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.

so that the hearing aid is set to the OFF condition.
