Step 1: Select the

hearing inrument type

Overview

To meet your

client’s needs, two

diﬀerent hearing

inrument types

are available:

STF P T3 for

moderate to severe hearing loss and STF XP T3

for severe to profound hearing loss. To select the

appropriate hearing inrument type, the client’s

audiogram is needed.

Step 2: Determine and set

the sound prole

Overview

Every hearing

inrument has a

choice of sound

proles. These

are pre-congured

setups of the

hearing inrument, for typical hearing losses.

You need the client’s audiogram to determine the

suitable sound prole. With the rocker switch, you

set the correct sound prole.

Note that the rocker switch has a double function:

A short press makes the hearing inrument louder or

softer. A long press changes the sound prole.

12

Inruction with example

➊Select the sound prole table which corresponds

to the hearing inrument type you have chosen in

"Step 1: Select the hearing inrument type".

➋Mark the row for the dB-value at 0.5 kHz.

➌Mark the column for the dB-value at 2 kHz.

➍The recommended sound prole is shown

where ➋ and ➌ intersect.

To set the determined sound prole in the hearing

inruments:

> Use a ethoclip to hear the

syem sounds better.

> Insert a battery and wait for the artup-melody to

ensure that the inrument is turned on.

15

> To switch to the next sound prole, hold down the top

of the rocker switch and release it after a minimum of

10 seconds.

On release, the sound prole is changed and a

conrmation tone is played.

Note that the factory setting is sound prole 1.

> To switch to the previous sound prole, proceed as

described above, but hold down the bottom of the

rocker switch.

If you turn oﬀ the hearing inrument immediately

after changing the sound prole, the sound prole

change may not be saved. Wait 5 seconds before

turning the hearing inrument oﬀ.

16

Step 3: Select ear piece and

tube length

Overview

Select the ear piece,

cut the tube and

assemble the

hearing inrument.

Inruction

> Select the ear piece that suits the client’s ear canal

size and assemble it with adapter and tube.

Start with the bigger ear piece.

17

CAUTION

Risk of injury!

> Make sure your client always wears the tube

with an ear piece.

> Make sure that the ear piece is completely

attached.

> If you provide cuom-made

ear pieces, we recommend using

them with sound prole 4 for

STF P T3 and with sound proles

2, 3 or 4 for STF XP T3.

> Turn oﬀ the hearing inrument and place the hearing

inrument on the client’s ear.

18

> Insert the ear piece in the client's ear and measure the

correct tube length. Mark it with a pen before cutting.

At a safe diance to the client, cut the tube. Attach the

tube to the hearing inrument.

> Insert the hearing inrument in the client’s ear and

turn it on.

Step 4: Te

Overview

Try diﬀerent volume levels or, if necessary,

change the sound prole.

Note that the rocker switch has a

double function: A short press makes

the hearing inrument louder or softer.

A long press changes the sound prole.

Inruction

The target is to ensure that volume and sound of the

hearing inrument is to the requirements of the client.

- Explain client how to adju the volume with the

rocker switch.

- Speak to the client (normal loudness) and let the

client increase the inruments' volume to a

comfortable level.

20

If the client needs more gain:

> Brieﬂy press the top of the rocker

switch to increase the volume.

Repeat as necessary.

> If the client ill requires more

gain, switch to the next sound

prole: Hold down the top of the

rocker switch and release it after a

minimum of 10 seconds. Refer to

section "Set the sound prole".

If the highe sound prole is ill too soft:

> Select STF XP T3.

> Or, if you have already selected STF XP T3, the

STF T3 series of hearing inruments may not be

suitable .
