* The communication connector serves for adjustment of
the hearing aid by the hearing aid professional. Using the
optional Audio input Controller and dedicated cable, ex
ternal equipment can be connected directly to HB-G4PE,
allowing the wearer to listen to the sound from various
devices.
Battery Placement
1. Set the O- -M switch of the hearing aid to
"O" (power off).
2. Peel off the sticker on the positive side of
battery (PR44 or 675 zinc-air battery).
3. Open the battery holder with the tip of your finger.
4. Insert a PR44 or 675 battery into the
battery holder. You do not have to
worry about the polarity.
5. Close the battery holder.
Battery life (PR44 or 675, for continuous use)
Approx. 180 hours
- Battery life will change depending on the operat
-
ing condition.
Putting on Hearing Aid
1. Place the hearing aid on 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
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.

3. Adjust the volume control to a suitable level.
Volume control
Higher numbers mean louder sound.
* Adjust the volume according to the situation (volume of
other voices, ambient noise, etc.).
O- -M Switch
O: Hearing aid is turned off and no sound is heard.
: Sounds through both the microphone and telephone coil can
be heard. Set to "
" position when using your hearing aid
for telephone or induction loop system in combination with
the MT balancer.
When the switch of the hearing aid is set to
, 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 "
" position, acoustic feedback
(high-pitched sounds) may occur.
2. Be sure to set the switch to "O" and take out the battery, when
not using the hearing aid.
No. 51960 07-06
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 "
" again.
Adjusting the Controls
This hearing aid is a digital type. Any adjustments must be done
at the dealer. For details, please contact the dealer.
