Your Widex Senso hearing aid is a very intricate,
high precision electronic unit. It has been carefully
designed to withstand years of wear, under the var-
ying conditions the typical user finds themselves in
each day. However, your hearing aid may be damaged
if exposed to extreme conditions, severe blows, or gen-
eral neglect.
To get full satisfaction from the quality and the per-
formance 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 according
to your expectations.
We hope you will be pleased with
your new Widex hearing aid!
A. Volume control
B. Telecoil (M-MT-T switch)
C. On/off switch and
battery drawer

5
Turning the hearing aid on
and off
The battery drawer also functions
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 illustrated.
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.

6
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 adjusting
the volume – it happens quite automatically.

7
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 slight-
ly raise the volume of the auto-
matic setting.
Press the lever downwards to slightly lower the vol-
ume of the automatic setting.
When you raise the volume, you will hear a beep-tone
for each step the volume is raised. When the maxi-
mum adjustment level is reached, a steady tone will
sound until you release the lever.
When you lower the volume, you will hear a deeper
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 pro-
longed use at uncomfortably high sound pressure lev-
els – it might damage your hearing.
For further information, consult your hearing health-
care professional.

Telecoil (M-MT-T switch)
“M” (microphone): For normal
use, the switch should be in posi-
tion “M” (microphone).
“T” (telecoil): Position “T” cuts
off the microphone and brings the
built-in telecoil into operation.
The hearing aid can then be used within any mag-
netic field or loop system without background inter-
ference.
A loop system or magnetic field device can be fitted
to a TV or radio. Some public places such as church-
es, theatres, cinemas and lecture rooms are already
equipped with a loop system.
Ask your hearing healthcare professional for more in-
formation.

9
Note: The magnetic field in some telephones is inad-
equate, 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 doorbell, telephone, or
other persons speaking).

10
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 oth-
er unwanted substance as this
can block the battery airholes.
Push the nail grip downwards to
swing open the battery drawer.
The nail grip is located on the op-
posite side of the on/off switch at
the bottom of the hearing aid.
The battery must be placed with
the plus (+) sign visible, in ac-
cordance with the plus (+) sign on
the battery drawer. If the battery
drawer does not close easily, the
battery is incorrectly 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.

11
Exhausted batteries: If you hear four rapid beep-
tones while wearing your hearing aid, it is an indica-
tion that you should exchange the battery 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 another.
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.

12
Recommended energy source:
Zinc Air battery type 675
This hearing aid uses an environmentally friendly,
type 675 Zinc Air battery, which provides a long life-
time 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 inserted, the bat-
tery will start functioning after a few seconds. Oper-
ate 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 envi-
ronments 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 battery, try
inserting a different new battery.

13
Left/right identification
If you are wearing hearing aids on both ears, and you
want to make sure you are placing them correctly,
you can arrange with your hearing healthcare profes-
sional to have a small identification mark (red name-
plate) on the right-ear hearing aid.

14
Placing Senso on/in the ear
Insert a battery in your hearing aid. We recommend
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 opposite hand.

15
Once the earmould has been
inserted, you place the hearing
aid behind the ear, so that the
hook rests comfortably on the
ear, close to your head. When
the hearing aid is in its cor-
rect position, turn on the hear-
ing aid.

16
Removing Senso
First remove the hearing aid from its position behind
the ear. Carefully pull the earmould out of the ear ca-
nal, 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 back-
wards with the opposite hand.

17
In case of malfunction
Should your hearing aid be completely or periodical-
ly dead, try the following before consulting your hear-
ing 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 earmould
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 acces-
sories out of the reach of children, who might place
them in their mouths.
Also keep batteries out of children’s reach and dis-
card 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 immedi-
ately.
The hearing aid is made of modern non-allergenic ma-
terials. Still, in rare cases skin irritation can occur. If
you notice skin irritation in or around your ear or ear
canal, contact your hearing healthcare professional.
The use of hearing aids increases the risk of accumu-
lation of earwax, which can temporarily reduce your
hearing ability. Contact your ENT doctor if you sus-
pect that a plug of earwax has accumulated in your
ear.

19
Please be aware that the use of any type of earmould
may involve a slightly increased risk of infection in
the ear canal. An infection can arise as a result of in-
adequate ventilation of the ear or scratches in the ear
canal caused by the earmould. Therefore, we recom-
mend that you take off your earmould at night to al-
low the ear canal to be ventilated. Make sure that
you clean and inspect your earmould as required. If
an infection occurs it is a good idea to clean your ear-
mould with a disinfecting tissue or the like. Do not
under any circumstances use alcohol, chlorine or sim-
ilar 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 carry
in a pocket or purse.
Never expose the hearing aid to excessive heat, such
as leaving it on a window sill, near a radiator or near
a car window.

Audio input
Senso can be furnished with an
audio shoe. This allows direct con-
nection to CROS/BiCROS systems
as well as assistive listening devic-
es such as FM equipment, hand-
held microphones, TVs, and cas-
sette players.
Connecting the audio shoe
Before connecting, the little cover
on the side of the hearing aid must
be replaced with the cover which
has one hole.
A Europlug is used for connection.
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 (mi-
crophone).
