The articles below contain answers to some frequently asked questions (FAQs) about Unitron TrueFit™ software. Please refer to the Unitron TrueFit Instruction Guide for more information.
A: When you use NOAHlink or HI-PRO, batteries should be removed from the hearing instruments. The required power is provided by the programming device in these situations. If you are using a wireless hearing instrument with an iCube II for programming, you need to insert batteries in the hearing instruments.
A: Ensure iCube is powered on and the battery is charged.
Ensure that you are detecting Quantum, Quantum², Moxi, Moxi² or Max products; the original iCube is not compatible with North products.
Enable iCube in Options > iCube Configuration.
Ensure iCube is positioned within ~ 10 meters of the programming computer.
Run an iCube check which can be found in the Options > iCube Configuration menu. If the iCube check cannot locate the iCube, try deleting the iCube from Unitron TrueFit and adding it back again using the Add iCube… button.
Note: The original iCube is not compatible with North products.

A: On the End Fitting > Beeps screen in the Trial Duration task box the left and right drop boxes indicate an approximate duration.
A: The startup program is selected on the End Fitting > HI Setup screen in the Startup Settings task box. The options for Start-up program can be impacted by the settings in the Program Toggle Exceptions task box on the End Fitting > HI Setup screen. Specifically, any program that the clinician has removed from the program toggle sequence (e.g., Automatic, Easy-t, Easy-DAI) will not be included in the startup program choices.
A: The volume control range is configured on the End Fitting > HI Setup screen in the Volume Settings task box. Here you can select the Volume Control Up option (off, 6 dB, 10 dB) and the Volume Control Down option (off, 6 dB, 10 dB, 20 dB) which determine the actual volume control range.
A: The volume control can be disabled on the End Fitting > HI Setup screen using the Volume Settings box. Here you can set the Volume Control Up option to off, and the Volume Control Down option to off. Alternatively, you can ensure that the dropdown boxes associated with the hearing instrument controls in the End Fitting > HI Setup screen have been configured to not include a volume control (e.g., set the lever / dial to off via the provided dropdown box).
A: Yes, you can have independent activation and deactivation of the volume on the hearing instruments and the remote control. To deactivate the volume control on the hearing instrument, follow the instruction provided in the FAQ section regarding disabling volume controls on the hearing instrument (e.g., navigate to the End Fitting > HI Setup screen and use the Volume Settings box). Provided you have added a remote control to the fitting via the Instruments > Accessories screen and have assigned a volume control to one of the controls on the remote, the volume can still be changed via the remote control.
A: Yes, you can configure the push button to function as a volume control if that option is available on the End Fitting > HI Setup screen. On this screen you will find a configuration dropdown box for the push button that allows you to choose the options such as Volume: Right up, Left down. Some options will enable DuoLink and will allow the client to push the button on one hearing instrument to adjust both hearing instruments.
A: The program toggle and volume control functionality as well as other client controls are disabled during programming. Ensure that the hearing instruments have been re-started after programming by opening and closing the battery door. This will ensure that all the client controls, including the program toggle and volume control are enabled. Alternatively, it may be that the default loudness level and frequency of the beeps is not ideal for the client’s hearing loss or that the beeps have been disabled. To address this concern, navigate to the End Fitting > Beeps screen. In the Beep Setup task box adjust the beep intensity and frequency level via the provided dropdown boxes to improve audibility of the indicators. In the Beep Enabling task box, it is possible to activate/deactivate the desired indicator beeps.
A: The amount of high frequency gain in the hearing instruments can be determined by a number of factors. Clinicians desiring more high frequency gain should ensure that the devices have been Quick Fit to the desired target level using the Quick Fit icon on the tool bar. The acoustics of the fitted hearing instrument(s) should also be configured in the software via the Instruments > Acoustics screen so that the Quick Fit logic is appropriate. Also, should more gain be required, clinicians could navigate to the Fitting > Tuning screen and increase the Adaptation Manager setting in the Adaptation Manager box.
In addition, the reduction of available gain that can occur following the feedback optimization test, i.e. it can hinder the amount of available high frequency gain for a particular fitting. Clinicians should view the feedback optimization screen to determine whether the currently used coupling and acoustic characteristics of the fitting have resulted in a restricted maximum stable gain curve after the feedback test. If necessary, changing to a more occluded fitting could provide the ability to offer more high frequency gain.
A: The feedback optimization test determines the maximum stable gain that can be provided in an individual fitting to ensure a feedback-free fitting. If the feedback test did limit the available gain beyond what is desired for the fitting, improvements to the feedback path can be made and the test can be re-run afterwards. Such improvements could involve reducing the amount of venting, improving the fit/retention of the ear mold, providing a more occluding dome for slim tube and RIC fittings. Whenever the acoustic coupling in a fitting is changed, the fitter should first navigate to the Instruments > Acoustics screen to properly include the acoustic change in the software logic, and then re-run the feedback optimization test in the Fitting > Feedback Optimization screen. If available, you may also select the checkbox to increase the gain by up to 5 dB.
A: Various phase canceller strengths are offered under Fitting > Configure Features > Phase Canceller to provide clinicians with the ability to address various degrees of feedback and any possible sound quality concerns. The default setting is 'Maximum' for the Automatic Program and all acoustic manual programs once the feedback optimization test has been performed as this strength has been found to provide the optimal feedback management performance. In those instances where a client reports concerns with the sound quality of tonal signals (e.g., music) or particular environmental sounds, clinicians could adjust the strength of the phase canceller downwards one step at a time to optimize the balance between lack of feedback and lack of sound quality complaints.
A: Unitron hearing aids are compatible with all leading FM systems i.e. SmartLink, Zoomlink, Roger to name a few. For those FM fittings using standard BTE devices, and universal audioshoes, the FM receiver can be plugged into the audioshoe using the standard 3 pin europlug. The clinician would need to add a DAI program via the Fitting > Program Manager screen. Should a neckloop-type FM system be used, the clinician would need to ensure they add a telecoil-based input program via the Fitting > Program Manager screen. The input type could be confirmed by navigating to the Fitting > Configure Features screen, and choosing the Input task box for the desired program. In addition, with all wireless enabled devices, 3-pin Europlug FM receiver units can be plugged directly into the bottom of the optional uDirect 3 neck worn accessory. In these instances, the FM signal would then be provided via the uFM wireless program.
