The ThinTube and dome should be changed every third month
or sooner if the ThinTube becomes stiff or brittle. We recommend
that you have your hearing care professional change the dome for
you. If your hearing care professional instructs you to change the
domes yourself, make sure that they are securely fastened to the
ThinTube before inserting them in your ear. A failure to change
the domes in accordance with the instructions could result in
injury.
