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), receiver, or earmold changes are made. This is
because any such changes affect the feedback path and thus the
performance of DFS Ultra™ II. Counsel patients 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
Once DFS Ultra™ 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
Ultra™ 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 Ultra™ II, there will only be one shaded area which
indicates the full-on gain of the particular hearing instrument(s).

Program management
The Program tabs are located between the graph and the gain
handles. This is where programs can be changed, compared,
recalculated, autorelated, copied, added or removed. To the right of
the 4 standard programs are the PhoneNow program tab and the
wireless accessory program tabs (if applicable).
Binaural Directionality™
With Binaural Directionality, the hearing instruments work together
to dynamically select the best directional response for any
listening environment. This provides the user with the best speech
understanding in noise plus a more natural sense of surroundings -
even in the most difficult listening situations.
It is available as a program option in dual-microphone ReSound
Verso 9 BTEs as well as RIEs with wireless capabilities. Using
ReSound's 2.4 GHz wireless technology, the microphone modes
between both hearing instruments are coordinated for an optimal
binaural response. The result may be a bilateral omnidirectional,
bilateral directional or a bilateral omnidirectional and directional
response, depending on the analysis of speech and noise detectors
from both hearing instruments.
Natural Directionality™ II
Natural Directionality™ II can be selected as a program in dual-
microphone ReSound Verso models, or when device-to-device
communication is disabled in wireless Verso 9 BTE and RIE.
When this is done, choices for the Focus (fixed directional) and
Monitor (omnidirectional) ears will appear in the Advanced Features
screen. 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 by the clinician.
Binaural Directionality enables the hearing instruments to dynamically adjust microphone settings
and choose the optimal directional pattern to suit any environment. This provides users with the
information they need to choose what to focus on.
