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.
Mark of positive side
Be sure to remove the battery when the hearing aid is not to be
used for an extended period of time.
Battery life: Approx. 177 hours (PR-48 or 13, for continuous use)
Battery life will change depending on the operating
condition.
Putting on Hearing Aid
1. Hold the hearing aid as shown and put it on your ear.
2. Insert the earpiece into your ear.

Above illustration shows HB-23PT. HB-23P is not equipped with induction coil (T position of O-T-M switch), Tone switch and MOP control.
The parts drawn on the right side of the above picture are consumables. Please ask your supplier to buy them.
* Do not touch the control. Any adjustment should only be performed by your Audiologist or hearing aid dispenser.

T M
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
Set to "M" to hear sounds through the microphone.
When taking off the hearing aid, set the switch to "O". If not, acoustic
feedback may result.
Volume Control
When you remove the hearing aid from your ear
Adjust the sound volume to the most
comfortable level with the volume control. The best position of the control will
depend upon the distance and voice of
the person with whom you are talking;
readjustment may be necessary.
When using the hearing aid for the ﬁrst
time, set the control for a comfortable
level, then reduce the volume slightly.
Set the switch to "O" to power off
and remove the hearing aid from
your ear.
When removing the hearing aid with
the switch setting "M" or "T", acoustic feedback (high-pitched sounds)
might be heard.
