If the emitting signals of each indicator get overlapped, no setup for cleaning area will be
made.
In this case, it will become as if no indicator were installed.
It is recommended that you not install indicators in a place with the charger in it.
The emitting signals of the charger (in the radius of 5 meters) may be overlapped with the
signals of the indicators, causing all signals to be ignored.
