the
battery (PR536
or 10 zinc-air battery) before loading.
2. Open the battery holder.
3. Insert a PR536 or 10 battery sideways
into the battery holder. You do not have
to worry about the polarity.
4. Close the battery holder.
Battery life (PR536 or 10, for continuous use)
Approx. 100 hours
- Battery life will change depending on the operating
condition.
When remove the battery,
grasp it and pull it up. Be sure
to remove the battery when
the hearing aid is not to be
used for long time.
Inserting Hearing Aid in Your Ear
This hearing aid does not have a power switch. The battery
holder also functions as power switch.
Power/OFF: Open the battery holder.
Power/ON: Close the battery holder firmly.
1. Open the battery holder slightly, so that the hearing aid is set
to the OFF condition.
2. Hold the hearing aid so that the pull-out wire is at the rear,
lightly pull the auricle back and insert the hearing aid straight
into the ear.
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 prob-
ably 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 sound outlet using eyebrush or tooth
-
brush.
Do not expose the hearing aid to the heat from stoves, etc. Also,
avoid leaving it in places with high humidity.
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.

If the hearing aid is hard to insert
in a straight motion, slowly rotate
it in the direction indicated by
the arrow in the illustration, and
lightly push it in.
Note: If the hearing aid is inserted with the battery holder
closed (ON), acoustic feedback may occur.

Turn-on precaution
If the hearing aid is turned on again immediately after turning it off,
there may be no sound, but this is not a defect. In such a case,
turn the power off (open battery holder) and wait 10 seconds.
Then turn the power on again (close battery holder).
Removing Hearing Aid
Carefully pull the wire to remove the hearing aid. When acoustic
feedback occurs, open the battery holder (power off). Acoustic
feedback may stop. Then pull the wire first sideways and then
up.
Adjusting the Controls
This hearing aid is a digital type. Any adjustments must be done
at the dealer. For details, please contact the dealer.
Cleaning your Hearing Aid
We recommend that you clean
your hearing aid twice a week
(more or less needed) to remove
any earwax that may build up as
a result of regular use. Too much
earwax build up can prevent your
hearing aid from working.
Hold the hearing aid as the il
lustration, brush off the earwax
of the sound outlet.
