How to Clean the Centra Life Hearing Aid

Your Siemens Centra Life hearing aid is a miniature electronic digital device. It is a workhorse that runs 14 to16 hours a day in moist, humid, waxy ears at 98.6 degrees during hot summers, cold winters and rainy seasons. If you want your hearing aid to work at top performance and last for years you need to take good care of it. That means regular cleaning. Your Siemens Centra Life has three parts that need to be checked and cleaned on a daily basis: the hearing aid, thin-tube and dome.

Instructions

• 1

  Wipe clean the body of the hearing aid with a clean cloth or tissue paper to remove dirt, oils and perspiration.

• 2

  Brush across the two microphone openings to clear any dirt or debris that would block sound from entering the hearing aid.

• 3

  Brush across the tip of the dome that covers the end of the thin-tube. This will clear ear wax that would block sound from leaving the thin-tube. Be careful not to push the bristles into the dome as this may push ear wax deep into the tube.

• 4

  Gently squeeze the sides of the dome with the clean cloth or tissue paper to remove any wax that may adhere to that area.

• 5

  Replace the dome if it tends to easily slide off the thin-tube.

• 6

  Grasp the thin-tube housing where it connects to the hearing aid with your thumb and fore-finger. Gently rotate the housing one quarter-turn counter-clockwise to disconnect the thin-tube unit from the hearing aid.

• 7

  Place the nozzle of the compressed air can into the opening of the thin-tube housing and blow out any wax, dirt or fluid that may be into the thin-tube.

• 8

  Connect the thin-tube to the hearing aid by rotating the housing one quarter-turn clockwise and gently pushing at the same time.

• 9

  Open the battery compartment and inspect the battery for rust or corrosion. If the battery is corroded, it will have a greenish color.

• 10

  Inspect the interior of the battery door for rust or corrosion. Use a clean cotton swab to clean it.
