The function of this icon is to perform automatic self-tests to assist in technical troubleshooting. A green tick (checkmark) indicates that everything is running correctly. A red cross (X) indicates that something is wrong. Click the icon to see the issue. Most commonly, the Tobii eye tracker cable has not been plugged into the laptop/PC. If you have network issues, the diagnostic tool will advise of this. To run a diagnostic, click on the red icon and a window will open. Press ’Start’ in the bottom left corner of the window. When it has finished checking all the properties that might be causing an issue, click ’Copy to clipboard’ and paste the information into an email to send to your IT personnel for further assistance. If the problem persists please contact Lexplore Support.       - [Getting Started](https://info.lexplore.com/en/support/getting-started?hsLang=en#main-content) - [Logging in](https://info.lexplore.com/en/support/getting-started?hsLang=en#logging-in) - [Technical Requirements with an eye tracker](https://info.lexplore.com/en/support/getting-started?hsLang=en#technical-requirements-with-an-eye-tracker) - [Installation with eye tracker](https://info.lexplore.com/en/support/getting-started?hsLang=en#installation-with-eye-tracker) - [Administration](https://info.lexplore.com/en/support/getting-started?hsLang=en#administration) - [Integrations](https://info.lexplore.com/en/support/getting-started?hsLang=en#integrations) - [Web Assessment](https://info.lexplore.com/en/support/web-assessment?hsLang=en#main-content) - [Get started with Web Assessment](https://info.lexplore.com/en/support/web-assessment?hsLang=en#get-started-with-web-assessment) - [Learn more about Web Assessment](https://info.lexplore.com/en/support/web-assessment?hsLang=en#learn-more-about-web-assessment) - [FAQ](https://info.lexplore.com/en/support/web-assessment?hsLang=en#faq) - [All about Assessments](https://info.lexplore.com/en/support/all-about-assessments?hsLang=en#main-content) - [General](https://info.lexplore.com/en/support/all-about-assessments?hsLang=en#general) - [Preparations before Assessment](https://info.lexplore.com/en/support/all-about-assessments?hsLang=en#preparations-before-assessment) - [Equipment for performing assessment](https://info.lexplore.com/en/support/all-about-assessments?hsLang=en#equipment-for-performing-assessment) - [During an assessment](https://info.lexplore.com/en/support/all-about-assessments?hsLang=en#during-an-assessment) - [After assessment](https://info.lexplore.com/en/support/all-about-assessments?hsLang=en#after-assessment) - [Administration](https://info.lexplore.com/en/support/administration?hsLang=en#main-content) - [Student Management](https://info.lexplore.com/en/support/administration?hsLang=en#student-management) - [Staff Management](https://info.lexplore.com/en/support/administration?hsLang=en#staff-management) - [Portal functionality](https://info.lexplore.com/en/support/administration?hsLang=en#portal-functionality) - [Organisation Settings](https://info.lexplore.com/en/support/administration?hsLang=en#organisation-settings) - [Academy](https://info.lexplore.com/en/support/academy?hsLang=en#main-content) - [Start with this](https://info.lexplore.com/en/support/academy?hsLang=en#start-with-this) - [Ambassador courses](https://info.lexplore.com/en/support/academy?hsLang=en#ambassador-courses) - [Assessments courses](https://info.lexplore.com/en/support/academy?hsLang=en#assessments-courses) - [Insights & Analysis](https://info.lexplore.com/en/support/academy?hsLang=en#insights-analysis) - [The Reading Journey - Theory](https://info.lexplore.com/en/support/academy?hsLang=en#the-reading-journey-theory) - [The Reading Journey - Practical](https://info.lexplore.com/en/support/academy?hsLang=en#the-reading-journey-practical) - [The Reading Journey/Library - Workshops](https://info.lexplore.com/en/support/academy?hsLang=en#the-reading-journey-library-workshops) - [Understand and manage the Results](https://info.lexplore.com/en/support/understand-and-manage-the-results?hsLang=en#main-content) - [Understand the results](https://info.lexplore.com/en/support/understand-and-manage-the-results?hsLang=en#understand-the-results) - [Navigate the results](https://info.lexplore.com/en/support/understand-and-manage-the-results?hsLang=en#navigate-the-results) - [Results where review is needed](https://info.lexplore.com/en/support/understand-and-manage-the-results?hsLang=en#results-where-review-is-needed) - [Manage results](https://info.lexplore.com/en/support/understand-and-manage-the-results?hsLang=en#manage-results) - [Other](https://info.lexplore.com/en/support/understand-and-manage-the-results?hsLang=en#other) - [Reading development](https://info.lexplore.com/en/support/reading-development?hsLang=en#main-content) - [Theory about reading development](https://info.lexplore.com/en/support/reading-development?hsLang=en#theory-about-reading-development) - [Fluency Practice](https://info.lexplore.com/en/support/reading-development?hsLang=en#fluency-practice) - [About Lexplore Reading App for students](https://info.lexplore.com/en/support/reading-development?hsLang=en#about-lexplore-reading-app-for-students) - [Information to guardians](https://info.lexplore.com/en/support/reading-development?hsLang=en#information-to-guardians) - [Support](https://info.lexplore.com/en/support/support?hsLang=en) [![Chill listening crop-3](https://info.lexplore.com/hs-fs/hubfs/Lexplore_22_Logo.png?width=76&height=24&name=Lexplore_22_Logo.png "Chill listening crop-3")](https://lexplore.com?hsLang=en) A clear view of reading Copyright © 2026, Lexplore Nordic AB
