Maintenance
The micro tube and dome should never be submerged
or rinsed in water, as there is a risk that a water
drop may become lodged in the micro tube. If this
should occur, it will prevent sound from coming
through the micro tube, and may be harmful to the
hearing system’s electronics.
The micro tube and dome should be changed every
three months or sooner if the micro tube becomes
stiff or brittle. Only your hearing care professional
should change the dome. This is to prevent the
dome from detaching from the micro tube during
insertion into the ear.
