Programming in Unitron TrueFit software
This guide will lead you through the steps of fitting hearing instruments using
Unitron TrueFit fitting software. Some screens or features described in this
software instruction guide may not be available with all products. Prior to detecting
the hearing instrument(s), choose your desired programming interface:
• If using iCube, insert batteries into the hearing instruments and close the battery
door. Place hearing instruments on your client’s ears and place the iCube around
your client’s neck or place the hearing instruments inside the iCube neck loop.
• If using NOAHlink or HI-PRO with BTE or RIC hearing instruments, open the
battery door and insert the programming cable into the programming port.
Connect the other end of the cable to the NOAHlink or HI-PRO.
• If using NOAHlink or HI-PRO with ITE hearing instruments, remove the battery
door and insert the programming cable. Connect the other end of the cable to the
NOAHlink or HI-PRO.
Note: Hearing instrument controls, accessories, easy-t, easy-DAI, audio streaming,
and automatic microphone options are deactivated during programming.
Note: BTE and RIC hearing instruments are initially quick fit to a 40 dB HL flat hearing
loss configured for the left ear upon shipping. ITE hearing instruments are quick fit to
the client’s audiogram if supplied; otherwise, the devices are quick fit to a 40 dB HL
flat hearing loss.
Note: For Quantum or Quantum2 micro CIC products or Quantum2 10A custom
products, ensure you are using the white programming cable to avoid damaging the

4. Adjust the Frequency Compression to the desired setting using the More or Less
buttons. Adjusting the frequency compression impacts:
• The frequency at which the compression will begin. Below this specified cutoff, no frequency compression will be applied.
• The compression ratio or the amount of compression that will be applied in
the frequency domain above the cut-off frequency.
Note: The software will automatically calculate the starting default position of the
frequency compression based on the client's better ear audiogram and the fitting
formula. With the DSL v5 pediatric fitting formula, frequency compression default
settings are more aggressive (i.e. lower cut-off frequency, higher compression ratio)
to emphasize audibility of high frequency speech cues for children.
Note: For clients with asymmetrical hearing loss, the frequency compression settings
will be based on the audiometric thresholds from the better ear and applied to both
devices in binaural fittings.
Note: The shaded region on the slider reflects the frequency compression region
which is also displayed on the frequency response graphs.
