 Before trying troubleshooting, please make sure to have followed the proper procedure for Personal Calibration: [<a href="/en-gb/c/learning-center/getting-started" aria-label="Learning Center/Edu PDF "Getting Started"">Learning Center/Edu PDF "Getting Started"</a>].
 Personalized calibration is a process that optimizes the audio settings of your Nuance Audio Glasses. Calibrating is optional, but it is highly recommended for optimal performance. For more information on calibration please refer to [<a href="/en-gb/c/support/faq/nuance-audio-app/hearing-configuration" aria-label="“What is personalized calibration and what is it useful for?”">“What is personalized calibration and what is it useful for?”</a>].
 In the event you’re not able to finalize this process, it may be related to two main issues:
 Issue 1: Calibration attempts in a noisy environment.
 The Calibration process is allowed if dBs is &lt;=50dB, otherwise it cannot be performed. To make sure you’re located in a quiet environment, you may try to:
 • Switch on the Glasses and open the Nuance Audio App.
 • In the Homepage, press on “Noise Tracking” -&gt; “Scan now”.
 • If the Noise level displayed (in dB), calibration is allowed if dBs is &lt;=50dB, if above the calibration cannot be performed.
 Issue 2: App freezes while Calibration Process is ongoing.
 In this event, please follow these actions:
 1. Close and open the App.
 2. Turn the Glasses off and on again.
 3. If actions 1 and 2 are not enough, proceed with the Force Restart of the Glasses [“<a href="/en-gb/c/support/troubleshooting/general-troubleshooting-steps/generic-unexpected-behavior-of-the-glasses" aria-label="How can I force restart my glasses?">How can I force restart my glasses?</a>"]

What if I'm not able to finalize the Personal Calibration process?
