HOW TO USE YOUR FIRST HEARING AID

  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.

  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

  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.

  Do not expose the hearing aid to the heat from stoves, etc. Also, 

avoid leaving it in places with high humidity.

  Operate the controls with care. Do not press hard.
  If the hearing aid is dropped in water, wipe with dry cloth and ask 

the dispenser for check.

  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.
