S2125 is usually placed next to a house wall, which gives a
directed sound distribution that has to be taken into consid-
eration. Accordingly, when setting up, you should always
attempt to select the side that faces the least sound-sens-
itive neighbouring area.
The sound pressure levels are further affected by walls,
bricks, differences in ground level, etc and should therefore
only be seen as guide values.
