Your Widex Senso hearing aid is a very intricate,
high precision electronic unit. It has been careful-
ly designed to withstand years of wear, under the
varying conditions the typical user finds them-
selves in each day. However, your hearing aid
may be damaged if exposed to extreme conditions,
severe blows, or general neglect.
To get full satisfaction from the quality and the
performance we have built into your new Widex
hearing aid, please handle it with care, and read
and follow the instructions carefully.
At the back of this manual you will find a trouble-
shooting guide, which will help you in situations
where your hearing aid does not perform accord-
ing to your expectations.
We hope you will be pleased with your new Widex
hearing aid!

Turning the hearing aid on
and off
The battery drawer also func-
tions as the on/off switch. The
hearing aid is turned on when
the switch is pushed upwards,
and off when the switch is
pushed downwards as illustrat-
ed.
The word “OFF” is clearly visi-
ble on the switch when the aid
is turned off.
Please remember to switch the
hearing aid off when it is not in
use. Remove the battery if the
hearing aid will not be used
again soon.

Automatic adjustment of
loudness
Senso P38 is equipped with a computer which has
been designed to adjust its loudness automatically
in accordance with the sound environment around
you. Several thousand times per second, Senso
analyses the surroundings and tailors its sound
accordingly.
With Senso you do not have to think about adjust-
ing the volume – it happens quite automatically.
Fine tuning loudness
If you have a Senso P38 with a
digital volume control, you can
fine tune the volume to make it
more comfortable when needed.
Press the lever upwards to
slightly raise the volume of the
automatic setting.
Press the lever downwards to slightly lower the
volume of the automatic setting.
When you raise the volume, you will hear a beep-
tone for each step the volume is raised. When the
maximum adjustment level is reached, a steady
tone will sound until you release the lever.
When you lower the volume, you will hear a deep-
er beep-tone for each step the volume is lowered.
When the minimum adjustment level is reached, a
steady tone will sound until you release the lever.
Note: Senso P38 is a powerful hearing aid. Avoid
prolonged use at uncomfortably high sound pres-
sure levels – it might damage your hearing.
For further information, consult your hearing
healthcare professional.

Telecoil (M-MT-T switch)
“M” (microphone): For nor-
mal use, the switch should be
in position “M” (microphone).
“T” (telecoil): Position “T” cuts
off the microphone and brings
the built-in telecoil into opera-
tion. The hearing aid can then
be used within any magnetic field or loop system
without background interference.
A loop system or magnetic field device can be fit-
ted to a TV or radio. Some public places such as
churches, theatres, cinemas and lecture rooms
are already equipped with a loop system.
Ask your hearing healthcare professional for
more information.
Note: The magnetic field in some telephones is
inadequate, in which case the “M” position should
be used.
“MT” (microphone + telecoil): If you want to
listen both via the microphone and the telecoil,
place the switch in mid-position “MT” (e.g. when
watching TV while still wanting to hear the door-
bell, telephone, or other persons speaking).

Changing the battery
Before inserting a new battery
in your hearing aid, remember
to remove the adhesive tab. Do
not use batteries on which there
is a sticky residue from the tab
or other unwanted substance
as this can block the battery
airholes.
Push the nail grip downwards
to swing open the battery draw-
er. The nail grip is located on
the opposite side of the on/off
switch at the bottom of the
hearing aid.
The battery must be placed
with the plus (+) sign visible, in
accordance with the plus (+)
sign on the battery drawer. If
the battery drawer does not
close easily, the battery is in-
correctly inserted.
When changing batteries, make sure to hold the
hearing aid over a table or a carpet to make it
easier to find a dropped hearing aid or battery.
Exhausted batteries: If you hear four rapid
beep-tones while wearing your hearing aid, it is
an indication that you should exchange the bat-
tery as soon as possible as the battery is nearly
exhausted. Once the battery is totally exhausted,
the hearing aid will be completely silent.
Exactly how long the hearing aid will function af-
ter the beep-tones varies from one case to anoth-
er. We recommend that you always have a spare
battery with you.
Never leave an exhausted battery in the hearing
aid. Exhausted batteries may leak, which could
damage your hearing aid.

