- 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.
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 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.
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'.
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%.
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.
