Keep your ear canals clean
Repeated use of a hearing aid can lead to an accumulation of earwax in the ear canal. This build-up of earwax can lead to a blockage of the ear canal and further decrease your hearing capacities or even cause whistling (feedback) when using your hearing aid. Keep your your ear canals clean. If an obstructive earwax plug is blocking it, consult an ENT doctor to remove it.
Care instructions for the AZUR hearing aid
During use, earwax and dust can deposit on the various components of your hearing aid and affect its proper functioning. In order to avoid this, we recommend that you pay attention to the maintenance of your hearing aid and that you observe the following instructions.
STEP 1 : Cleaning the bio-medical plastic shell (D)
Placed on the auricle, the shell and its components (notably the microphones) are subject to humidity, dust and micro-dirt from the ambient air. Clean the shell with a soft, dry cloth after each use of your hearing aid.
STEP 2 : Cleaning the microphones (B)
The microphone is a fundamental element of the functioning of a hearing aid. Its role is to capture sounds that are then amplified and played back to the user. AZUR has 2 microphones (B) located on the shell (D). Clean the microphones regularly by scrubbing them with the provided brush, so that no deposits prevent them from working properly.

STEP 3 : Cleaning the silicone eartip
The silicone eartip is located at the end of the tube (A) and covers the sound outlet. Because it is positioned in the ear canal, it is common for earwax to be deposited on it, affecting the sound reproduction quality of the hearing aid. To avoid this situation, the silicone eartip must be cleaned regularly. To do this, please :
- Remove the silicone eartip from the tube (A),
- Scrub the eartip with the dedicated brush,
- If necessary, rinse the eartip under warm water. In this case, make sure that it is completely dry before putting it back on the tube.
For reasons of hygiene, we recommend changing the tip once or twice a month.
STEP 4 : Cleaning the tube (A) and the sound outlet (E)
The sounds picked up by the microphones (B) are guided to the ear canal through the tube (A) and delivered to the auditory system through the sound outlet (E) which is located under the silicone eartip. To ensure that your hearing aid works optimally, make sure that the tube and the sound outlet are kept perfectly clean, unobstructed by any deposits that would slow down the reproduction of sound. To do this, please :
- Remove the silicone eartip from the tube (A) and clean it (see step 3),
- Remove the tube (A) from the shell (D),
- Slide the black wire into the tube, until it comes out of both sides of the tube,
- Then remove the wire, replace the tube and the eartip.

Remove the tube | • At the point where the tube (A) is attached to the shell (D), a red line is marked on the tube. • This line is positioned opposite a red dot located on the hearing aid, in the center of the shell (D). • Hold the tube attachment point between your thumb and index finger and turn it 90° to the second red point on the outside of the unit. • The tube is disengaged : pull gently on the tube to remove it from the shell. |

Put the tube | • Insert the fixing point of the tube in its space on the shell, positioning the red line on the side, facing the external point. • Then turn the attachment point 90° to position the red line over the first red point, located in the center of the shell (D). |

STEP 5 : Store the AZUR hearing aids in their rechargeable storage box
When you are not using your hearing aids, store them in their box, away from dust and shocks. Make sure your box is charged. Do not leave your hearing aids on charge for more than 5 hours, as this may damage the battery.