Recommended energy source:
Zinc Air battery type 675
This hearing aid uses an environmentally friend-
ly, type 675 Zinc Air battery, which provides a
long lifetime when treated correctly.
Please note the expiry date code on the battery
pack stating how long the batteries will be good.
Do not remove the adhesive tab until just before
inserting the battery in the hearing aid. Once in-
serted, the battery will start functioning after a
few seconds. Operate your hearing aid with the
same battery until it is exhausted.
The lifetime of the battery depends on a number
of factors, such as the setting of your hearing aid,
how many hours you use it daily and the listening
environments in which you use it.
On occasion, a new battery may be exhausted be-
cause it was not sealed properly. If your hearing
aid does not work after you have replaced the bat-
tery, try inserting a different new battery.
Left/right identification
If you are wearing hearing aids on both ears, and
you want to make sure you are placing them cor-
rectly, you can arrange with your hearing health-
care professional to have a small identification
mark (red nameplate) on the right-ear hearing
aid.

Placing Senso on/in the ear
Insert a battery in your hearing aid. We recom-
mend that you turn off the hearing aid before
placing it on the ear. First insert the earmould in
the ear canal while holding the lower part of the
tubing. It may also be helpful to gently pull the
outer ear backwards and upwards with the oppo-
site hand.
Once the earmould has been
inserted, you place the hear-
ing aid behind the ear, so
that the hook rests comforta-
bly on the ear, close to your
head. When the hearing aid
is in its correct position, turn
on the hearing aid.

16
17
Removing Senso
First remove the hearing aid from its position be-
hind the ear. Carefully pull the earmould out of
the ear canal, while holding the lower part of the
tubing. If it is difficult, it may help to try to move
the earmould carefully from side to side while
pulling it out. It may also help to pull the outer
ear upwards and backwards with the opposite
hand.
In case of malfunction
Should your hearing aid be completely or periodi-
cally dead, try the following before consulting
your hearing healthcare professional:
• Make sure the hearing aid is switched on.
• Disconnect the tubing with earmould from
the hook of the hearing aid and check if
there is moisture in the tubing.
• Check that the earmould is not blocked by
earwax. Disconnect the tubing with ear-
mould from the hook of the hearing aid and
try to blow air through the earmould with a
small blower.
• Change the battery and make sure the new
battery is correctly inserted.
See the Troubleshooting guide p. 30-31.

Important
Please be sure to keep your hearing aid and its
accessories out of the reach of children, who might
place them in their mouths.
Also keep batteries out of children’s reach and
discard used batteries carefully.
Do not change batteries in front of children or let
them see where you keep your supply.
Never put batteries in your mouth for any reason
and never let a child obtain a battery or place it in
his or her mouth.
In case of ingestion, contact your physician imme-
diately.
The hearing aid is made of modern non-allergen-
ic materials. Still, in rare cases skin irritation can
occur. If you notice skin irritation in or around
your ear or ear canal, contact your hearing health-
care professional.
The use of hearing aids increases the risk of accu-
mulation of earwax, which can temporarily re-
duce your hearing ability. Contact your ENT doc-
tor if you suspect that a plug of earwax has accu-
mulated in your ear.
Please be aware that the use of any type of ear-
mould may involve a slightly increased risk of in-
fection in the ear canal. An infection can arise as
a result of inadequate ventilation of the ear or
scratches in the ear canal caused by the ear-
mould. Therefore, we recommend that you take
off your earmould at night to allow the ear canal
to be ventilated. Make sure that you clean and in-
spect your earmould as required. If an infection
occurs it is a good idea to clean your earmould
with a disinfecting tissue or the like. Do not un-
der any circumstances use alcohol, chlorine or
similar substances to clean your earmould.
When not in use
When your hearing aid is not in use, it should be
placed in the small case, which you can easily car-
ry in a pocket or purse.
Never expose the hearing aid to excessive heat,
such as leaving it on a window sill, near a radia-
tor or near a car window.

