1, cleaning and maintenance:





Wipe with a soft, lint-free cloth or a
sponge soaked with detergent. When cleaning the hearing aid, use a professional
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. Then gently wipe the hearing aid with a soft cloth.





Earplug cleaning and disinfection method:
Take it off from the hearing aid, rinse it with water, or wipe it with alcohol.
After the earplugs are dry, install it on the hearing aid.





Note: Be careful not to pour liquid on the
instrument during cleaning. Make sure that no liquid enters the inside of the
instrument. Take special care when wiping to ensure that no water can enter.





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.





2, damp:





If the hearing aid is damp, do not use a
drying tool such as an oven, microwave or hair dryer, which can damage the
hearing aid.





The correct method: remove the damp
battery, open the hearing aid battery door, put the hearing aid on a towel and
store it in a safe place to achieve the purpose of flooding.





3. The preservation of hearing aids:





When the hearing aid is not in use, turn
the switch off and open the battery door to extend battery life.





If the hearing aid is not turned off, it
will make a "beep" howling that may cause the child or pet to notice
and cause unnecessary damage.





Therefore, store the hearing aid in a place
where children or pets are not easily found. If the hearing aid is not used for
a long time, store it in a special pocket and store it in a cool, dry place.





4, daily processing:





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.





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.





5, howling





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, consult a professional
such as the hearing aid customer service.
