We recommend that your hearing care professional changes the dome
for you, since failure to change the domes in accordance with the
instructions could result in injury. If you choose to change the dome
yourself:
1. Push the dome over the grooves on the tube to mount it (1) + (2)
2. Make sure that it is securely fastened
1. Remove the tube from the instrument before cleaning by
unscrewing it
2. Use a damp cloth to clean the tube
and dome on the outside
3. Use the black cleaning rod to “push”
any debris out of the tube. The clean-
ing rod should be inserted where the
tube attaches to the instrument and
pushed all the way through the tube
and out through the dome
It is not recommended to submerge or rinse the tube and dome with
water, as there is a risk that water can close the tube. If this should
occur, it will prevent sound coming through the tube, and may be harm-
ful for the instrument’s electronics.
The tube and dome should be changed every third month or sooner if
the tube becomes stiff or brittle.
