A&M STF P T3, STF XP T3 User guide

  • Hello! I'm your chat assistant. I've read through the A&M Fitting Guide for STF XP T3 and STF P T3 hearing instruments. This guide provides step-by-step instructions on selecting the right hearing aid type, setting up sound profiles, and ensuring proper fitting. I'm here to answer your questions about any aspect of this guide or these instruments.
  • What are the two types of hearing instruments described in this guide?
    How do I change the sound profile on the hearing instrument?
    What do I need to determine the correct sound profile?

 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.

Inruction with example

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.

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.

 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  .
