HOW TO USE YOUR FIRST HEARING AID
z
Any hearing aid cannot return level of your hearing to normal or
halt further hearing deterioration, but proper use of your hearing
aid can help you hear what is going on around you and let you
get more enjoyment of life.
z
If this is your first hearing aid, you - like most new users - will
probably be surprised at the loudness of the sounds, and after using
it for a short while, you may even feel that it is too noisy. The following
three tips are important in overcoming your concerns.
1) Read this manual and become familiar with the hearing aid's
various mechanisms and how to use them correctly.
2) First, use your hearing aid in a quiet place and listen to quiet
sounds and give yourself sufficient time to get accustomed
to the sound of your hearing aid.
3) If any physical problems develop, consult your doctor.
FOR KEEPING YOUR HEARING AID LONGER
z
Always keep the hearing aid clean. Clean the hearing aid with
dry cloth periodically and also remove earwax plugged in the
earpiece or earmold using eyebrush or toothbrush.
z
Do not expose the hearing aid to the heat from stoves, etc. Also,
avoid leaving it in places with high humidity.
z
Operate the controls with care. Do not press hard.
z
If the hearing aid is dropped in water, wipe with dry cloth and ask
the dispenser for check.
z
Do not pick the microphone with nail, pin, etc., because this may
damage the microphone.

Do not disassemble or attempt any repairs by yourself. Ask the
dispenser for repair.
