rooms.

The telecoil is activated by operating the function
switch. When activated you will hear a certain number
of beeps.

Your telecoil can be disabled if you do not wish to use
it. This will also disable any use of direct audio input
(DAI) and FM functionality.

This wheel allows you to adjust the sound level in
different listening situations. The preferred volume
control level can be indicated by three beeps. This
level has been programmed according to your
preferences. Consult your Hearing Care Professional
if you fi nd this level too loud or too weak in most
situations.

Turning up the control increases the volume.
Maximum setting (4) gives you the loudest sound.

Turning down the control decreases the volume.
Minimum setting (1) gives you the quietest sound.

Battery Replacement

A worn-out battery should be removed immediately.
When battery power is low, you will hear a series
of two beeps. If the status light is programmed to
be steady on, it will turn off. This indicates that it
is time to change the battery. It is not an indication
of malfunction. To replace the battery, follow these
instructions:

Any moisture on the battery surface should be wiped
off before use. When you change batteries, it may take
a couple of minutes before the new battery works with
full effect.

Disposal:

• Check with your Hearing Care Professional about
arrangements for battery disposal. There may be
a system for disposing of them.

• Open the battery door
by pushing back the
raised edge and remove
the old battery.

• Remove the sticky label
from the + side of the
new battery

• Insert the new battery (size 675, preferably
dedicated super power battery) so that its + sign
faces the + sign printed on the top of the battery
door.

• The battery door should close easily. If you feel
any resistance it could be that you have placed
the battery incorrectly. Reinsert the battery and try
again.

12 13

• Never try to charge non-rechargeable batteries.

• Never dispose of batteries by burning them. There
is a risk that they will explode and cause serious
injury.

Tamper-resistant battery door
(optional)

This option is strongly recommended for infants, small
children, and people with learning diffi culties.

Instructions: To remove the battery, open the battery
door. (If a DAI shoe is mounted, the shoe has to be
removed). Insert the end of a ballpoint pen (or similar
type of object like a miniature screwdriver or paperclip
point) into the small recess in the corner. Push the
battery with the ballpoint until the battery is released.

Important: Do not force the battery door beyond
its fully open position. Insert the battery correctly.
Excessive strain can deform the battery door,
which will reduce its function and tamper resistant
effectiveness.

Extended Communication

The benefi t from your hearing instruments can be
increased in diffi cult listening situations. Your hearing
instruments are compatible with ear level FM systems,
which can allow you to hear a person talking at a
distance without interference from background noise.
You can also access interference-free audio signals via
the Direct Audio Input (DAI).

Mounting of accessories

Note: Your FM receiver or Direct Audio Input
accessories connect through the appropriate audio
input shoe, which is securely locked into position into
the battery door.

Ear-level/wireless FM systems

Dedicated receiver for Lexis FM

When using an ear-level FM system, set your program
switch to your telecoil program allowing you to hear
the external signal. Please note that your instrument
may be set up with one or more telecoil programs that
do not allow you to listen to the external signal. Your
Hearing Care Professional can change this if desired.

Consult your Hearing Care Professional for advice and
purchase information about ear-level/wireless FM
systems.

Users of the Lexis FM system can choose the dedicated
LE-7 receiver for Sumo DM, which conveniently
eliminates the need for an adaptor shoe and provides a
smaller profi le compared to a universal receiver.

Consult your Hearing Care Professional for advice and
purchase information about ear-level/wireless FM
systems.

16 17

Direct Audio Input (DAI)

DAI provides access
to interference-free
audio signals from
external sources (such
as radio, TV, PC Audio
output, personal CD
players, etc). The signal
is received directly
into your hearing
instruments by using
a specifi ed cord and
coupling shoe.

When using a Direct Audio Input device, set your
program switch to your telecoil program allowing
you to hear the external signal. Please note that your
instrument may be set up with one or more telecoil
programs that do not allow you to listen to the external
signal. Your Hearing Care Professional can change this
if desired.

Consult your Hearing Care Professional for advice and
purchase information about DAI coupling shoe and
cords.

Warnings

Hearing instruments and batteries can be dangerous if
swallowed or improperly used. Such actions can result in
severe injury, permanent hearing loss or even be fatal.

You should fully familiarize yourself with the following
general warnings and the full contents of this booklet before
using your hearing instrument.

• Hearing instruments should be used only as directed and
adjusted by your trained Hearing Specialist. Misuse can
result in sudden and permanent hearing loss.

• Hearing instruments, their parts and batteries are not toys
and should be kept out of reach of anyone who might
swallow these items or otherwise cause themselves injury.

• Never change the battery of the hearing instrument in front
of infants, small children and people with learning diffi­culties.

• Discard batteries carefully in a place where they cannot be
reached by infants, small children or people with learning
difficulties.

• Never put your hearing instrument or batteries in your
mouth for any reason, as they are slippery and could be
swallowed.

• Never allow others to wear your hearing instrument, as
it could be misused and permanently damage another’s
hearing.

• Hearing instruments may stop functioning, for instance if the
battery goes dead. You should be aware of this possibility,
in particular when you are in traffic or otherwise depend on
warning sounds.

