Connecting to the hearing instrument(s)
Select the appropriate patient experience level in the Patient
information box. This will ensure the best starting gain settings
for the patient.
Choose the appropriate programming interface in the "Connect
using" drop-down menu in the Aventa 3.3 Start screen. For
ReSound Vea, this is either Speedlink, Hi-PRO or NOAHlink.
For BTE fittings, slide down the cover on the inside of the
hearing instrument and attach the programming adaptor II.
Connect the hearing instrument(s) to the Speedlink, Hi-PRO or
NOAHlink with the CS44 cable. For custom fitting, use 3-pin
flex strip CS63 and programming cable CS63.
Click "Connect" in the upper
right corner of the Aventa 3
Start screen.
AutoFit
For fast fitting click "AutoFit"
in the Start screen. When
AutoFit has been selected
the instrument(s) will be
connected and go through
4 steps: Fit, Calibrate DFS,
AutoREM and Save. Any step can be cancelled if necessary.
When AutoFit has completed you can choose either to "Go to
Fit Screen" and do fine-tuning or simply "Exit Aventa".
Reconfigure
Vea BTE and mini BTE models can be fit open or closed. To
change from open to closed, or vice versa, the instrument(s)
must be reconfigured. This is done in the Pre-Fit screen. In the
middle of the screen there is a button called "Reconfigure". Click
this button and follow the instructions to change instruments to
the desired configuration.
If a closed model is being changed to an open model remember
to change the hook to a thin tube adaptor.
Turn the hook 90 degrees and pull. Insert the thin tube adaptor
completely in a 90 degree angle and turn it upright.

DFS calibration
Once the hearing instrument(s) are connected, an auto-prompt
for DFS calibration will appear. It is strongly recommended to
always run the calibration at the start of a new fitting, or if venting
(including dome changes or earmold changes) are made. This
is because any such changes affect the feedback path and thus
the performance of Dual Stabilizer II DFS
that a brief buzzing sound will be presented to each ear, and
that they should sit quietly. Click "Yes" to begin the calibration.
Maximum stable gain and Safe Fitting
Select programming
Once the Dual Stabilizer II DFS
TM
is calibrated, the Fit screen
interface and click
automatically opens with two shaded grey areas visible on the
'Connect'
graph (applied to most cases). The darker grey shaded area
indicates unavailable gain while the light grey indicates added
maximum stable gain provided by Dual Stabilizer II DFS
If Safe Fitting is enabled, gain settings will be locked at the dark
grey border. Safe Fitting can be turned off and on in the Fitting
menu or set as a user preference. Note that if you have not
calibrated Dual Stabilizer II DFS
TM
, there will only be one shaded
area which indicates the full on gain of the particular hearing
instrument(s).
Fine-tuning
Click AutoFit
By default, Aventa calculates the gain settings for the particular
audiogram using the Audiogram+ fitting rationale. To fine-tune a
program, adjust the gain manually by using the gain matrix or by
using the Aventa Guide where solutions to patient complaints
can be automatically applied.
Once fine-tuning is complete you can copy the relative gain
changes to any other program in your fitting. This can be done
by clicking the "Autorelate" button in the tool bar beneath the
program tabs. Gain adjustments can be autorelated to all or to
selected programs. Select which programs to autorelate to by
checking off the boxes.
New in Aventa 3.3 is the ability to recalculate current program
or all programs.
Choose "Go to Fit
Screen" or "Exit
Aventa"

Program management
The program tabs are located between the graph and the gain

removed.
PhoneNow has its own dedicated program tab to the right of
the 3 regular programs. PhoneNow will be activated by use
of the PhoneNow magnet. PhoneNow is turned 'On' in the
PhoneNow program.
Tools
Advanced Features
Feature settings including Expansion, Dual Stabilizer II DFS

TM
TM
are accessed by clicking "Advanced Features" in the "Tools"
menu. These settings apply to the currently selected program,
and are summarized in the "Features Summary" below the
"Tools" menu.
Physical properties
Physical properties can also be found in "Tools" on the Fit
screen.
Dome and tube selection, and vent configuration can be made
here. Apart from record-keeping for the fitting, selections made
in this screen affect the display in the Fit screen. For example,
when venting is changed, the amount of roll-off in the low
frequencies will be adjusted to show how this physical change
affects the real ear response.
Beeps and volume Control
Once fine-tuning is complete, click on "Beeps and Volume
Control" in the tool set on the Fit screen. A screen will pop
up where all the acoustic indicators can be demonstrated,
changed, added and removed. It is possible to choose a low
frequency beep set or a high frequency beep set.
It is also where volume control changes can be made.
Programming
Once the fitting is complete and all the necessary adjustments
are made, click "Save" at the bottom right of the Fit screen.
Once the data is saved to the instrument(s) and to the database
(Noah) a green confirmation box will display next to the "Save"
button.
At this time it is safe to disconnect the instrument(s). A second
option at this time is to go to the Summary screen. If any
changes are made the confirmation will disappear and it will be
necessary to re-save the data before disconnecting.
Summary
The summary page allows the clinician to print information for
the client, a third party, or clinic notes for a chart. Notes can be
made and saved and then printed as needed.
