FAQs
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 for programming, you need to insert batteries in the hearing instruments.
A: Ensure iCube is powered on and the battery is charged.
Ensure iCube is positioned within ~ 10 meters of the programming computer.
Run an iCube check which can be found in the Options > Preferences > Fitting Device > iCube 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.
If you have tried all of the above and are still unable to fix the problem, please contact Unitron for support.
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 fitter 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). Finally, you can navigate to the Instruments > Accessories > Smart Control or Remote Control or uDirect 2 screen and ensure that the plus/minus buttons (or the scroll wheel) have been configured to not include a volume control option.
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 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 option: Volume: Right up, Left down. Selecting this option will enable DuoLink and will allow the client to push the button on the right hearing instrument to turn both hearing instruments up, and push the button on the left hearing instrument to turn both hearing instruments down.
A: On the End Fitting > HI Setup screen, the fitter can configure the push button on wireless hearing instruments to function as either a SmartFocus control (R clarity = movement towards max clarity, L comfort = movement towards max comfort) or a volume control (Right up = volume increase; Left down = volume decrease). When the push button is configured as either of these 2 options, DuoLink will be enabled. Pushing the right hearing instrument will cause both hearing instruments to increase the assigned feature (e.g., volume up on both devices, clarity increase on both devices). Alternatively, pushing the button on the left hearing instrument in this state will cause both hearing instruments to decrease the assigned feature (e.g., volume down on both hearing instruments, comfort increase on both devices).
A: Yes, you can configure the push button to function as SmartFocus 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 option: SmartFocus - R clarity, L comfort.
A:To add the micro CIC remote to a fitting, go to End Fitting > HI Setup and select Program change, Volume up or Volume down from the dropdown box. For volume up, every time your client brings the micro CIC remote up to their ear, the volume will increase 2 dB until it reaches the maximum volume (the Volume Control Up setting under Volume Settings) and then next the HI will go back to the startup volume. If you select volume down, the HI will decrease volume by 2 dB each time until it reaches the Volume Control Down level and then it will go back to the startup volume. For example, for volume up and a Volume Control Up setting of 6 dB, the volume would change like this every time the micro CIC remote is brought up to the ear: 2 dB, 4 dB, 6 dB, 0 dB, 2 dB, 4 dB, 6 dB, 0 dB… Note that learning is not available with this feature since your client can only adjust the volume in one direction and DuoLink is not available since the micro CIC is not wireless.
A: To adjust gain, the first control to use is under Fitting > Tuning > Adaptation Manager. First adjust the Current setting of the Adaptation Manager to a comfortable level. This is the course adjustment for the gain. Then proceed to the Soft / Mod / Loud Controls or the MPO / Gain / CR / TK Controls to make further fine adjustments if necessary. It is important to adjust the Adaptation Manager first if the Automatic Adaptation Manager is enabled (which is the default setting) because the HI will gradually increase from the Current setting to the End Value setting and you want to be sure that the End Value setting will not be too high because of making fine tuning adjustments.
A: The Current setting of the Adaptation Manager is affected by your client’s age, their experience with hearing aids and their audiogram. You can override the Quick Fit default for all fittings by selecting a specific setting for the Adaptation Manager under Options > Preferences > Standard Mode or Pediatric Modes > Global parameters > Adaptation manager. The End Value is always 100% by default. Also, the Automatic option of the Adaptation Manager is always enabled by default.
A: Program number one is the Automatic Program in many products. In the End Fitting > HI Setup screen, the fitter can remove the Automatic Program from the toggle sequence in these products via the Program Toggle Exceptions task box. If the checkbox next to: ‘Include Automatic # in the program toggle sequence’ has been deselected, the patient will no longer be able to access program number one (i.e., Automatic Program).
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. Fitters 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, fitters 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.
A: Various phase canceller strengths are offered under Fitting > Configure Features > Phase Canceller to provide fitters 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, fitters 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 Ie. SmartLink, Zoomlink 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 fitter would need to add a DAI program via the Fitting > Program Manager screen. Should a neckloop-type FM system be used, the fitter 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 or uDirect 2 neck worn accessory. In these instances, the FM signal would then be provided via the uFM wireless program.

You may be prompted to change the technology level of a Flex:trial device from the Detection dialog box. If you choose to change the technology level, then follow the steps in the wizard to do so.
A: To transfer a fitting into Flex:trial devices, simply open the existing fitting session, connect the Flex:trial devices to the programming interface of your choice and click Detect. In the Detection dialog box, you may be prompted to change the technology level of the devices and you will be given the option to use the fitting from the current open session or from the newly detected hearing instrument. Select the option to use the fitting from the current open session (i.e., the client's own device settings) and then save to the Flex:trial devices.
A: To set up password protection, go to Options > Preferences > Fitting Session > Fitting, check the box beside Enable password-protected fittings, and enter the password you wish to use. Every time you save a fitting to hearing instruments with this option selected, the fitting information cannot be read back from the hearing instrument unless the correct password is in the software. Passwords are case sensitive and you have unlimited tries (in case you have deleted the password from your computer and need to input the same one again).
A: The pediatric fitting mode settings can be accessed from the Fitting Mode icon at the top right of all screens in Unitron TrueFit. Clicking on the icon will show the standard and pediatric fitting mode options. When you select one of these options, you will be given the chance to accept the change in fitting mode or cancel. Also, when you start a new session for a pediatric client, you will be provided with the opportunity to select a pediatric fitting mode right away via the generated dialog box.
A: The default settings for each of the available fitting modes can be modified in Options > Preferences > Fitting Session > Fitting Mode. The current defaults are provided in the table which can be expanded and modified as desired by clicking on the desired item and modifying it via the provided dropdown boxes.
A: There are two ways to create a mute program in Unitron TrueFit. In both cases, start on the Fitting > Program Manager screen. If the product has a Mute program listed, just add this program to your fitting in the appropriate slot. If the product does not have a mute program, first add a manual program, then proceed to the Fitting > Configure Features screen and select the manual program you just added via the program selector on the left side of the screen. Open the Input task box and select ‘Mute’ as the desired input option for the current program from the provided dropdown list. Note: if desired, the program with the ‘Mute’ input can be renamed to ‘Mute’ on the Program Manager screen.
A: If available in the product, the tinnitus masker is activated on the Fitting > Configure Features screen in the Tinnitus Masker task box. Here you can select which device has the tinnitus masker enabled for the currently selected program. After activating the feature, you can also indicate whether or not the client control on the hearing instrument or remote control will adjust the masker level while in the currently selected program. The prescribed noise level can also be manipulated in the software via the provided controls.
A: To choose the desired language for the Getting Started Guide, click on File > Print and select the Getting Started Guide language from the provided options, then proceed to print the appropriate Getting Started Guide(s) or from the End Fitting > Fitting Summary screen, select a language at the bottom of the screen, check off which Getting Started Guides you would like to print and click Print.
A: The SmartFocus slider changed from having 10 settings on both the Comfort and Clarity sides of the control to having 5 settings on the Comfort side and 15 settings on the Clarity side of the control. This change was made to provide finer granularity on the Clarity side of the control, specifically for directionality. The defaults are at positions of equivalent performance for SmartFocus. For SmartFocus 2, the Speech in Noise setting was optimized to take advantage of the SmartFocus 2 enhancements.
