How to change ReSound wax guards

Remove the rubber dome from the receiver by pinching and peeling it off. Take a black plastic stick from the wax guard pack—insert the empty end into the old wax guard and pull it out. Flip the stick over and insert the new wax guard (on the other end) into the same spot by gently pushing straight in. Remove the stick, replace the dome, and you're done. Change wax guards monthly or whenever sound becomes weak.
