are automatically combined to find the charging stationas quickly as possible but also with a minimum risk oftracks forming.In very complex gardens e.g. with many areas joined bynarrow passages, the amount of time required to find thecharging station is decreased by carrying out a numberof the manual settings outlined below.The robotic lawnmower always starts the search for thecharging station using an irregular search method.When the robotic lawnmower still cannot find thecharging station after a specific period of irregularsearching, it also starts to search for the guide wires andafter a further period also the boundary wire to followone of them into the charging station instead. This timeis specified in minutes and is known as delay time.Example:3 minute delay for Guide and 11 minutes for theboundary loop. The robotic lawnmower then searchesirregularly for 3 minutes and then searches for the guidewires for 8 minutes. If it has not found a guide wire afterthis period, the robotic lawnmower now also searchesfor the boundary loop.It is possible of course to specify the same delay time forboth the guide wires and boundary loop, for instance 5minutes. The robotic lawnmower then searchesirregularly for 5 minutes and when it does not find thecharging station, it continues to search either byfollowing the guide wires or the boundary loop,depending on which one it reaches first.In general a long delay time decreases the risk of tracksforming (the robotic lawnmower will find the chargingstation more often through irregular searches) but giveslonger search times. A short delay time gives theopposite effect, i.e. short search times with increasedrisk of tracks forming along the guide wires and/orboundary wires.3.17.4.1 OverviewThis overview summarises the selected settings for eachsearch method. To edit the settings for a method, selectthe method using left and right arrow keys followed byOK.3.17.4.2 GuideMove the cursor to suitable guide wire.Use the number keys to enter the delay time.The delay time is normally specified as a figure between0 and 10 minutes.3.17.4.3 Guide > Disable / EnableNormally the Guide method does not need to bedeactivated even if there is no guide wire installed.However, to disable the Guide method, selectDisableand press OK.3.17.4.4 Boundary loopUse the number keys to enter the delay time.This time is normally longer than forGuide as it isnormally better if the robotic lawnmower follows theguide wire home to the charging station. The delay timeis normally specified as a figure between 10 and 20minutes but can be shorter if the guide wire is notinstalled and it is unlikely that the robotic lawnmowercan find the charging station through an irregular search.If the robotic lawnmower passes a guide wire whilefollowing the boundary wire, it will stop searching alongthe boundary wire and instead start to follow the guidewire into the charging station.3.17.4.5 Boundary loop > Disable / EnableIf it is very inappropriate in the installation to follow theboundary loop, the Boundary method checkbox has tobe deactivated. To disable the boundary method, selectDisable and press OK.3.17.4.6 Boundary > More > Test right / Test leftTesting selected settings can be seen as a natural partof the installation.1. Place the robotic lawnmower about 3 m / 10 ft. fromthe boundary wire, facing the wire.2. The test function is found inInstallation >Findcharging station >Boundary.3. SelectMore and press OK.4. SelectTest right/Test left, and press OK.5. Press START and close the hatch.6. Check that the robotic lawnmower follows the guidewire all the way to the charging station and that itdocks with the charging station. The test is approvedonly if the robotic lawnmower is able to follow theguide wire the entire distance to the charging stationand docks at the first attempt. If the roboticlawnmower is unable to dock on the first attempt, itwill automatically try again. The installation is not30 - Installation 447 - 001 -
