Maintenance and
cleaning
It is not recommended to submerge or rinse the thin tube and dome
with water, as there is a risk that a water drop may become lodged
in the thin tube. If this should occur, it will prevent sound coming
through the thin tube, and may be harmful for the instrument’s
electronics.
The thin tube and dome should be changed every few months or
sooner if the thin tube becomes stiff or brittle. When changing the
domes yourself, make sure that they are securely fastened to the
thin tube before inserting in your ear. A failure to change the domes
in accordance with the instructions could result in injury.
