Thin tubes and domes
1. Remove the thin tubes from the hearing aids by unscrewing them counter-clockwise.
2. Wipe down thin tubes and domes with a damp cloth.
3. In order to clear the thin tube of moisture and debris, push the black cleaning wire through the thin tube,
beginning at the opposite end of the dome.
NOTE: We recommend that you change the thin tube and dome systems every three months. If the
components get stiff or brittle, change them sooner.