If a battery or hearing instrument is swallowed, see a doctor
immediately and call the National Poison Center,
collect [phone].

Warning to hearing instrument dispensers

A hearing instrument dispenser should advise a prospective
hearing instrument user to consult immediately with a
licensed physician (preferably an ear specialist) before
dispensing a hearing instrument. If the hearing instrument
dispenser determines through inquiry, actual observation,
or review of any other available information concerning the
prospective user, that the prospective user has any of the
following conditions:
(i) Visible congenital or traumatic deformity of the ear.
(ii) History of active drainage from the ear within the

previous 90 days.

(iii) History of sudden or rapidly progressive hearing loss

within the previous 90 days.
(iv) Acute or chronic dizziness.
(v) Unilateral hearing loss of sudden or recent onset within

the previous 90 days.
(vi) Audiometric air-bone gap equal to or greater than 15

decibels at 500 Hertz (Hz), 1,000 Hz, and 2,000 Hz.
(vii) Visible evidence of significant cerumen accumulation or

aforeign body in the ear canal.
(viii) Pain or discomfort in the ear.

Special care should be exercised in selecting and fitting a
hearing instrument whose maximum sound pressure capability
exceeds 132 dB SPL as there may be risk of impairing the
remaining hearing of the hearing instrument user.

Important notice for prospective hearing instrument
users

Good health practice requires that a person with a hearing
loss have a medical evaluation by a licensed physician
(preferably a physician who specializes in diseases of the ear)
before purchasing a hearing instrument. Licensed physicians
who specialize in diseases of the ear are often referred to as
Otolaryngologists, Otologists or Otorhinolaryngologists. The
purpose of medical evaluation is to ensure that all medically

treatable conditions that may affect hearing are identified
and treated before the hearing instrument is purchased.
Following the medical evaluation, the physician will give
you a written statement that states that your hearing loss has
been medically evaluated and that you may be considered a
candidate for a hearing instrument.

The physician will refer you to an audiologist or a hearing
instrument dispenser, as appropriate, for a hearing
instrument evaluation.

The audiologist or hearing instrument dispenser will
conduct a hearing instrument evaluation to assess your
ability to hear with and without a hearing instrument.
The hearing instrument evaluation will enable the
audiologist or dispenser to select and fit a hearing
instrument to your individual needs. If you have reserva­tions about your ability to adapt to amplification, you
should inquire about the availability of a trial, rental
or purchase-option program. Many hearing instrument
dispensers now offer programs that permit you to wear a
hearing instrument for a period of time for a nominal fee,
after which you may decide if you want to purchase the
hearing instrument.

Federal law limits the sale of hearing instruments to those
individuals who have obtained a medical evaluation from
a licensed physician. Federal law permits a fully informed
adult to sign a waiver statement declining the medical
evaluation for religious or personal beliefs that preclude
consultation with a physician. The exercise of such a waiver
is not in your best health interest and its use is strongly
discouraged. A hearing aid will not restore normal hearing
and will not prevent or improve a hearing impairment
resulting from organic cinditions. A hearing aid is only part
of hearing rehabilitation and may need to be supplemented
by auditory training and lip reading.

Possible side effects

The hearing aid or earmold is a custom-made product. If
you are experiencing discomfort, see your audiologist or
hearing instrument dispenser immediately for modification
of the hearing instrument or earmold at the point of
irritation.A hearing instrument or earmold may cause an
accelerated accumulation of cerumen (earwax). Also in
rare cases, the otherwise non-allergenic material may cause
a discharge from the ear, allergic reac-tion, or any other
unusual condition. Please seek immediate consultation with
a physician if these conditions occur.

Children with hearing loss

In addition to seeing a physician for medical evaluation,
a child with a hearing loss should be directed to an
audiologist for evaluation and rehabilitation, since hearing
loss may cause problems in language development,
educational and social growth of a child. An audiologist
is qualified by training and experience to assist in the
evaluation and rehabilitation of a child with a hearing loss.
If the user is an infant, small child or person of mental
incapacity, it is recommended that the hearing instrument
be modified with a tamper-resistant battery compartment.

Adjustment of DAI

Note: Your hearing care professional can adjust your
DAI shoe according to the application
and level of input signal.

Step 1

Adjustment according to the
equipment the instrument is to
be connected to:

Hi setting: Plugged-in (AC)
equipment such as radio,
TV, computers, and battery­operated devices using 4.5
volts or greater; body-worn FM
equipment.

Lo setting: Battery operated
equipment( <4.5 volts) such as
personal stereo/MP3 players.

Step 2

Adjust the input level control to
a comfortable level.

IMPORTANT: If you are using
DAI connected to equipment
that is plugged into an electrical
outlet (TV, computer) the DAI
cord should be disconnected
from the hearing aid during an
electrical (lightning) storm.

Audible and visible status indicators

Table of functions:

Your instrument has two means of status indication, the audible
beeps and a visual status indicator (LED). The function of
these status indicators can be confi gured by your Hearing Care
Professional. In the table below you fi nd an overview of the

Daily care of your hearing
instruments

When handling a hearing instrument, hold it over a
soft surface to avoid damage if dropped.

