USER GUIDE
It is not recommended that you submerge or rinse
the sound tube or dome in water. Water may become
lodged in the sound tube. If this should occur, it will
prevent sound from coming through the sound tube,
and may be harmful to the electronics of the hearing
aid.
The sound tube conducts the amplified sound from
the hearing aid to your ear. It is important that the
sound tube and the dome fit correctly into your ear. If
the sound tube or the dome irritates your ear in any
way and prevents you from wearing your hearing aid,
please contact your hearing healthcare professional.
The sound tube and dome should be changed every
third month, or sooner if the sound tube becomes stiff
or brittle.
The Sound Dome
We recommend that you have your hearing healthcare
professional change the domes for you. If your hear-
ing healthcare professional instructs you to change
the domes yourself, make sure that they are securely
fastened to the sound tube before you insert them in
your ear. A failure to change the domes in accordance
with these instructions could result in personal injury.