Audio input
Senso can be furnished with an
audio shoe. This allows direct
connection to CROS/BiCROS
systems as well as assistive lis-
tening devices such as FM equip-
ment, hand-held microphones,
TVs, and cassette players.
Connecting the audio shoe
Before connecting, the little cov-
er on the side of the hearing aid
must be replaced with the cover
which has one hole.
A Europlug is used for connec-
tion. Insert the plug into the
socket on the base of the audio
shoe. Please note that the plug will only connect
one way, as one of the three pins is thicker than
the other two.
Make sure that the M-MT-T switch is set to M
(microphone).
Slide the audio shoe
onto the hearing aid,
as shown. Press the
shoe gently onto the
aid until you feel a
click.
If the audio shoe is equipped with a
switch, you have the choice of lis-
tening to audio input only (MIC
OFF) or to audio input plus hear-
ing aid microphone (MIC ON).
Remove the audio shoe by gently
sliding it off and pulling it away
from the hearing aid, as shown.

22
23
CROS/BiCROS with
an audio shoe and a
CROS dummy
The audio shoe can also
be used together with
CROS/BiCROS. For this,
a CROS dummy and a
cord with a Europlug at
both ends are used.
Important: If the hearing aid is
connected to equipment which is
connected to the electrical mains,
this equipment must meet the
safety requirements stated in the
international standard IEC 65.
Do not connect the hearing aid to sockets
that are labelled with one or more of the
following symbols:
Caring for your hearing aid
With proper care, your hearing aid will give you
years of reliable service. Here are some things
you can do to prolong the life of your aid:
Treat your hearing aid as the valuable object it is:
with care!
When not in use, keep it in its case in a cool, dry
location where it cannot be reached by children or
pets.
Never expose it to extreme temperatures or high
humidity.
Do not wear your aid in the shower or swimming,
or when using a hair dryer, hair spray, or other
sprays.

24
25
Do not wear your hearing aid during x-ray, MR
scans, CT scans, short-wave diathermy, or simi-
lar radiation treatments.
Some types of radiation can damage your hearing
aid. Other types of radiation from, for example,
burglar alarms, room surveillance equipment,
and cellular telephones, are weaker and will not
damage your hearing aid.
Widex hearing aids are not certified for use in
mines or other areas with explosive gases.
Switch your hearing aid off when it is not in use.
Should you not use it for a day or more, take out
the battery to avoid battery leakage. Always in-
sert the battery as described on page 10. If you
feel the battery needs to be forced into the battery
drawer, then check to see if it’s upside down.
Never try to open or repair
the hearing aid yourself
Accessories
The following accessories are available for your
hearing aid:
A. Battery magnet to facilitate insertion of the
battery into the battery drawer.
B. Wax removing tool for cleaning the relief
vent opening.
C. Soft cloth for drying and cleaning the hear-
ing aid.
A. B. C.

The hearing aid
Never wash your hearing
aid with water, cleaning
solutions or other liquids.
Instead, clean your hear-
ing aid with a dry soft
cloth after use.
When the hearing aid is not in use, it is a good
idea to leave the battery drawer open, so as to
ventilate the aid and allow it to dry.
The earmould
Make sure your ear-
mould is clean and free
of earwax and moisture.
If it is plugged, clear the
opening with the wax
removing tool.
If this is not sufficient, discon-
nect the plastic tube from the
hook of the hearing aid and
wash the earmould in luke-
warm water and a mild dish-
washing soap. Rinse in cold
water. Allow the earmould to
dry overnight.

28
29
If there is still moisture
in the earmould or tube,
use a syringe or a small
blower to blow it dry. Do
not use alcohol to clean
your earmould!
If your earmould tubing becomes stiff, yellow or
cracked, contact your hearing healthcare profes-
sional for a replacement.
There is only one way
Your hearing aid does not restore normal hearing,
but it will help you to hear and understand what
other people are saying – and to enjoy many other
sounds. So don’t give up. The learning process
will take time, but millions of experienced users
can testify that the results are worth the effort.
There are no tricks or short cuts by which you can
obtain immediate and full benefit from your hear-
ing aid. Only consistent and determined practice
will give you the maximum results from your
hearing aid.
It takes time getting used to “hearing” again and
to having “something” in your ear. Your ear may
even become a little sore at first, but that will
pass.
The sooner you become accustomed to wearing
the hearing aid every day and all day long, the
sooner you will succeed.
Take the time and effort. Hearing more out of life
is worth it!
