light up permanently depending on configuration.
Turning your instruments OFF
When turning your instrument OFF you can use one of
the following options:
1) Turn the volume control down until it clicks.
2) Set the function switch to OFF if it has been
programmed with an OFF position.

Inserting your hearing instrument
• Your hearing instruments
may have a right/left-
identification. Red=Right,
Blue=Left
• Turn off the hearing
instrument.
• Hold the plastic tube as
shown.
• Place the tip of the earmold
in your ear canal, twisting
slightly, making sure that
the top part of the earmold
(A) is pushed behind and
under the fold (B) of your
ear.
• Gently pull down your
earlobe and press the
earmold in the direction
of the ear canal.
• With the earmold correctly
positioned, slide the hearing
instrument over the top of your
ear to rest behind it.
• Turn on the hearing instrument
and adjust the volume control
until you hear the beeps
indicating the preferred
volume control level. This
feature is optional and may be
disengaged by your hearing
care professional.

Your hearing aid has a 3-position switch for switching
between different programs.
• When you switch between different programs, your
hearing instrument will beep.
• Operate the function switch to change programs.
The number of beeps will indicate which program
you are using if beeps are enabled.
Your hearing instrument can have up to three different
programs.
Please note that one program may be programmed as
an off position. (Optional)
One beep, when you switch to program 1

Telecoil
The telecoil is meant for telephone conversations and
for loop systems in e.g. theatres, churches or lecture
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.
Volume Control
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 find 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.
If you turn the wheel below (1) you can feel a click
and the instrument will turn off.
Your Volume Control can be disabled if you do
not wish to use it. This will also disable the off
functionality in the Volume Control.

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:
• 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.
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.
• 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.

Extended Communication
The benefit from your hearing instruments can be
increased in difficult 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.
Tamper-resistant battery door
(optional)
This option is strongly recommended for infants, small
children, and people with learning difficulties.
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.

Ear-level/wireless FM systems
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.
Dedicated receiver for Lexis FM
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 profile compared to a universal receiver.
Consult your Hearing Care Professional for advice and
purchase information about ear-level/wireless FM
systems.

DirectAudio 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 specified 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.
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 battery-
operated 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.
