Getting started
Prior to connecting to ReSound Aventa 3:
1. ReSound devices require a battery when fitting. Make sure the
battery is fresh and that it is inserted correctly.
a. For wireless fittings, insert AirlinkTM/Airlink II in a USB slot on
the fitting PC and wait for the message that new hardware
has been found. Then open ReSound Aventa 3.
b. For wired fittings, ensure that the programming interface
(Speedlink, Hi-PRO or NOAHlink) is connected to the PC
before launching ReSound Aventa 3.
2. Launch ReSound Aventa 3. For new fittings, ReSound Aventa 3
begins in the Start screen, where the patient’s experience with
amplification can be selected. Selection of fitting interface and
connection to the hearing aids is done in the upper part of the
Start screen.
Remove the stickers from the size 13 batteries to activate them.
Wait for 2 minutes for best results. Click “Connect” in the center of
the top ribbon of the ReSound Aventa 3 Start screen.
Insert the battery and close the battery door of each hearing
instrument to be programmed, and then click “Connect.”

A window will appear showing the status of the connection, and will
alert you to recommendations for venting. Choose receiver and vent
configuration as needed. Click “Continue.”
If you have selected “Experienced linear” in the Pre-Fit screen
and you are fitting a UP receiver, you will be prompted to choose
an amplification mode. Linear mode provides the same gain for
all input levels and has only one input level control. Semi linear
provides a lower compression ratio than WDRC.

At this point, you may pair ReSound UniteTM accessories by clicking
“Unite Accessories”, or proceed to the fitting by clicking “Continue”.
In this guide, “Continue” is selected.
If fitting a UP receiver, a progress window will alert you to the
capability of the hearing instrument to exceed 132 dB SPL. Click
“Continue.”
Next, a window will appear to prompt calibrating DFS UltraTM II.
Click “Calibrate” to begin the calibration procedure. The progress of
the calibration will be shown. Click “Continue” after calibration is
completed.

Gain adjustment
When the Fit screen is displayed, the hearing instrument gains and
MPOs can be adjusted, and advanced features can be accessed.
Fine-tune the hearing instruments
Safe fitting on

Maximum stable gain and Safe Fitting
Once DFS UltraTM II is calibrated, the Fit screen automatically opens
with two shaded grey areas visible on the graph (in most cases).
The darker grey shaded area indicates unavailable gain while the
light grey indicates added maximum stable gain provided by DFS
UltraTM II.
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 DFS UltraTM II, there will only be one shaded area which
indicates the full-on gain of the particular hearing instrument.
1510_LN2_FittingGuide_MK604304_rB_8.5x11.indd 6 10/16/15 9:55 AM

Program management
The Program tabs are located between the graph and the gain
handles. This is where programs can be reordered, compared,
recalculated, autorelated, copied, pasted, added or removed.
Advanced features
Feature settings are accessed by clicking “Advanced Features”
in the “Tools” menu on the left side of the screen. These feature
settings apply to the currently selected program.
Directionality
Binaural DirectionalityTM II uses ReSound’s 2.4 GHz wireless
technology to allow the hearing instruments to work together,
dynamically selecting the best microphone response for the
listening environment. The result may be a bilateral omnidirectional,
bilateral directional or an asymmetric omnidirectional and directional
response, depending on the analysis of speech and noise detectors
from both hearing instruments. This provides the user with the
optimal combination of speech understanding in noise plus a more
natural sense of surroundings - even in the most difficult listening
situations.
Natural DirectionalityTM II: The Focus and Monitor ears are
prescribed based on the audiogram and any speech audiometry
data that may be available, but this selection can be reversed
through ReSound Aventa®.
Spatial SenseTM mimics the human ear’s natural response to
sound, which preserves spatial cues and helps with the localization
of sound sources.
SoftSwitchingTM seamlessly enables and disables AutoScope/
MultiScope Adaptive Directionality™depending on the listening
environment. The response can be either omnidirectional or
directional, based on the signal-to-noise ratio and direction of
speech in the listening situation.
AutoScope Adaptive DirectionalityTM enables the beam width
to automatically widen or narrow depending on the acoustic
surroundings.
If ear-to-ear is activated, SoftSwitching will ensure that the
microphone responses on both instruments are synchronized.
1510_LN2_FittingGuide_MK604304_rB_8.5x11.indd 7 10/16/15 9:55 AM

