How to care for hearing aids
Regular maintenance can make the hearing aid more durable and maintain a good sound.

Here are some tips for caring for hearing aids
Store the hearing aids away from electrical appliances (refrigerators, TVs, etc.).
Do not let the hearing aid overheat or undercool.
Keep dry, as sweat or moisture can damage the hearing aid. Wipe the sweat or moisture on the hearing aid with a cloth during the day. Do not wear it while bathing, swimming or rainy. In the evening, place the hearing aid in a box containing silicone. Do not use perfume or other sprays.

To extend battery life, turn off the power when you are not using the hearing aid.
Keep the battery clean and remove the battery when the hearing aid is not in use for a long time, such as when the child is sleeping at night.
Change the battery frequently. Check if you need to change the battery, turn the volume up to the maximum, and if you hear a beep, the battery is OK. If you can't hear the sound, the battery should be replaced. If the number of times the battery is replaced more than usual, there may be a problem with the hearing aid.
Place the battery in a cool, dry place. After removing the battery from the refrigerator, wait until it returns to room temperature.
The hearing aids are inspected and the hearing aids are regularly taken to the hospital or purchased store/pharmacy for professional examination.

Hearing aids sometimes require maintenance, and usually hearing aid repairs are only available in large cities. However, in some places, the Disabled Persons' Federation has begun to train some people, as well as monks to make ear molds and repair hearing aids.
