6.3 Loop signal

When measuring loop signal strength the mower should
be placed in the charging station. Use the Tools - Test -
Charging station menu function to check that the signal
strength is within the expected values. The test provides
a quick answer to if the charging station generates all
signals and the mower can detect these signals.

6.4 Troubleshooting the loop signal

Always start by checking the LED in the charging
station. This usually provides a good indication of where
troubleshooting should begin.
