FIGHTER 2010 is usually placed next to a house wall,
which gives a directed sound distribution that should
be considered. Accordingly, you should always at-
tempt to find a placement on the side that faces the
least sound sensitive 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.
FIGHTER 2010 works in its low power step (step 1)
during spring, summer and autumn, and in its highest
power step (step 2) during winter.
