small volume, a large number of components contribute to handling all the
functions. their mechanical action inevitably leads to a certain amount of
wear and tear, which may be controlled by maintenance consisting of renew-

deteriorate and must be periodically replaced, ideally every two years.
moreover, we recommend an annual water-resistance test, which takes only
a few minutes, performed by your authorized B
