2) The volume control is turned up.

3) The function switch is set to a

microphone program.

When the instrument is turned on you will hear a series

of beeps indicating which program is active, and that

the battery is working.

The LED will ﬂash to indicate the instrument is on, or

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.

Function switch

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

Two beeps, when you switch to program 2

Three beeps, when you switch to program 3

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.