Directional Mix
The Directional Mix setting determines the degree of directionality
in the output of the hearing instrument(s). Directional Mix applies
omnidirectional processing below a crossover frequency and
directional processing above that frequency. The default setting is
prescribed depending on the hearing instrument model selected
and the degree of low-frequency hearing loss.
DFS UltraTM II
The “Mild” settings are most appropriate for speech and everyday
inputs, “Moderate”, and “Strong” are good for feedback-critical
situations like phone use. The “Music Mode” is designed for use in
a “Music” program.
Auto DFS allows for a standard setting of DFS to be applied without
calibration. If DFS has already been calibrated, the Auto DFS
options (“On” and “Off”) are automatically grayed out.
Sound ShaperTM
Sound Shaper is ReSound’s proportional frequency compression
system. Its default setting is “Off.” The recommended setting,
based on the audiogram, is in bold typeface when the menu
options are pulled down.
Low Frequency Boost
If fitting a UP receiver, low Frequency Boost can be applied for
users desiring more gain from 250-1000 Hz. “Low”, “Medium” and
“High” settings will be achieved unless the maximal gain has already
been met at these frequencies.
NoiseTrackerTM II
In NoiseTrackerTM II, the degree of noise reduction applied at any
moment depends on the listening environment. Per environment
noise reduction levels can be customized via Environmental
OptimizerTM II.
WindGuardTM
WindGuardTM uses signal processing to reduce wind noise, and is
available in dual microphone devices.

ReSound Aventa®3.9 includes three input level controls at 50,
65 and 80 dB SPL. This allows for greater flexibility for fine-tuning
gains, By default, ReSound Aventa®calculates the gain settings
for the particular audiogram using the Audiogram+ fitting rationale.
Other fitting prescriptions can be selected from the “Fitting” menu.
To fine-tune a program, adjust the gain manually by using the gain
handles or by using the ReSound Aventa®Guide, where fine-tuning
solutions to patient complaints can be automatically applied.
Once fine-tuning is complete, the relative gain changes can be
applied to any or all other programs by clicking the “Autorelate”
button in the program handling tool bar beneath the program tabs.
Select which programs to autorelate to by checking the boxes. You
may choose whether to apply changes made to MPO or Sound
Shaper or compression mode for each program.
Physical properties
Dome type and vent configuration can be changed in Physical
Properties. Selections in this screen affect the display of gains 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 expected real ear response. An option
to (re)calibrate DFS is provided in case the change entered in
Physical Properties accompanies a physical hardware change of
the vent/tube/dome on the hearing instrument.
Environmental OptimizerTM II
Environmental OptimizerTM II allows specific gain and NoiseTrackerTM
II adjustments for a possible combination of seven different
environments, ensuring the user receives optimal gain and noise
reduction settings as the acoustic environment changes. If Ear-
to-Ear Communication is enabled, the hearing instruments will
optimize and synchronize the Environmental Optimizer II gain and
noise reduction settings for a binaural fitting (Binaural Environmental
OptimizerTM II).

Ear-to-Ear Communication
ReSound LiNX2supports ear-to-ear communication. The master
switch to disable/enable this functionality can be found in the main
menu under “Instrument.” The “Ear-to-Ear Communication” window
keeps a continual record of the enabled Ear-to-Ear features.
Tinnitus Sound Generator
The default setting for Tinnitus Sound Generator (TSG) is off. When
TSG is in the “Standard” mode, TSG options such as noise type,
level, modulation and modulation speed can be changed; when
TSG is in the “Nature Sounds” mode, only sound level can be
changed.
Synchronized Acceptance Manager
Synchronized Acceptance Manager allows for gradual gain
increases from current gains to final gains over a specified amount
of time. Synchronization of this feature is recommended in case of
a loss of one hearing instrument during the acclimatization time, as
this will prevent the remaining hearing instrument from progressing
more than 10% past the progression of the lost hearing instrument,
in the event it is found. Once activated, the Acceptance Manager
progress will appear on the Fit screen. Final gain levels will appear
as dotted lines. To set a final level different than current gain
prescription, ensure the box above the gain handles indicates “End
Gains (B).” Select the gain handles desired and fine tune the gains
to the desired levels.
Beeps and Volume Control
The “Beeps and Volume Control” window has two tabs: Standard
Beeps and Manual Controls. In the Standard Beeps tab, all the
acoustic indicators can be demonstrated, changed, added and
removed. Low or high frequency beeps can also be selected. The
Manual Controls tab contains options such as customizing push
button function, enabling and disabling the program button and
adjusting the volume control range.

Manage accessories
The functionality for managing connectivity to Bluetooth®Smart
devices and ReSound UniteTM accessories can be accessed both
from the Pre-Fit and the Fit screens.
To pair ReSound Unite accessories with the hearing instruments,
click “Add” and follow the instructions on the screen to put the
selected accessory in pairing mode. Accessory pairing can also be
achieved outside of ReSound Aventa®, with the hearing instruments
and the accessory alone.
Bluetooth Smart-enabled devices
Up to 5 Bluetooth Smart-enabled devices can be paired to the
hearing instruments, but pairing must occur outside of ReSound
Aventa.
Saving and completing the fitting
Once the fitting is complete, click “Save” at the bottom right
of the Fit or Summary screens. Once the data is saved to the
instruments and to the database, it is safe to disconnect the hearing
instrument(s).
Summary screen
The Summary screen allows the clinician to print information for
the patient, a third party, or for chart notes. Notes can be entered,
saved and printed as needed.
