2. If the mowing results are not satisfying, the cutting time can be adjusted to mow for a longer time (High) or for a shorter time (Low) 3.16.2 ECO mode Note: In order to minimize the risk for lawn wear in steep slopes, spiral cutting does not start in slopes steeper than 15%. ECO mode Use ECO mode The ECO mode function automatically turns off the signal in the boundary loop, the guide wires and the charging station when the robotic lawnmower is not mowing. ECO mode is suitable to use where there is other wireless equipment not compatible with the robotic lawnmower, for example some hearing loops or garage doors. When ECO mode is activated, the indicator lamp in the charging station flashes green. ECO mode means that the robotic lawnmower can only be started in the charging station and not out in the working area. In ECO mode, it is therefore very important to always press the STOP button on top of the robotic lawnmower, before removing the robotic lawnmower from the charging station. It is otherwise not possible to start the robotic lawnmower inside the working area. If the lawnmower has been removed by mistake without first pressing the STOP button, the lawnmower must be placed back in the charging station and the STOP button pressed. Then press the START button to be able to start inside the working area. Note: In ECO mode, always press the STOP button before removing the robotic lawnmower from the charging station. 1. Tap the On/Off bar to enable/disable Spiral cutting. 2. The intensity can be adjusted to trigger on a shorter or longer grass length. Choose an appropriate intensity level by tapping on Very low, Low, Medium, High or Very high. 3.17 Installation INSTALLATION Find charging station Lawn coverage Corridor width Exit angles Reversing distance Drive past wire 1. Tap the On/Off bar to enable/disable ECO mode. 3.16.3 Spiral cutting Use Spiral cutting Intensity Very Low Low Mid High Very high If the robotic lawnmower enters an area where it senses the grass is longer than average, it can change the movement pattern to spiral cutting. This means that the robotic lawnmower mows in a spiral pattern to faster cut the area with longer grass. It is possible to set the intensity of the spiral cutting. Very low / Low intensity means that spiral cutting begins less often. High / Very high intensity means that spiral cutting begins more often. The default settings are selected in a way that should suit most working areas. However, complex gardens may require changed settings. 3.17.1 Finding the charging station The robotic lawnmower can be set to search for the charging station in one or more of the following three ways: 1. Charging station signal 2. Follow boundary wire 3. Follow guide wire The default settings are set so that these 3 search options are combined to find the charging station as fast as possible, but also with a minimum risk of tracks forming on the lawn. The robotic lawnmower always starts by searching for the Charging station signal. After a specified time delay, it also uses Follow guide and Follow boundary wire. Common causes why the robotic lawnmower cannot follow the wire are: • Obstacles close to the wire have not been isolated. 362 - 002 - 06.02.2018 Installation - 27
