HARMONIC ABSORBERS
Harmonic absorbers have been pre-installed under each shelf.
These absorbers are fixed to the shelf by a single Allen screw.
You mustn’t tighten this screw more than is necessary.
The absorber must stick to the shelf and not offer more than
a certain resistance if you try to make it pivot with your finger.
You should check to make sure that the absorbers remain parallel
and sufficiently tightened.
