WARNING
General safety instructions for setting up on a tripod:
For every system setup on a tripod, use a tripod that is designed according to the total weight.
When setting up a system on uneven surfaces, such as gravel or grass, always put a pressu-
re-resistant surface under all four spindle feet or the tripod legs! Make sure that all four spindle
feet or the tripod legs rest completely on the pressure-resistant shims and that the surface can
withstand the total weight!
Note that depending on the system design, either the front or rear spindle feet may be able to
carry more weight!
Make sure that no one can trip over your system structures, or over individual components!
This is especially true for all pressure-resistant shims, tripod legs and bracing ropes!
Any influences on your system setup, such as leaning against objects (or people) and flying
objects around, be refrained from!

5. Transport and storage
The original packaging is unsuitable as permanent storage and transport packaging.
When transporting and storing the unit, it is important to ensure that the surface of the swi-
vel bracket are not damaged. Moisture can penetrate where steel surfaces are exposed by
scratches and result in corrosion.
In addition, appreciable dust deposits may considerably impair the functionality of a loudspe-
aker membrane. For this reason, the loudspeakers should be transported and stored in a
safe, careful, dry and largely dust-free manner.
