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

O-T-M switch
O:
Hearing aid is turned off and no sound is heard.
T:
Set to "T" when the hearing aid is used for telephone or
loop system.
When the switch of the hearing aid is set to T, noise may be
heard in the vicinity of electromagnetic fields, such as generated
for example by electronically secured gates or similar.
M:
Microphone for ordinary use. This is the normal operating
position.
Removing Hearing Aid
1. Set the switch to "O" (power off) before removing the hearing aid. If
the switch is left in the "M" or "T" position, acoustic feedback
(howling) may occur.
2. Be sure to set the switch to "O" and take out the battery, when not
using the hearing aid.
Turn-on precaution
If you switch the hearing aid off and then immediately on again,
there may be no sound, but this is not a defect. In such a case,
return the switch to "O" (Off), wait for at least 10 seconds, and
then set the switch to "M" or "T" again.
