Fine Tuning Screen

U:fit’s Fine Tuning screen modifies the hearing

aid frequency response, MPO and Compression

ratios. You may fine tune the hearing aid using

the Basic view (one magnifying glass) or

the Advanced view (two magnifying

glasses) for frequency response changes at all

input levels. Additionally, you can access the

Basic Control view (one screwdriver) or

Advanced Control view (two

screwdrivers) to adjust the MPO and CR

settings.

Depending on the Element model you selected,

some or all of the described controls may be

accessible within the Fine Tuning screen.

The Basic view groups all bands into three

predefined frequency regions: Low, Mid and

High.

The Advanced view gives access to all bands.

Six bands are shown at a time. A slider allows you to modify the frequency range covered by

the 6 controls.

To fine tune the hearing instrument:

1. Select the program you wish to fine tune. The active program will be highlighted

in orange. To fine tune all programs, select All Programs.

2. Select the desired view: Basic or Advanced.

3. Select the channels to be modified:

a. To individually group channels, click and drag a channel over to the next desired

channel(s). The selected channels will be highlighted. The individual grouping allows

for easier fine tuning.

b. To adjust channels one at a time, click the + or – button.

c. Note: If a fitting handle is at its maximum, only the – button appears.

d. If a fitting handle is at its minimum, only the + button appears.

4. For frequency response adjustments (gain/output), a range of fitting values can be

selected by either choosing a specific input level (i.e. Soft, Moderate or Loud) or a

specific channel or channel grouping (i.e. Low, Mid, or High). The highlighted area in

the graph shows you which frequency range is affected.

Click All to adjust all inputs and all channels.

Once All is selected, the highlighted section is adjusted by clicking + or – buttons.

To group fine tuning adjustments for MPO or compression ratio adjustments, click

MPO, CR or Gain. The affected area is highlighted in the graph. All changes can be

observed with the changed displayed values.

Only the frequencies which are currently visible in the Fine Tuning table will be modified.
