For Pro20 and Lucid30, you can reassemble the tube and domes by your self. For RIC02, you just need to reassemble the domes.
For Pro20 and Lucid30,
1. Remove the tubing.
Start by rotating the tubing base counter-clockwise. For the threaded style tubing, it should turn very easily, with little to no resistance. Continue to rotate the tubing base counter-clockwise, like a bottle cap, until the tubing and hearing aid body separate.
2. Reassembling the Tubing.
To reassemble your hearing aid, we are going to put the tubing back on the hearing aid body. Again, this depends on whether you have the threaded style or snap-on style tubing. If you have the threaded style tubing—the type that rotated off the hearing aid—simply rotate the tubing base back onto the hearing aid, this time in a clockwise motion. Make sure the tubing is flush with the sides of the hearing aid body and the tubing is facing forward when you’re done. If you have the snap-on style tubing, all you need to do is push the tubing directly onto the base of the hearing aid. You don’t need to rotate the tubing on. Just push the tubing and the hearing aid directly together. The tubing should just pop on the hearing aid body and you should be good to go. Make sure the tubing base is flush with the sides of the hearing aid.
