It is important to keep the hearing aid clean and dry at all times. The battery door should be opened when the hearing aid is not worn, which will extend battery life.
If the hearing aid is equipped with a volume knob, you can use it to adjust the volume or switch the hearing aid.
When turning on the hearing aid, turn the volume knob forward or clockwise until it is in the proper position. To change the listening environment, if you want to increase the volume, rotate the knob forward. To decrease the volume, adjust the knob backwards or counterclockwise. The hearing aid can be turned off when it is rotated backwards.
If the hearing aid does not have a volume knob installed, insert the battery, close the battery door to activate the hearing aid, and open the battery door to close the hearing aid.
When the hearing aid is turned on, it makes a “beep” howling, especially when it is taken out or placed in a hearing aid. Howling is often caused by the amplified sound being reflected by the hand or other objects and then re-acquired into the microphone. When the hand or reflector is removed, the howling should stop. If there is a continuous howling, you should consult the professional assistant of the hearing aid.
Cleaning and maintenance
To develop the habit of cleaning the hearing aid every day, use the company’s brush to remove the earwax or other tiny particles that accumulate around the ear canal of the hearing aid, the volume adjustment knob and the battery compartment, and then gently wipe the hearing aid with a soft cloth. Never use solvents, cleaning fluids or oils to clean your hearing aids.
Because the hearing aids are very delicate, it is best to carry them on the tablecloth with a soft cloth or towel during cleaning and maintenance to avoid unnecessary damage or missing parts.
Once you have adapted your hearing aid, sometimes you will forget that it is working, so be sure to take out the hearing aid when you are swimming, bathing or using a hair spray. Of course, when washing clothes, check if there are hearing aids in your pocket.
If the hearing aid is wet, do not use a drying tool such as an oven, microwave or hair dryer – this can easily damage the hearing aid. Instead, remove the damp battery, open the hearing aid battery door, and place the hearing aid on a towel in a safe place to achieve the purpose of flooding.
Hearing aids are powered by button batteries; different types of hearing aids use different types of batteries, and the correct battery type is used. If you don’t know, you can consult a professional hearing aid option.
The performance of the battery varies depending on the model. For questions about battery life and performance model differences, you can consult a hearing aid professional.
When replacing the battery, it is best to place the hearing aid and the old battery on a table covered with a soft cloth or towel to prevent damage to the hearing aid or loss of the battery. Then use your fingernail to gently open the battery door. Note that the battery door should not be opened too much. After opening, you can push it out from the battery or take it out of the battery compartment.
Place the new battery correctly in the positive (+) direction of the battery compartment.
