Low battery / Empty battery — Mower needs to charge or cannot find station
The mower's battery level is critically low or completely depleted, and it may be unable to return to the charging station. This can also indicate issues with the charging station or guide wire itself preventing the mower from locating its charge point.
Message beep and no start — START button not pressed
If the START button is not pressed before the robotic lawnmower's cover is closed, a message beep will sound, and the mower will not begin its operation.
Needs manual charging — Battery is depleted in MAN mode
When the robotic lawnmower is set to MAN (Manual) mode, it will mow until its battery is completely depleted. At this point, it will stop and display the 'Needs manual charging' message.
No loop signal — Boundary or guide wire signal absent
The robotic lawnmower is unable to detect the boundary loop signal, which is essential for its operation. This can stem from power issues, physical breaks in the wire, or incorrect installation/interference, causing the mower to stop.
Outside working area — Mower detects it's outside boundaries
The robot mower's display shows 'Outside working area', indicating it cannot detect the boundary wire signal or is positioned outside its defined work area. This can be caused by installation errors or external interference.
Product stopped by STOP button — Mower paused or disarmed
The robot mower has stopped due to the STOP button being activated. To resume operation, the PIN code must be entered and the start button pressed.
Red flashing light — Charging station antenna interruption
The charging station's indicator lamp flashes red. This indicates an internal problem with the charging station's antenna, which prevents it from sending or receiving signals correctly. This issue typically requires professional attention.
