Click the Detect button.

Identify hearing instruments by either pressing the push button of the hearing instrument (if applicable) to see a highlight in dialog or click the Play Beep button to play a beep in the corresponding hearing instrument.

Assign side information to the hearing instruments.

Click Continue and follow the workflow.

Yes, equalizer adjustments can be viewed in the App Equalizer tool box on the Fitting->Tuning screen. Adjustments to the automatic program apply to all environments and are not adjusted individually for each environment.

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.

To change the technology level of a FLEX:TRIAL device, go to the Instruments > Technology Change screen, click on the new technology level that you would like to use and follow the instructions in the wizard. 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.

Navigate to the End Fitting>HI Setup screen, and in the TV Connector task box select “Manual” (not available in pre-Discover hearing instruments).

Upon detecting devices, TrueFit will read the latest values for the equalizer. The Tool Box preview will indicate if your client has made any changes in the current program you are reviewing. If changes have been made you can see them in the App Equalizer tool box on the Fitting->Tuning screen. If your client has not make any changes to the selected program, the values will be set to zero. Note: App equalizer changes made to streamed signals, including Media, Bluetooth Phone and Roger Direct cannot be displayed in TrueFit.

Click on the label under each slider to highlight the region in the curve displays: Bass, Mid and Treble.

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.

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).

  • Ensure iCube II is powered on and the battery is charged
  • Enable iCube II in Options > iCube II Configuration
  • Use the iCube II dedicated dongle
  • Ensure iCube II is positioned within ~ 10 meters of the programming computer
  • Run an iCube II check which can be found in the Options > iCube II Configuration menu. If the iCube II check cannot locate the iCube II, try deleting the iCube II from Unitron TrueFit and adding it back again using the Add iCube II button.

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.

These markers indicate the original position when the hearing instruments were detected. This provides a visual reminder of your client’s initial settings when you move the sliders or press reset.

Pressing the Reset button will return all of the sliders to the default (zero) position for the currently selected program, the curves will reflect the changes made and the App Equalizer settings for that program will be reset on the HIs.

To see if your client's phone is compatible with the Remote Plus app, use our Compatibility Checker

If available in the product, the tinnitus masker is activated on the Fitting > Tuning 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.

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.

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 'Moderate' 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.

Using hearing instruments

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.

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 programming device, you need to insert batteries in the hearing instruments or ensure the hearing aids are charged for 3 hours prior to programming.

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 will not be included in the startup program choices.

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.

On the End Fitting > Beeps screen in the Trial Duration task box the left and right drop boxes indicate an approximate duration.

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.

All Unitron devices from Discover Next onwards are compatible with Roger Direct.

Most other 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.

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).

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.

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 calculated to the desired target level using the Recalculate 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 calculation 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  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.

Remote Adjust

Yes, previous adjustments, including the initial fitting can be selected in the Remote Plus app by navigating to Settings > My hearing aids > Hearing aid adjustments. Simply select the preferred adjustment and tap 'Apply Adjustment'.

The app equalizer and Remote Adjust use the same fundamental implementation. When you increase or decrease either the equalizer or Remote Adjust, there is a gain offset that is applied to the base fitting. The effect of an adjustment is dependent on the direction of the change (up or down) and the input level (soft or loud). 

The basic premise is: 

When you increase the gain offset level, the gain for soft inputs are increased more than the gain for loud inputs.

When you decrease the gain offset level, the gain for loud inputs are decreased more than the gain for soft inputs.

The offset applied by the Equalizer and Remote Adjust are additive which means that it is possible to “max out” the effectiveness of them if your client’s fitting is close to the max output. If this happens, the experience is when the client goes to increase change an equalizer value they might not experience any change in the sound performance.

If this happens, we recommend that your bring the client back into the clinic and update their fitting. 

Also remember when your client applies a remote adjustment, the app equalizer will be reset to zero. This will allow your client to hear the exact changes you made and if needed, they can further refine their hearing experience with the equalizer later. 

When a new adjustment is made available, your client will receive a notification on their smartphone. Instruct them to click on the notification to access the adjustment directly. They will also be alerted in the Remote Plus app if there is a new Remote Adjust message. Instruct them to click on 'See Adjustment' to access the message. Existing adjustments can also be accessed by navigating to Devices > Remote Adjust.

If the AAM isn’t 100% in the session that you opened, you will receive a warning when you go to modify the gain offset for your client. This is the same warning that you receive during a standard TrueFit session when AAM is less than 100%. 

For Blu products and newer, the frequency response as well as up to six additional features (microphone mode/dynamic noise reduction, speech enhancement, noise reduction, AntiShock 2, phase canceller, and wind control) can be modified for each program on the hearing aids. The parameters available for adjustment depend on the program selected.

For Discover Next products the frequency response of each program on the hearing aids can me modified.

You have the ability to go up or down by 15 steps with each offset. Each step that you go is approximately equal to 1db. This means that the max gain change that can be applied in a remote adjustment is +/- 15 db. We recommend that if you need to make changes greater than 8db, you should bring your client in for an appointment and a full fitting review. 

After you have a follow up fitting in-clinic and save changes to the hearing instruments, all of the previous remote adjust sessions will no longer be accessible to your client. Remote Adjust sessions are always based on a known set of parameters that were part of the original adjustments in TrueFit. Once you make a change to the original fitting in TrueFit and save that session to the hearing instruments, all of those gain offset values are no longer valid since they were based on the old frequency response settings.