Before retiring for the evening:

• Make sure that there is no ear wax in any of the
earmold openings since it may reduce the hearing
instruments’ effi ciency.

• Open the battery compartments to allow air to
circulate.

Cleaning your earmolds

The earmolds should be washed regularly:

• Disconnect the earmold
and tubing from the
hearing instrument.

• Rinse with water.

• Dry the earmold.

• Any water drops inside the
earmold or tubing should
be blown out. A special
device for this purpose (an
earmold blower) is
available from your Hearing
Care Professional.

• Make sure the earmold and tubing are completely
dry before they are reconnected to the hearing
instruments as shown in the drawing.

• Wash the earmold in
lukewarm water using
a mild soap. Do not use
strong detergents.

The hearing instruments
themselves must never be
washed!

Left Right

Replacing the tubing

The tubing in the earmold
should be replaced when it
becomes yellow or stiff. Consult
your hearing care professional in
relation to this.

22 23

Avoiding heat, humidity and chemicals

Your hearing instruments must never be exposed to
extreme heat e.g. left inside a parked car in the sun
or dried in microwave ovens. They must never be
exposed to a lot of moisture e.g. steam baths,
showers or heavy rain.

If your hearing instruments have been exposed to
moisture or very humid conditions it may affect their
performance. Using an anti-humidity or drying kit can
help to avoid these problems and may even extend the
life of your hearing instruments. Consult your hearing
care professional for further advice. Wipe the batteries
thoroughly if moisture is present.

The chemicals in cosmetics, hairspray, hair dye,
perfume, aftershave-lotion, suntan lotion and insect
repellant can discolor and even damage your hearing
instruments. You should always remove your hearing
instruments before applying such products and allow
time for the product to dry before reinserting your
hearing instruments. If you use lotion be sure to
wipe your hands dry before inserting your hearing
instruments.

Using your hearing instruments

It takes time to adjust to a new hearing instrument.
How long this adjustment takes differs from person to
person. It will depend on a number of factors, such as
whether you have had hearing instruments before and
the degree of your hearing loss.

Seven easy steps to better hearing

1. In the quiet of your home

Try to acclimate yourself to all the new sounds you are
able to hear, including background sounds. Listen to
the many background sounds and try to identify each
sound. Keep in mind that some sounds will sound
different. You may have to learn to identify them
again. Note that in time you will become acclimated to
the sounds in your environment – if not please contact
your hearing care professional.

If using the hearing instruments cause you to feel
fatigued, remove them. Initially, you may need to wear
the hearing instruments for shorter periods of time.
You will gradually be able to increase the amount of
time you wear your hearing instruments. Eventually,
you will be able to wear your hearing instruments
comfortably all day long.

24 25

2. Conversation with another person

Sit with someone else in a quiet room. Face each other
so you can read facial expressions easily. You might
experience new speech sounds which can seem a little
disturbing in the beginning. However, after the brain
has adapted to the new speech sounds, you may hear
speech clearer.

3. Listen to radio or TV

When listening to the TV or the radio, start out by
listening to news commentators since they usually
speak clearly, then try other programs.

If you fi nd it diffi cult to listen to TV or radio, contact
your Hearing Professional for advice about assistive
listening devices. If your hearing instrument has a
telecoil program, you may benefi t from using it with an
induction loop system.

4. In group conversations

Group situations are usually accompanied by a greater
degree of background noise. Therefore, making it a
more diffi cult listening situation. In diffi cult listening
situations, focus your attention on the person you want
to hear. If you miss a word, ask the speaker to repeat it.

5. Telecoil use in church, theatre, or cinema

An increasing number of churches, theatres and public
buildings have installed induction loop systems. These
systems send out wireless sound to be received by the
telecoil in your hearing instruments. Typically, the
facility will post a sign indicating that an induction
loop system is available for use by its patrons.
Contact your Hearing Care Professional for additional
information.

6. Using the telephone

When using the telephone place the receiver 1-1.5
inches above your upper part of the ear. It may also
help to tilt the receiver. If whistling occurs, tilt or
move the receiver away slightly and try to keep it still.
If your hearing instrument has a telecoil, try switching
the instrument to the telecoil program when listening
on the telephone. Depending on your telephone this
eliminates any whistling.

Remember that the telecoil
operates by detecting
magnetic waves. Many
electrical devices e.g.
facsimile machines and
computers emit magnetic
waves. Make sure that your
telephone is placed at least
4-6 feet away from such
equipment to avoid interference.

26 27

7. Wireless and mobile phones

Your hearing instruments are designed to comply
with the most stringent Standards of International
Electromagnetic Compatibility. However, not all
mobile phones are hearing instrument compatible. The
varying degree of disturbance can be due to the nature
of your particular mobile phone.

Using your hearing instruments

The use of hearing instruments is only part of hearing
rehabilitation and may need to be supplemented by
assistive listening devices auditory training and/or
instruction in lip-reading.
