
authorized dealer.
If anything other than a solid green light or flashing light
is shown, see chapter 9.3 Indicator Lamp in Charging
Station page 84.
