Sennheiser Set 810 S Bedienungsanleitung Seite 36

The transmitter automatically switches to trickle charging so that the bat-
tery cannot be overcharged. The receiver can remain in the charging com-
partment even when the battery has been fully charged.
A battery has a service life of 1-2 years and should be replaced if the ope-
rating time decreases.
Sennheiser batteries can be recycled. Please dispose of the batteries as
special waste or return them to your specialist dealer. To protect the envi-
ronment, only dispose of totally exhausted batteries which cannot be re-
charged.
